Title: [ANN] cpuminer-opt v24.1, Optimized multi-algo CPU miner for x86_64 and AArch64 Post by: JayDDee on February 18, 2020, 05:20:55 PM This is the home of cpuminer-opt, the optimized CPU miner.
Now supporting AArch64 Supporting over 90 agorithms with many optimized for CPUs with the latest technologies: Intel Haswell: AVX2 AMD Zen1: AVX2 and SHA AMD Zen3, Intel Alderlake*: AVX2, SHA and VAES Intel Skylake X: AVX512 AMD Zen4, Intel Rocketlake: AVX512, SHA, and VAES Orange Pi-5: NEON, AES, SHA2 Raspberry Pi-4B, Apple M2*: NEON Older 64 bit CPUs with SSE2 are also supported, see below for requirements. *Alderlake and subsequent Intel desktop architectures are hybrid architecture with AVX512 disabled. *Apple M2 is supported using a Linux VM. Downloads Linux can be compiled from source for x86_64 and AArch64. Windows binaries are available for x86_64. Windows binaries do not support CPU groups and are limited to 64 threads. Support for CPU groups requires compiling from source with CPU groups enabled, see Wiki for details. Download only from the official JayDDee git repository. There may be malware masquerading as cpuminer-opt, stay alert. I no longer post links in new mesages and I don't post direct links to files. Any such links should be treated with suspicion. The only valid download link is below and directs to a landing page that can be examined for legitimacy before any files are downloaded. Latest release including Windows binaries https://github.com/JayDDee/cpuminer-opt/releases Documentation https://github.com/JayDDee/cpuminer-opt/wiki List of supported algoritms https://github.com/JayDDee/cpuminer-opt/wiki/Supported--Algorithms Source code https://github.com/JayDDee/cpuminer-opt New in v24.1 #414: fix bug in merkle error handling. #416: change $nproc to $(nproc) in build scripts. #420: change some inline function definitions to static inline. #413: Fix formatting error for share result log when using no-color. Faster 2 way interleaving. Cleanup sha256 architecture targetting. Full change log: https://github.com/JayDDee/cpuminer-opt/blob/master/RELEASE_NOTES Requirements: CPU: - x86_64 architecture CPU with a minimum of SSE2 support. This includes Intel Core2 and newer and AMD equivalents. - Arm CPU supporting AArch64 and NEON. 32 bit CPUs are not supported. Older CPUs are supported by open source cpuminer-multi by TPruvot but at reduced performance. Mining on mobile devices that may otherwise meet the requirements is not recommended due to the risk of overheating and damaging the battery. Mining has unlimited demand, it will push any device to or beyond its limits. There is also a fire risk with overheated lithium batteries. Beware of apps claiming "mobile only mining". There is no such thing, they aren't miners. If a mobile CPU can mine it any CPU can. OS: 64 bit Linux OS. Debian and Fedora based distributions including Ubuntu, Mint, RHEL and clones are known to work and have all dependencies in their repositories. Others may work but may require more effort. Windows 7 or newer 64 bits is supported using the pre-compiled binaries x86_64 package or may be compiled from source using MinGW & MSys2. There is no support for Windows on ARM at this time FreeBSD is not actively tested but should work, YMMV. Apple MacOS is supported using a Linux VM, native support is not yet available. Alt OSs like Haiku & ReactOS are not supported. Security warning Cryptocurrency miners are often flagged as malware by antivirus programs. This is usually a false positive, they are flagged simply because of what they are. However, some malware has been spread using the cover that miners are known to be subject to false positives. Always be on alert. The source code of cpuminer-opt is open for anyone to inspect. If you don't trust the software don't download it. Some cryptographic code has been taken from trusted sources but has been modified for speed at the expense of accepted security practices. This code should not be imported into applications where secure cryptography is required. Errata: Old algorithms that are rarely used or are too difficult to mine with a CPU will not get the latest optimizations. Cryptonight and variants, Hodl & Argon2a are no longer supported, use older version or other miners. Donations cpuminer-opt has no fees of any kind but donations are accepted.

Title: Re: [ANN] cpuminer-opt v3.12.3.1, open source optimized multi-algo CPU miner Post by: JayDDee on February 20, 2020, 07:23:18 AM I've created a wiki page for cpuminer-opt. It's all one page with no index, sorry but I don't know how to make it more structured
other that breaking it up into seperate files. Users may want to scroll past the first half, it's just copied from README files. The interesting part is the log report descriptions that start about half way down. A lot of changes have been made to the miner's displayed output and a lot of new info is provided. I attempted to make it as intuitive as possible while prioritizing and highlighting the most important points. I also tried to limit redundancy by not displaying the same data in different forms or statistics that can be easilly derived from other displayed data. The data can be used with data obtained from other sources to provide even more advanced info. For example, block reward and coin exchange rates are not known to the miner but when combined with pool and exchange data can build a full profitability profile. The new log reports were the result of 2 minds: the geeky user who wanted all the data available, and the developper who wanted to provide the data in the most efficient manner, as raw as possible while still being understandable to a moderately experienced user. It's all here... https://github.com/JayDDee/cpuminer-opt/wiki It's still rough around the edges, lots of typos and missing topics, buit it's a start. Title: Re: [ANN] cpuminer-opt v3.12.4.1, open source optimized multi-algo CPU miner Post by: chrysophylax on February 23, 2020, 01:45:12 PM Still at it mate ...
You are still sitting in my 'highest respect' list. Always looking forward to what you may be doing next. Massive updates to the codebase I see also. This profile will be a legend in no time ;) #crysx Title: Re: [ANN] cpuminer-opt v3.12.4.1, open source optimized multi-algo CPU miner Post by: JayDDee on February 23, 2020, 08:14:58 PM Nice to hear from you Chrys.
Mining isn't what it used to be but writing SW keeps me out of trouble. I've kinda lost touch with you and chainworks, how's that going? It seems like you're always exploring new ventures. Title: Re: [ANN] cpuminer-opt v3.12.4.2, open source optimized multi-algo CPU miner Post by: JayDDee on February 23, 2020, 08:39:41 PM cpuminer-opt-3.12.4.3
https://github.com/JayDDee/cpuminer-opt/releases Solo mining with getwork is now working again with improved log reporting. Edit: fixed segfault in getwork from v3.12.4.2. See RELEASE_NOTES for detailed changelog. Title: Re: [ANN] cpuminer-opt v3.12.5, open source optimized multi-algo CPU miner Post by: JayDDee on March 01, 2020, 07:06:01 PM cpumminer-opt-3.12.5
This release should bring an end to the flurry of releases recently to address problems with share statistics for both getwork and stratum mining. Stats should now be correct and robust with the ability to verify many mining performance parameters. A list of variants of yespower algorithms and parameters has been added to README.md. These algos can be mined by cpuminer-opt simply by specifying their parameters. See OP for more info.

Mining isn't what it used to be but writing SW keeps me out of trouble. I've kinda lost touch with you and chainworks, how's that going? It seems like you're always exploring new ventures. Always nice to see all that is happening with you mate ... Especially the positive, even though negative is always part of the equation. CWI is doing a LOT. Mostly backend stuff and not stuff I really want to bring out here in public. You know what happens if even a small amount is leaked out, then taken considerably out of context. Two years have passed since the reset and continuation of theFARM, and that is going strong, renting some of the units through MiningRigRentals under the CWI-Rental banner, with a new Mine (Rebuild of Amethyst Mine) underway for all areas of mining. New codebase being built for the template of the coins we have to rebuild, and ultimately being integrated into one MasterCoin we have codenamed CoinX for the time being. CPU mining is one of our goals for Amethyst Mine and I assure you, even though mining is not what it used to be, it is still as exciting as it was when it first started. Never in any case has the memory of your help in the background when I was stumbling at the time of compilation and understanding, has left my mind. Your help THEN has always been a reminder that decent people exist in Crypto. Always that respect mate, no matter whether we see eye to eye or not (and I fail to remember when it was not - but there you have it). What you have done with CPUMiner-Multi is amazing. CPUMiner-OPT is in a league of it's own now. The leaps and bounds is well worth the time and effort to reacquaint yourself with the coding world, and a huge success it seems to be. I do see at times you get frustrated, but that comes with the territory mate. We all do, especially with the trolls. There is much to do and still a long road to tread, but as long as we tread and cut the road ourselves, we follow in no others footsteps, and that my friend, are steps worth taking. As for CWI, a lot more has happened in the background and the plans are seemingly coming to fruition this year. All the puzzles' pieces shall fit some time soon in the big picture. One thing is for sure though, if there is anything that we can do together, my door is always open to you. New Ventures for us are also backend mostly, and can discuss with you privately, but none of them are small. We have become a very precise instrument, nay a tool, to deal with all we have undertaken, and hone it all into an enterprise that is worth the long (almost 9Year) effort I have personally invested in Crypto thus far. We have 'good' people with us, and they are doing great things. That door is also open to you. Keep doing good things JDD (JoBlo or whatever Pseudo you wish to use) - as you usually do mate. #crysx Title: Re: [ANN] cpuminer-opt v3.12.5, open source optimized multi-algo CPU miner Post by: orlandoblim on March 04, 2020, 06:21:41 AM Can we discuss about the price?
Title: Re: [ANN] cpuminer-opt v3.12.6, open source optimized multi-algo CPU miner Post by: Saisher on March 07, 2020, 09:47:22 AM I was redirected from my thread asking about my hardware for mining, is it still profitable mining with CPU I see a lot of algo that is compatible to this mining software but can it compete and what's the best coin to mine using this software, do you have a video tutorial for your software.
Title: Re: [ANN] cpuminer-opt v3.12.6, open source optimized multi-algo CPU miner Post by: JayDDee on March 07, 2020, 05:00:33 PM Benchmark is broken in cpuminer-opt-3.12.6. It will be fixed in the next release.
Mining is not affected. Use v3.12.5 for benchmarking until the fix is released. Edit: v3.12.6.1 is released with benchmark fixed. Title: Re: [ANN] cpuminer-opt v3.12.6, open source optimized multi-algo CPU miner Post by: chrysophylax on March 08, 2020, 01:19:34 AM I was redirected from my thread asking about my hardware for mining, is it still profitable mining with CPU I see a lot of algo that is compatible to this mining software but can it compete and what's the best coin to mine using this software, do you have a video tutorial for your software. I think ... I think that these questions really should be directed to a trading (read - gambling) thread about price and the trade systems. I think that that you should know the differences between coins and what they do, or don't do in most cases, and what the benefit is of those coins distanced from 'money'. I think that who ever creates applications, improves them and optimizes them (like this project), and continues to do so, is adding more value to Crypto itself, than to the 'price' that most of you out there are so obsessed with. Who cares about price? Most of you that are out there fumbling their way trying to do the complete opposite of what Crypto was actually designed for, by trying to make more of the money that enslaved us all in the first place. Who cares about the Technologies? The people that care about the optimization and improvement of such technologies and the development of such things for the betterment of Crypto. Like this project. Who cares about value in Crypto? We should ALL care, but very little do. Price and FIAT (Governement OWNED cash) is all that most care about, meaning not many have a good grasp of what Crypto really is about. So when you ask about 'price', 'profitability', and whether sofwtare 'competes' in this arena, you are asking the wrong questions in the wrong place. This thread is about the optimization, development, and GROWTH of the code and application, than the 'price' something is, which is a moot subject here. It saddens me to see Crypto over the 9Years I have been around in this 'scene', to watch the idea of 'freedom' get turned into 'slavery' because all you want is to turn Crypto into Cash. Crypto = Freedom/People. Cash = Government/Slavery. CPUMiner-OPT = development. Who gives a damn about the money other than those that lust for it? I sure as hell don't, and I can gurantee ANYONE that knows what Crypto is about and respects the core values of Crypto, is the same. So please don't smear this thread and the 'clean' talk of development and functionality with the filth that 'price' and 'cash' and 'profit' always end up doing. JDD = keep hammering away at the code mate. You are doing an AWESOME job! #crysx Title: Re: [ANN] cpuminer-opt v3.12.6, open source optimized multi-algo CPU miner Post by: JayDDee on March 08, 2020, 02:22:53 AM I was redirected from my thread asking about my hardware for mining, is it still profitable mining with CPU I see a lot of algo that is compatible to this mining software but can it compete and what's the best coin to mine using this software, do you have a video tutorial for your software.

I've made it clear in the past I don't give advice on mining, only technical information. And I don't compete.

Title: Re: [ANN] cpuminer-opt v3.12.6.1, open source optimized multi-algo CPU miner Post by: JayDDee on March 11, 2020, 01:11:36 PM This was an interesting test but I don't see the point. It's conclusion was Clang/AOCC didn't improve performance
when compared against GCC. The testing was also incomplete. There was no live test to confirm shares are valid and no control test of Clang without AOCC. Clang, with or without AOCC, is not recommended and not supported for cpuminer-opt.

I was just wondering: in the current periodic share/speed report, is there the raw hash rate, the one the machine can actually compute? Not sure if the value in parenthesis is this number as it seems quite smaller than the value I got from older versions. Does --benchmark still output this value reliably? Thanks.

Not sure if the value in parenthesis is this number as it seems quite smaller than the value I got from older versions. Does --benchmark still output this value reliably? Thanks. Yes, the number in parentheses is calculated by counting hashes. This calculation is also used in the new block report to calculate TTF, thread hash meter, and benchmark total. This is called the "reference hash rate". Anything related to actual shares is called the "effective hash rate". You can find details in the Wiki... https://github.com/JayDDee/cpuminer-opt/wiki/Console-Logs As far as interpreting the values, the reference hashrate is simply the sum of the last sample from each thread. It can be volatile if there is other activity on the CPU. Some miners average it but I prefer discrete samples. Newer miner versions should not have a slower ref hash rate. If anything they should be faster if not equal. If you find otherwise please post the details so I can investigate.

Title: Re: [ANN] cpuminer-opt v3.12.8.2, open source optimized multi-algo CPU miner Post by: malafaya on April 29, 2020, 02:23:02 PM This may be nonsense but please bear with me:
Blake2b seems to be optimized for AVX2. Power2b just supports SSE2. Assuming that power2b uses blake2b internally, and the latter is/may be optimized with AVX2, my question is couldn't power2b use blake2b's already existing AVX2 optimizations, and not fall back as a whole to SSE2? Title: Re: [ANN] cpuminer-opt v3.12.8.2, open source optimized multi-algo CPU miner Post by: JayDDee on April 29, 2020, 03:25:19 PM It isn't nonsense at all, actually a very good question.
Vectorization can be implemented 2 ways, linear and parallel. Linear can be used when a single data stream has repeated instructions on contiguous data. Parallel is multiple data streams, similar to a GPU but with some strict limitations. First the data streams must be interleaved. There must not be any data dependencies that would cause code divergence between lanes. All lanes must execute the exact same code in the same order. Also the interleaved data must be contiguous to get any performance benefit. When possible, parallel is easier to implement because it's basically SIMD versions of the same scalar instructions. Some code segments can do linear only, some parallel only, some both and some neither. Blake2b can do parallel but only represents a small portion of the entire algo. The rest of Yespower has data dependencies that prevent parallel vectorization but has some segments that can benefit from linear vectorization. One other barrier is memory throughput. If an algo is already I/O bound (mempory hard) linear vectors still have to access the same amount of memory but with fewer instructions. That won't help (example lyra2z330). Parallel vectorization increases memory usage by 4x or 8x depending on the number of lanes making the bottleneck worse. It's an unfortunate reality that CPU vectorization is a losing battle in crypto mining. Any vectorization a CPU can do, a GPU can do better. Algos that favour CPUs typically have limited vectorization potential. Many new algos are specifically designed to exploit the advantages of CPUs over GPUs and ASICs.

I keep getting rpc errors from miner. I know rplant said solo is broken in his version, but he’s not going to fix it because he wants people using his pool. I assume not if rplant doesn't work, but you could give it a try and post your results. If it doesn't work I can take a look at the debug output to see if there's something obvious.

There is also no reason it would exit silently unless it crashed. I'm not familiar with Windows crash debugging so I don't know how to determine if it crashed or how it crashed. I can only suggest trying different things to see if there's a pattern. - try default thread count - try stratum+tcps port, if available - try different algo same pool - try different pool same algo I'll try to find more info about the RPC error solo mining.

- It's a crash - Windows only - Minotaur algo only - AVX build and above only (sse2 & aes-sse42 work) - More than one thread only Windows only crashes have typically been due to data misalingment in the past. AVX introduces 256 bit vectors which require stricter alignment, Windows defaults to 128 bit alignment. Minotaur uses the _ALIGN macro to specify alignment, which is defined in compat.h but isn't included in minotaur.c. The missing macro defnition apparently doesn't break the compile but leaves the data at the default alignment. I have no idea why the number of threads makes a difference. It should be fixed by including compat.h in minotaur.c. That's the analysis, now I have to test it. Testing on Windows will take some time, it's a lot more work, my Windows test machine is on a differnt floor.

I don't know how to implement segwit in the miner. This will likely affect other coins that enforce segwit. hmm. There is a miner available to do solo mining of Ring (Minotaur algo). But, it generates very low hash rate compare to other miners. https://github.com/litecoincash-project/cpuminer-multi Your miner is better than many other miners, e.g. rplant miner, it is only lacking solo mining of Minotaur. If you able to add this, I think then it will be best CPU miner. Title: Re: [ANN] cpuminer-opt v3.13.1.1, open source optimized multi-algo CPU miner Post by: SpceGhst on May 18, 2020, 11:25:36 AM Don’t know if this helps or not, but Ring is built on BTC core 18 which changed getblocktemplate. This is from core website.
Notable changes Mining Calls to getblocktemplate will fail if the segwit rule is not specified. Calling getblocktemplate without segwit specified is almost certainly a misconfiguration since doing so results in lower rewards for the miner. Failed calls will produce an error message describing how to enable the segwit rule. I found this for Litecoin: You need to explictly declare the segwit rule: litecoin-cli getblocktemplate '{"rules":["segwit"]}' Title: Re: [ANN] cpuminer-opt v3.13.1.1, open source optimized multi-algo CPU miner Post by: JayDDee on May 18, 2020, 03:33:58 PM Adding segwit support would be a significant improvement and I'm willing to give it a shot.
However, I will need a lot of help with testing and progress will be slow with a lot of back and forth. The changes will affect all solo mining with any algo. The good news is that if segwit works for ring it should work for any coin/algo. The bad news is that it could break solo mining for others. If you can use Linux (Ubuntu preferably) it would save a lot of time by compiling it yourself. You wouldn't need a seperate PC, a Virtualbox VM would work. With that you could make small code changes and test them quicker instead of waiting for me to build Windows binaries. You would also be able to do a control test with the litecoin-cash fork as there are no binaries available for it. The code changes would be made by me and you would test them and report your results. The basic plan is as follows: 1. Me: analyze the code changes and merge the segwit code. You: Perform a control test solo mining with the litecoin-cash fork (if using Linux) 2. Me: provide source (if using linux) or Windows binaries with new code. You: test and report 3. Me: fix bugs and return to step 2 until it's working correctly. 4. You: once minotaur is working with GBT/segwit do some regression testing by solo mining other coins to make sure nothing broke. Let me know if this plan works for you. Other volunteers would also be welcome to help with testing, particularly regression testing if they are already solo mining their favorite coin.

I can try Ring (because it's what I've already installed on my computers) and the one I'm most familiar with (also the one that knocks on the door); but I guess the other currencies (CPU only, which is what I can help with) shouldn't be much different; - put the wallet down - sync (which is the heaviest, but a pruning = 100 MB) - request a legacy address - put a mine against your node I don't understand very well about 'getwork'; if i use it myself or if the blockchain responds to that command? if it is the latter, I don't see that command between rpc commands; maybe my other colleagues know more about it Let's say I'm new, among the RPC commands, mining ... but I dock quickly, if you tell me what to do exactly or where to read I can keep up with you.

Well I don't know if I'm the best to give instructins, I've never actually solo mined. Getwork is the old protocol still used by many coins. Getblocktemplate (GBT) is the new protocol used by Bitcoin and many clones. I'm adding segwit support to GBT. The command line syntax is slightly different between them but there is some auto-detection in the code. Generally GBT will be tried first then fallback to getwork. The messages at startup should be clear on which is being used. It would be good if you could do a control test mining ring with the litecoincash fork of cpuminer-multi (step 1 of the plan): https://github.com/litecoincash-project/cpuminer-multi The main goals are 1: to confirm it can connect, get work from the server, and start hashing; 2: confirm it can find a block which could take some time. It would be good to know if the code I'm copying actually works. I recommend adding -D -P the command line to gather more data in case of problems. You can also add --hash-meter to confim it's hashing if things are too quiet. I've started analyzing the code and so far it looks like the segwit code is mostly protected when segwit is not enabled so adding segwit should break anything (fingers crossed).

I also did solo mining with this in mainnet without any issue, but didn't able to find any block. Cause my PC is old and this miner generates low hash rate compare to others.

Adds support for Segregated Witness (segwit) to GetBlockTemplate. https://github.com/JayDDee/cpuminer-opt/releases/tag/v3.13.2-segwit-test This is a test release not intended for production use. Users mining solo are invited to test this release and report their results. Other users may want to wait for the next general release before upgrading. Test notes: Minotaur algo (Ring coin) should be tested against the litecoincash fork of cpuminer-multi. Other algos should be tested against cpuminer-opt-3.13.1.1 for any regressions (things that worked in v3.13.1.1 but not in v3.13.2). Testing the new segwit support for coins other than Ring should probably wait until it's known to work with Ring.

Test notes: Minotaur algo (Ring coin) should be tested against the litecoincash fork of cpuminer-multi. Other algos should be tested against cpuminer-opt-3.13.1.1 for any regressions (things that worked in v3.13.1.1 but not in v3.13.2). Testing the new segwit support for coins other than Ring should probably wait until it's known to work with Ring. Congratulations dude, it's working. ;D I tested Minotaur algo with flag `-t 1` `-t 2` `-t 3` and without flag `--threads=n`. It worked without any issue. Here is the debug log file. https://drive.google.com/open?id=1NWx7BHPhz9IlvIyV0j8eidXq6Yj81VvR https://i30.servimg.com/u/f30/17/76/10/38/th/jaydde12.png (https://servimg.com/view/17761038/924) I will check other algo one by one and will post the results here.

I guess if you prepare for the worst it doesn't happen. ;) This is the first time anyone has confirmed to me that GBT works in cpuminer-opt. I just kept my hands off it and waited for users to complain. I see there's still some work to be done, GBT still uses the old "new block" log. I also didn't see a 5 minute summary log, did you run long enough? Without the new "new block" log that's the only way you'll see a hash rate. It would be nice to know how the performance compares. The hash rate tends to vary so it might be difficult to compare. Please include your CPU model. I've been thinking about Discord but will wait, development has slowed considerably. The code has been optimized for the latest x86_64 CPUs and many new algos are incompatible with cpuminer. I don't see a lot of activity in the immediate future. If that changes I may reconsider.

But, it shows 5 mins summary when I do pool mining. I get around 50 kh/s with 1 thread using LitecoinCash cpuminer-multi, but your miner is generating 80-85 kh/s. It is about 60% more hash rate than LitecoinCash cpuminer-multi. You can easily compare the hash rate with these screenshots. cpuminer-opt-3.13.2-segwit-test https://i30.servimg.com/u/f30/17/76/10/38/jaydde13.png LitecoinCash cpuminer-multi https://i30.servimg.com/u/f30/17/76/10/38/lcc-mi10.png And this is the summary of 3 hours and 20 mins using cpuminer-opt v3.13.1.1.

I think you may find you get both formats if you let it run long enough. I have an idea why but will wait for your data. Edit: I did some analysis and I found there may be a conflict with longpoll. With stratum, getwork, or GBT without longpoll the miner threads request new work by signalling the workio thread. When longpoll is enabled the longpoll thread requests new work, however, the miner threads via workio also continue to request new work. This is why the new block reporting is inconsistent. When workio requests new work the new format is used, longpoll still uses the old format. You previously reported an HTTP error that went away when you disabled longpoll. The error may have been due to the conflict of both workio & longpoll requesting work. As a result I want to change the focus of testing. Contrary to my last recommendation you should continue to use -P as well as -D so we can see any HTTP errors. I would like 2 tests to run long enough for several new blocks to see if they are reported consistenly the same way and if there are any HTTP errors. Then post the full log files. 1. test with default (longpoll enabled) 2. test with --no-longpoll (disabled) This is a special test targetted at the log reporting. Regression testing with other algos is still needed. Thanks for your outstanding help testing. Title: Re: [ANN] cpuminer-opt v3.13.1.1, open source optimized multi-algo CPU miner Post by: nak333 on May 19, 2020, 11:04:27 PM I did solo mining of sha256d algo (LCC) with both version 3.13.1.1 and 3.13.2 and found a Bug. I will test again with 3.13.1.1 and will post the result. When I was doing solo mining of LCC (sha256d algo) I found this Bug report as marked in the screenshot. https://i30.servimg.com/u/f30/17/76/10/38/jdd_3_11.png Miner of both versions (v3.13.1.1 and 3.13.2) is showing this bug report. Here is the log file: https://drive.google.com/open?id=1OGFmZKF9ejfFKQtNHwgmkjl5tof-c8ka I left the miner running more than 20 minutes during solo mining, but it didn't show 5 mins summary. So, now I can say the miner of both versions (v3.13.1.1 and 3.13.2) is not showing summary during solo mining with Minotaur and sha256d algo. It only shows summary during pool mining. Now, I'm synchronizing LitecoinCash Gold (LTNCG) wallet. When syncing will be completed then will do solo mining of yespowerLTNCG algo and will post the result. LTNCG wallet synchronization is complete, but I postponed it testing, cause I got busy with some other stuffs. I will test it when Minotaur testing will complete. Did you do something different?

When I don't use `--no-longpoll` 1. The miner shows "new block report" in new format, then it shows in old format as it was doing with minotaur algo. 2. There was also Jason and HTTP error like minotaur. https://i30.servimg.com/u/f30/17/76/10/38/th/jdd-3_10.png (https://servimg.com/view/17761038/931) Log file: https://drive.google.com/open?id=183CIraMTIsTPI938NoWyL8EPCurF2yLI When I use `--no-longpoll` 1.

Title: Re: [ANN] cpuminer-opt v3.14.0, open source optimized multi-algo CPU miner Post by: nak333 on May 20, 2020, 09:27:24 PM I think time calculation is wrong during pool mining and solo mining.
When I do pool mining at rplant I get ping time 90-95ms and around 200ms at my2coins. But, v3.14.0 is showing in thousands at rplant. The ping time was okay with v3.13.2 https://i30.servimg.com/u/f30/17/76/10/38/jdd-3_15.png And I think hash calculation in 5m summary is wrong during solo mining. https://i30.servimg.com/u/f30/17/76/10/38/jdd-3_16.png https://i30.servimg.com/u/f30/17/76/10/38/jdd-3_17.png Title: Re: [ANN] cpuminer-opt v3.14.0, open source optimized multi-algo CPU miner Post by: JayDDee on May 20, 2020, 10:23:31 PM There's a lot of new stuff so I want keep things in perspective.
The high latency at rplant doesn't look like a miner problem. Take a look at the timestamp when share 238 was submitted and when it was accepted. It looks correct to me. That being said it is possible for stats to get out of sync and a high latency is one of the most obvious symptoms. Stats synchronization problems occur when a submitted share doen't get acknowledged or there is an overflow of pending acknowledgements. If you see a warning at any time that "share stats not available" it means that corruption was detected and an attempt was made to handle it and recover. You can also detect if there is corruption by auditting the data in the submit and accept logs. Do the share counts, diff, block, job all match? In any case if stats corruption is suspected all stats are unreliable but there is no other impact, shares still get submitted and accepted. Restart the miner to reset the stats. The low latency solo mining makes sense. The loopback interface doesn't use the eth card, it's just a memory copy. The timer might not have resolution under 10ms. Edit: on second though the interesting times might be related to the sheduler timeslice, which is 10 ms. The task submitting the share suspends waiting for the response. The actual reponse time may be insignificant compared to the scheduling latency which has 10 ms granularity. I had noticed a 10 ms granularity pattern in a previous log file but didn't think much more of it at the time. The zero effective hash rate in the summary is a problem, as is the still missing TTF in the new block log. I thought I removed the "Curent block is..." log, oops. Edit: I've got fixes for the 2 problems but I'll wait in case other issues are found with the release Title: Re: [ANN] cpuminer-opt v3.14.0, open source optimized multi-algo CPU miner Post by: nak333 on May 21, 2020, 11:37:33 AM I think you are right. There was a difference in the sequence of submitted and accepted blocks. Normally we see
236 Submitted 236 Accepted 237 Submitted 237 Accepted But, in the screenshot that I posted there was a delay between submitted and accepted. And I think the reason can be from my side or pool side. But, not in the miner. Now, I'm doing again pool mining at rplant with v3.14.0, it seems everything okay; latency, TTF, sequence of submitted and accepted, everything is okay. Edit: I've got fixes for the 2 problems but I'll wait in case other issues are found with the release Yes, good Idea. I saw in the pool some users are using v3.14.0 and some v3.13.1.1.

And I think there is something wrong in the calculation of hash rate. https://i30.servimg.com/u/f30/17/76/10/38/jdd-3_18.png Title: Re: [ANN] cpuminer-opt v3.14.1, open source optimized multi-algo CPU miner Post by: JayDDee on May 26, 2020, 04:48:25 PM Effective hash rate can be volatile, espcecially when solo mining. Most of the time the 5 minute
hash rate will be zero because no blocks were solved, Then you solve a block and the 5 minute hash rate is huge. It's the nature of statistics with very small samples size. I don't know why the TTF isn't displayed. It gets displayed if the reference hash rate, network difficulty and network hash rate are all non-zero. The ref hah rate and net diff are displayed elsewhere so I assume the problem is the net hash rate. This is updated by calling the getmininginfo method using RPC just prior to displaying the New Block log. Try with -D and look for a log saying getmininginfo isn't supported. Also try another coin if you can to see if it's only minotaur with that problem.

It’s hard with Minotaur because blocks don’t come that often, unlike pool mining where shares are 3-4 per minute.

It’s hard with Minotaur because blocks don’t come that often, unlike pool mining where shares are 3-4 per minute. Blocks don't come too often solo mining any coin. The 5 minute report doesn't really make sense solo mining. I'm thinking about changing it, maybe 1 hour solo, and 5 min pool. 1 Hour is still too short to be meaningful but it reduces the number of useless reports in the logs.

Thanks. I'm going to change the logic for displaying TTF solo mining. The template will always be displayed but some of the data may be invalid, with either a value of zero (zero numerator) or "NA" (zero denominator). Edit: make sure you also check the startup messages for any mention of getmininginfo. I'l wait for your test results in case more debug logging needs to be added.

The DLLs are newer versions compiled with a newer compiler. Some were taken from the mingw packages available in Ubuntu, the others were compiled from source using the same version as the host Ubuntu 20.04 package. It's the exact same procedure as before, only the base system, DLL versions and compiler version have changed. It's also notable that it works when the DLLs are compiled with a different version of GCC than the cpuminer code. This is not a simple problem. It could be a combination of factors including cpuminer, the compiler, mingw, any of the DLL packages, or the wallet. It could be Windows only or also affect Linux. Troubleshooting will be difficult. At this point I don't even have any clues as to what it might be or how to fix it. And using Windows make troubleshooting more complicated. You said previously it failed with any algo or any coin. Do you have examples? Also note if any test cases result in a different failure mode or error messages. This applies to the DLL swapping as well. Edit: did you test with only the old libcurl-4.dll? That package looks like the most likely to cause RPC errors, it's also one of only 2 that were built from source, the other is libcrypto-1_1.dll. All the others were already avaiable in the mingw packages.

I run linux, ubuntu server 18.04 on my machines. I compile locally on each machine using [./build.sh] followed by [make -j (cpu thread)] Is this the right way to do it or I should use different build options depending on the cpu? Also, is cpu-affinity a paramount value to set? I am struggling to find the right hex value to put. Is huge page important? Is cpu-priority important? All my machines are only mining, no other tasks performed. As example, two machines, exactly the same hardware, one with a i3-2130 and one with a i7-2600. Performance difference is only 22%, I can't figure out what I am doing wrong. Comparing different cpu, I achieve better performance with older core2 quad than gen2 i7 cpu. I think I am not compiling it right? Title: Re: [ANN] cpuminer-opt v3.14.3, open source optimized multi-algo CPU miner Post by: JayDDee on June 22, 2020, 11:41:19 PM The first thing you're doing wrong is overcomplicating things. Don't mess with options
until you know what you're doing. Next pay attention to the messages at startup to see what optimizations are available and used, every algo is different. If you think there's a problem post the console log.

If you think there's a problem post the console log. Sorry didn't explain myself well enough. I am not messing with options (yet) that's why I asked. When I compile I noticed that using ./build.sh gives me the best result. When miner start it shows the number of thread used and tells me SSE xxx which I assume it picks what the cpu is capable of... and set the best flags? So question one was more like.... should you use native for better general performance or set flags to be more specific in relation to cpu used? if cpu handle SSE2 and SSE4, should you "force" the compiler to set SSE4....

will use whatever it can. Title: Re: [ANN] cpuminer-opt v3.14.3, open source optimized multi-algo CPU miner Post by: franzkavka on July 05, 2020, 07:32:58 PM Hi

First you should learn about Linux command line options. There are short and long form options. -x and --proxy are the short and long forms of the same option, therefore specifying both is an error. Second you always need a mining URL, -o or --url, not both. Most pools have specific instructions on how to set required options. Don't try using a proxy until you learn the basics.

Zen 3 includes VAES for 256 bit (AVX2) vectors. This is a 2 way parallel operation backported from Intel AVX512VL. All Intel CPUs require AVX512VL and VAES to implement 256 bit parallel AES. A few bullet points: AMD will require a different CPUID configuration to distinguish Intel VAES from AMD VAES-256. A new compile architecture is required to generate the new 256 bit AES instructions. There is no performance gain, with Zen AVX2 256 bit instructions are implemented internally as 2 128 bit instructions. In cpuminer-opt all VAES is 4-way 512 bits and requires proper AVX512 support (AVX512F for 512 bit) with expected performance gains. There is nothing to be gained in cpuminer-opt by coding for 256 bit AES or recompiling the existing code for Zen3.

VAES also runs there at full 256 bit throughput. Throughput of AVX2 is easy to test. Just run a cpuminer-opt benchmark of sha256t algo using cpuminer-avx vs cpuminer-avx2. The initial Zen1 AVX2 is known to be a hack that uses 128 bits internally and there's no indication in any reviews that Zen3 is any better. But a test will confirm it. I'd appreciate if you could provide the exact feature list and do some performance testing of AVX vs AVX2 when you get yours. Regardless, there is currently no code in cpuminer-opt that does 2 way parallel hashing, with of without AES. 2 way hashing, even on Intel, doesn't provide enough performance gain to overcome the extra overhead. Edit: there may be some issues compiling for Zen3 with vaes. There is some code that assumes AVX512 is included if VAES is present. This will require a new release of cpuminer-opt. In addition, there is no compiler support for znver3 yet. The workaround is to compile with -march=znver2 until both are fixed. There are no performance implications because cpuminer-opt has no code that can take advantage of 256 bit VAES. Prebuilt Windows binaries are not affected, znver1 is used for the zen build.

Fix compile on AMD Zen3 CPUs with VAES. Force new work immediately after solving a block solo. https://github.com/JayDDee/cpuminer-opt Notes for Zen3: Zen 3 adds VAES for 256 bit vectors. Although cpuminer-opt supports VAES with 512 bit vectors it does not support 256 bit VAES. This will result in an algo's VAES optimizations not being used on Zen3. Compilers don't yet support the new znver3 architecture flag. Using znver2 is recommended when compiling from source code. It is possible to compile Zen3 with VAES by using "-march=znver2 -mvaes", but it makes no difference to cpuminer-opt. Windows users should use the cpuminer-zen build on Zen3 CPUs. Once again the question of AVX2 performance on Ryzen has surfaced, this time with a new twist: VAES. Although Zen 3 includes some significant architectural changes none of them seem to apply to the execution engine. The ease it which 256 bit VAES was added without any additional instructions suggests VAES was implemented using the existing 128 bit AES hardware. This would be consistent with the previous AVX2 implementation in Ryzen which performs 128 bit instructions internally and results in no performance increase. No actual testing was done on a Zen3 CPU, I don't have one.

VAES is full 256 bit in Zen3, I've tested it. VAES 256-bit instructions have the same latency/twice the throughput compared to 128-bit AES instructions.

Can you test AVX2 performance vs AVX? If VAES gives full 256 bit throughput I would expect AVX2 to do so as well. In previous generations of Ryzen it did not. I have to admit I'm skeptical because adding 256 bit VAES would be very simple to add and would only require a change to the instruction decoder to support the new opcode. Supporting 256 bit throughput is a more radical change and would require a redesigned vector execution unit that would also benefit AVX2. If AVX2 performance improved, it will convince me that Zen3 has an improved vector unit. Edit: I ran a test to demonstrate the poor AVX2 performance: CPU: R7-1700 OS: Ubuntu-20.04, cpuminer compiled using build-allarch.sh. Windows binaries can also be used. Benchmark test sha256t and blake2s using cpuminer-avx2 & cpuminer-avx. These algos are 100% SIMD and the AVX2 code is identical to AVX except for the vector size. Code: sha256t blake2s AVX2 should be close to double AVX. It would be nice if AMD fixed that for Zen3.

That means there would be some benefit from 256 bit VAES on Zen3. I'll look into it further. It could improve the old X algos with faster groestl, shavite and echo. RandomX is a little different. It can benefit proportionaly more with VAES512. Some of the AES sequences alternate AESENC with AESDEC so they can't be paired. VAES512 can still provide a near 2x improvement in the AES performance, whlile the pure AESENC or AESDEC sequences get near 4x. I don't know how much AES factors in the performance of RandomX as a whole.

The extra permutes would kill the advantage of 2 way parallel AES, but yes it can be done, 4 way parallel (avx512) might overcome the penalty. I looked at RandomX VAES a while ago but couldn't figure out how to enable AVX512 to compile with cmake. I'm not good with c++ either. I'm playing with AVX2+VAES on my Icelake laptop, it looks like x17 with get a 7% boost by using VAES for groestl, Shavite & Echo. I assume similar for Zen3. If things work out the next release may include a zen3 build with VAES in addition to AVX2 & SHA.

I definitely appreciate the work though, I have been using cpuminer-opt off and on for years now The short answer is any algo derivative of x11 or containing parts of x11, otherwise known as sha3 based. The irony is that the algos that can use AVX512 etc can't compete with GPUs. The long answer requires searching through the code of each algo. I'm not sure what you mean by no longer supported. I focus more on newer CPUs and algos that are still mineable with a CPU (although difficult for some) but all algos are still supported.

That depends on a couple of things (at least): 1. CPU type. Generally, Ryzen cpus will be a better choice for mining these days, especially those with higher core counts and larger L3 cache. 2. Your strategy. You can mine a coin believing it will moon one day in the future. Then you might not mind it not returning more than a few cents a day now. You can let the miner do its work and forget about it until the day the coin moons and then rake in the profits selling. Or, you can spend a lot of time researching the coin of the day and mine it short term to see if that will earn you a quick buck. I think XMR has potential to go higher in price and am mining it.

Do not mine scrypt with a cpu... not even a GPU is worthwhile. Basically it's so slow it never finds a share it can submit. Use another algorithm for the other coins, specifically the CPU coins. At least you can get something for your effort there.

That might have been obvious by the slower pace of new
releases and less content in each one I've achieved everything I wanted to from a technical standpoint. All of the suitable algorithms have been optimized to support AVX512, SHA and VAES. This brings support to CPUs that haven't even been released yet. Adding new algorithms was never part of my plan but many were easy to integrate into the cpuminer design. Tha's no longer the case. Most new algorithms are written differently and don't fit well with cpuminer. Many use c++ and cmake while cpuminer uses c and automake. The number of different algorithms has increased with more algorithms being used by only one coin making them more work to support. Coins are frequently changing algorithms making even more work to support. The days of an all in one cpu miner are coming to an end. Custom miners are required for many coins. I wouldn't be able to keep up even if I wanted to. I have 1 more planned release with a few minor code tweaks and some cleanup, but nothing realy new. After that it's bug fixes only, which hopefully will be few. I have no plans of going anywhere and I may get bored, so who knows.

Added verthash algorithm. It's slow but it works. https://github.com/JayDDee/cpuminer-opt/releases The following is superseded by v3.16.1. but may be available for download elsewehere, YMMV. For cpuminer-opt the verthash data file must be named verthash.dat and located in the same directory as the cpuminer executable. A Linux symlink works. The verthash data file must be obtained seperately. If you already use VerthashMiner you can simply copy or link the existing data file to the cpuminer directory, using the required name. Otherwise it may be created using https://github.com/CryptoGraphics/VerthashMiner/releases following the instructions. A GPU is not necessary to create the file. The same data file can be used by both cpuminer and VerthashMiner simultaneously. Launching cpuminer to mine verthash is the same as any other algorithm, no extra options are required.

https://github.com/JayDDee/cpuminer-opt/releases New options for verthash: --data-file to specify the name, and optionally the path, of the verthash data file, default is "verthash.dat" in the current directory. --verify to perform the data file integrity check at startup, default is not to verify data file integrity. Support for creation of default verthash data file if: 1) --data-file option is not used, 2) no default data file is found in the current directory, and, 3) --verify option is used. More detailed logs related to verthash data file. Small verthash performance improvement. Fixed detection of corrupt stats caused by networking issues. Quickstart for Verthash: First time mining verthash or don't have a Verthash data file: --algo verthash --verify --url ... Verthash data file already exists: --algo verthash --data-file /path/to/verthash.dat --url ... See verthash-help.txt for more details.

My i9-9940x slows from 4.3 GHz (all cores) to 3.5 when running AVX512. I've been trying to vectorize verthash and AVX512 is slower than AVX2. I presume the significantly lower clock rate slows down data file access, negating any gains from code optimization. I also presume eth would have the same issues with the DAG. I'm also not aware of any usable CPU miners for Eth.

Verthash: midstate prehash optimization for all architectures. Verthash: AVX2 optimization. GBT: added support for Bech32 addresses, untested. Linux: added CPU frequency to benchmark log. Fixed integer overflow in time calculations. For solo mining with getblocktemplate Bech32 addressing is not tested and segwit is uncertain. One, the other, or both may not work. Testing is welcome. Questions can be discussed here or by opening an issue with git. I'll do my best but I can't make any promises. Please add -D command line option if trying Bech32 or segwit.

Usually the coin developpers should publish the POW specifications including parameters. A pool that supports the coin will often have mining instructions for the coins it supports which should include parameters if they are required. However, I'm concerned about the reject reason in this case. I would expect "invalid share" if the parameters were incorrect. But the reason suggests a nonce size issue, not a parameter issue. The reason also includes the coin's symbol suggesting something specific to RES. I've never seen this error before, there may be something unique about the implementation of the stratum protocol used by this coin that cpuminer-opt doesn't support. If so I don't know what it is. If the coin has a thread in the ANN section I suggest asking there. You could also ask rplant, he should know. His pool, and presumably his miner, support it. You could also add -D to the command line and note the log messages at startup related to stratum, That may provide a clue.

and will be fixed in the next release. The only thing that seems certain is there are 2 problems. First is the reject reason.

I've got a cooler master sub-zero system (thermoelectric cooling system) from newegg showing up in a few days... will put that in the system and try avx512 again. https://www.newegg.com/cooler-master-liquid-cooling-system-masterliquid-ml360-sub-zero/p/N82E16835103310?Item=N82E16835103310 Rocketlake is going to be hot, it uses 14nm for an architecture designed for 10nm. It added AVX512 & SHA but had to leave out VAES and the top end 10 core model. Performance will depend on the algo and the AVX512 clock penalty, and possibly thermal throttling. the tec cooler was a failure. Great temps if CPU idle or running single core or gaming... complete bust for mining. result were worse than the AIO 360. thermal throttling with avx2 (i.e. 100C)... didn't even try avx512. I'm going to go full custom water loop next attempt. Phanteks Enthoo Prime case with a 420 radiator (or a 480) push-pull configuration on top of case with 4 120mm fans on the bottom of case to suck cold air inand maybe and additional two 240 radiators, one on the side and one on the front. Title: Re: [ANN] cpuminer-opt v3.16.2, open source optimized multi-algo CPU miner Post by: paperoga on May 04, 2021, 12:28:53 PM Some weird things happening on algo m7m. Miner compiled locally with proper settings. Miner is running via a local proxy set in another machine.
If there is a disconnection between pool and proxy, this happens: If I shut miner down and restart it, all goes well again. First time i see something like this. Any idea? I can troubleshoot if you need me to. I have several machines exactly the same to test if need be. I set roundrobin very low on purpose on the proxy to test it and can replicate it. It doesn't happen on 3.12 or 3.14 versions. I recompiled a fresh version of latest, tried 4 times, once it recovered as normal, 3 times it failed. ~~~ few friends told me I will get bored after retirement...

Title: Re: [ANN] cpuminer-opt v3.16.3, open source optimized multi-algo CPU miner Post by: chrysophylax on June 01, 2021, 01:13:38 PM I believe its 64 threads, its a 16 core AMD Opteron 6378 CPU x4 with 256GB of RAM This only happens with 'Threading Tech' applied ... Opteron (as with any CPU that uses HyperThreading Type of technology) is classically using only the cores allotted, but with HyperThreading Tech enabled, it uses the SAME cores but different time slices. Which means you have 64 Physical Cores (if this machine is a Quad CPU Machine) and another 64 'SoftWare' Cores - making 128 Cores in total as far as the OS can 'see'. That is IF this is happening here with this machine. So even though it is showing only 50% usage of all 'SoftWare' Cores, the physical cores are actually being used to close to full capacity. You may get some increase in hashing, but I would assume very little if you set your miner thread count at 128. You can test it and see, it can't really hurt the Physical CPU's themselves, but the whole OS may slow down considerably so be prepared to wait for things to happen when you click Wink These Opteron CPU's were incredible in their day.

A SMT core is actually 1 1/2 CPU cores. It has 2 register files to manage 2 threads but only one set of shared execution units. Simply put 2 threads can run simultaneously if they don't need the same execution units. For example one thread could do an FP operation while the other is doing integer. The problem here is it's a multi socket system. They typically aren't used as a monolithic system, often partitioned by the OS to avoid crossing CPU boundaries to access resources. In effect it looks like a bunch of virtual machines and the miner is likely only using one. Multi-CPU support has never been properly tested for mining and likely requires significant system admin skills to understand how to fully use it. It starts with providing clear and concise technical information about what the user, miner, and OS are doing.

Try different thread/affinity configurations to find the sweet spot, half the number of threads with alternating affinity (0x55555555) seems to work best in many cases.

Shame, cos it's a great coin to mine, but the team haven't bothered optimising the miners for nearly 12 months. I'm sure yours would be much better :) It looks like it's pure AES and is already using AES_NI instructions. VAES is possible but that would be limited to 2 ways on Ryzen 5xxx. 4 way VAES is only available on a few Intel laptop CPUs with VAES & AVX512. It's hard to estimate the gain due to the larger data load, extra data manipulation and lower clock rate. Theoretically 2 ways would be in the range of 1.5x and 4 ways would around 2.5x. If it's only a matter of importing the Haraka hash function it could be a trivial addition. I'll give it a quick test, but if it doesn't work as is I'll give up because I wouldn't know where to start debugging. Edit: It won't work, the stratum protocol is different.

See the first post in this thread for download links. Release notes: Complete rewrite of Scrypt code, optimized for large N factor (scryptn2): - AVX512 & SHA support for SHA256, AVX512 has priority, - up to 50% increase in hashrate, - memory requirements reduced 30-60% depending on CPU architecture, - memory usage displayed at startup, - scrypt, default N=1024 (LTC), will likely perform slower. Improved stale share detection and handling for Scrypt with large N factor: - abort and discard partially computed hash when new work is detected, - quicker response to new job, less time wasted mining stale job. Improved stale share handling for all algorithms: - report possible stale share when new work received with a previously submitted share still pending, - when new work is detected report the submission of an already completed, otherwise valid, but likely stale, share, - fixed incorrect block height in stale share log. Small performance improvements to sha, bmw, cube & hamsi for AVX512 & AVX2. When stratum disconnects miner threads go to idle until reconnected. Colour changes to some logs. Some low level function name changes for clarity and consistency. The reference hashrate in the summary log and the benchmark total hashrate are now the mean hashrate for the session. Aditional details, tips and suggested testing: A lot has changed so lot of testing would be helpful. The first tip is for Ryzen users and scryptn2. Ryzen can mine scryptn2 using SHA or AVX2. The current default for is to use SHA. Users may want to try an AVX2 build to see if that gets better performance. In future release I may change the default to use AVX2. For Rocket lake CPUs the default is to use AVX512. Hash rate reporting has significant changes. The reference hash rate in the summary may be slghtly lower but it will be more accurate and directly comparable with the effective hash rate for the session. The longer the session the more they converge. The previous hash rate calculation is still reported in the TTF of the New Block log for comparison. The old way didn't account for overhead such as the stratum thread or other applications or system processes running. The old way is also used for thread hash rates displayed with the --hash-meter option. The differences also show why miner wars fighting over who has a slightly faster hash rate is a waste of time. The only thing that matters is what the pool sees. Changes were made to stale share detection and handling, in particular for scryptn2. It's notorious for stale shares for the simple reason it takes nearly a full second to calculate hash. I've found the processing bottlenecks and placed checkpints at strategic places to check for new jobs that will cause the current hash to be aborted and work will begin with the new job. This should reduce the number of stale shares. In addition some new logs are introduced related to stale shares that apply to all aggos. One is output when a new job is received with a submitted share still pending a response. In this situation the share may be accepted or rejected, there's no way to know it it arrived at the server in time. There is nothing that the miner can do about this except report it. The other new log is displayed when new work is deteced but a fresh valid share is in hand. All the hard work has already been done so it might as well be submitted. These have a higher likelyhood of being stale unless the pool offers a grace period where it accepts late shares. I have seen shares accepted after this log so I'm hesitant to discard them and possibly waste a perfectly good share for the sake of keeping stale numbers low. Scryptn2 now uses much less memory. In addition to organic improvements to the code it may be possible for CPUs that were previously limited in the number of threads they could run to be able to run more threads and possibly increase performance further. Please test and report your results.

I'm not sure I understand your question but if you want to make a donation the simplest way is a direct BTC transaction to the donation address displayed at miner startup. You may also direct your mining rewards to the donation address if you prefer. Only BTC donations are supported at this time. cpuminer-opt has no fee of any kind therefore has no built in mechanism for collecting one. Donations are purely voluntary and made at the discretion of the users.

It looks like Alder Lake desktop CPUs won't have AVX512 or VAES which is a step backward for Intel and puts them behind AMD. which supports 256 bit VAES on zen3. Alder Lake will use a big-little architecture with a combination of big powerfull cores with smaller more efficient cores. AVX512 is being disabled on the big cores to provide a consistent instruction set with the small cores which don't support it. If AMD adds AVX512 on Zen4 they will go 2 steps ahead of Intel, just in architecture. Alder Lake will finally ditch the 14nm process but Zen4 will likely involve another die shrink keeping AMD ahead of Intel in that department as well. If Zen4 also includes PCIe5 and DDR5 it will be clearly ahead or equal with Intel in every department. That hasn't happened since AMD was first with 64 bit desktop CPUs, Debian packages still use the amd64 name. Zen4 could also have some surprises like another boost in core count or bigger cache. I really don't see a fit for big-little architecture. On the desktop the small cores are pretty useless and on a laptop I prefer more smaller more efficient cores than the big cores that are either sitting idle or draining the battery. I don't think I'll be buying any Intel CPUs for a while.

I couldn't find anything relevant with Google, just coins claiming they have no founder reward. Yet I don't how the miner would be involved with the founder reward, It has no knowledge of the block reward or how it's shared and such knowledge would not be of any use anyway. It seems an intentional way to limit mining. If that's the case I'm not interested. I'm also interested in any coin with a founder reward. The founders can afford to pay developpers, they won't get aything free from me.

More speed for scrypt: - additional scryptn2 optimizations for all CPU architectures, - AVX2 is now used by default on CPUS with SHA but not AVX512, - scrypt:1024 performance lost in v3.18.0 is restored, - AVX512 & AVX2 improvements to scrypt:1024. Big speedup for SwiFFTx AVX2 & SSE4.1: x22i +55%, x25x +22%. Issue #337: fixed a problem that could display negative stats values in the first summary report if the report was forced prematurely due to a stratum diff change. The stats will still be invalid but should display zeros. Although, in my testing on a i5-2400, scryptn2 AVX is faster than v3.18.0 it's still slower than 3.17.1. I have no idea why. It uses essentially the same code for AVX512, AVX2, AVX & SSE4.2. When I do a benchmark on a bigger newer CPU there is not a significant drop from AVX2 to AVX, in fact less than the lost AVX performance from v3.17.1 to v3.18.0. I can't explain this. If any users have AVX CPUs it would be appreciated if you could run a quick test to either confirm or contradict by results. Either way would be a step forward to understanding this mystery. Title: Re: [ANN] cpuminer-opt v3.18.2, open source optimized multi-algo CPU miner Post by: JayDDee on November 09, 2021, 08:04:19 PM Here's an arcticle about enabling AVX512 [& VAES] on Alderlake CPUs running Linux.
Unfortunately there were no details about compiling. "Official" Alderlake should be compatible with, ironically, Zen1. With AVX512 [& VAES] it should be compatible with https://www.phoronix.com/scan.php?page=article&item=alder-lake-avx512&num=1 In a seperate arcticle it was mentioned that Intel has yet to supply Thread Director patches for the Linux kernel. Any sharing of user experience with Alderlake would be appreciated. "Tom" also did a comparison test of the top end Alderlake with Ryzen 5900x & 5950X. Although Alderlake won overall in Gaming performance using Win11 with Alderlake optimizations, Ryzen had better multithreaded performance using less power. Edit: corrected for VAES which is also available but not mentioned in the arcticle.

Linux: Faster verthash (+25%), scryptn2 (+2%) when huge pages are available. Small speed up for Hamsi AVX2 & AVX512, Keccak AVX512. Download links are in the first post of this thread, verify links before clicking on them. Additional notes about huge pages: Huge pages is an advanced OS feature that has pros and cons. Users should be familiar with the issues before enabling huge pages at the OS level. Reserving too many huge pages can destabilize the system. cpuminer-opt will automatically use 2 MB huge pages on Linux for Verthash and Scryptn2 if they are available. The miner does not reserve huge pages, it will only use what has been reserved by the OS. There is no need to run the miner as root to use huge pages. Confirmation of huge page use can be done in 2 ways: cpuminer logging which may require --debug, or by using the proc file system to monitor huge page usage system wide.

Changing optimization level to -O1 solved the problem and it compiled successfully. I never got mingw/msys2 working from a Windows host but if you've gotten this far it's worth pursuing. If you have git an issue would be appropriate for tracking. It compiles ok with gcc 11.2.0 on Ubuntu-21.10 but I don't have mingw setup for that. I currently use gcc 9.3.0 in Ubuntu 20.04 to build the Windows binaries as documentd on the Wiki. It's odd that it would compile depending on compiler optimizations, also that it's old code. If I can identify what code is causing it there might be a better way to write it even if the bug isn't obvious. be a compiler bug. Edit: sph_jh doesn't include any Windows compatibility code so mingw compiles the same source code as Linux. Edit: Not needed anymore: Relevant warnings, if any, from the -O1 compile might also be useful in figuring out why this switch makes a difference. using a full Linux installation, VM or separate PC, is quite cumbersome. Update: I got msys2 installed and was able to get to the same point as you. The good news is if the compiler can get past sph_jh.c it will compile successfully. I haven't tried running it yet. The bad news is 5 lines of code need to be commented out: Code: #define Sb(x0, x1, x2, x3, c) do { \This compiles but if any one line is uncommented it will fail. I have no idea what the problem is. The code is very old and stable and hasn't had any problems before. GCC 11.2 works on Ubuntu-21.10 native and mingw. It works with msys2 with -O1 but not -O3. The compiler can't provide a reason for the error. The main difference between the Ubuntu mingw and Windows mingw, other than the OS itself, is msys2. I can't make sense of this, could be a compiler bug, msys2 bug, some incompatibility? I couldn't find another version of GCC in the package repo but maybe an older version of msys2 might not have this bug. It's still a lot farther than I've gotten before with msys2. Update2: It appears the compiled cpuminer.exe will only run from the msys2 environment. There are 4 missing dll's when running directly from Windows, some are built by hand for the existing Windows package which means the same would have to be done to make the msys2 build portable. So it doesn't look suitable for portability, maybe just for Windows geeks that want to compile themselves. Assuming the compile issue can be solved, there is the question of performance. There's no point in testing performance with different compiler optimizations or butchered code. Using cygwin the perfomance is lower than the current mingw build package. I believe msys2 uses some components from cygwin so it may also be slower. Title: Re: [ANN] cpuminer-opt v3.19.4, open source optimized multi-algo CPU miner Post by: frozen80 on January 14, 2022, 01:26:58 PM You were right, it is a compiler bug!
The problem is a flag in -O2 level that is -ftree-vrp and the default values of its parameters. We can keep -O3 and add --param=evrp-mode=legacy. From my understanding this param will instruct how the flag -ftree-vrp will perform. The default value for this param is ranger: Code: --param=evrp-mode=[legacy|ranger|legacy-first|ranger-first] default is "ranger" Code: CFLAGS="-O3 --param=evrp-mode=legacy -march=native -maes -Wall" Aside from this, you are right about the resulting binary. It's working only in msys2 environment. It might work outside msys2 too, if we provide the path to the DLLs files. It's just another way of doing it, and if it's possible, why not!

I did a quick performance test and it's equal to the existing Windows package. The test was done on a VM so I'll have to try it on real HW. I may have found a way to make portable https://stackoverflow.com/questions/6951938/libgmp-10-dll-is-missing. All the dll's reported missing are there, but I haven't tried it yet. it's better than building them. Edit: I've updated the compile instructions for Windows on the Wiki. Give it a test run if you like and let me know of issues. I suspect portability is still an issue with the MSYS2 build. Only 4 DLLs were missing on a system where MSYS2 was installed, there may be others on a system without MSYS2. Edit2: I ran through the new procedure on an i7-6700K Win10 and had no problems. The executable ran in both the MSYS2 environment and a Windows comand prompt with the environment variable set. It looks pretty solid. I won't pursue using MSYS2 for the portable binaries package at this time. I'd still have to package dll's with it, and I'd have to setup a Windows virtual machine for package building. It would end up being more work for me. The existing Ubuntu based mingw environment is already setup and very simple to use. When the time comes to upgrade my development system I may reconsider. I'm also going to have to do a pass on fixing compiler warnings. GCC-11 is flagging a bunch of string overflows that should be addressed.

I think users should be also informed to follow the instructions on the msys2 website to update the base packages and install some tools for compiling(just in case they overlook these three steps): Code: pacman -Syu I'll have to think about that. Those steps are part of the installatin procedure, IMO, and I don't want to duplicate it. There may be some ambiguity that installation means only running the installer file. I can clarify that to instruct to do the the post-install setup up to the end except where it says to close the MSYS2 MSYS window. How about something like? Run the installer and perform the post intall setup to update the packages and install the mingw toolchain. Leave the MSYS2 MSYS window open for further package installations in the next step. Update: I've updated the instuctions, they should be clearer in what's involved in the MSYS2 installation procedure. I also removed the option to compile without CPU groups. Since CPU groups are supported from Win7 and MSYS2 requires minimum Win7 there is no situation where it's not supported.

https://bitcointalk.org/index.php?topic=5383533.0 Title: Re: [ANN] cpuminer-opt v3.19.5, open source optimized multi-algo CPU miner Post by: JayDDee on January 31, 2022, 04:28:24 AM cpuminer-opt-3.19.5 includes an enhanced stratum-keepalive feature to prevent lost shares.
TLDR stop here. There really is no actual stratum-keepalive, it's a hack as described below. It doesn't really keep the connection alive but it prevents the negative effects of the pool server timing out if no shares are submitted for a long time. CPU miners are challenged by pools that set a minimum difficulty too high for CPUs to find shares regularly. After around 5 minutes with no shares submitted the pool will drop the connection but not notify the miner. Often the miner detects the dropped connection only when submitting a share. This results in a lost share and is noted in the summary log as stratum errors and share count mismatches. Every mismatch in the counter represents a lost share. When shares are so rare this is a big loss. The first stratum-keepalive was a futile attempt to send a harmless message to the server in the hope it would prevent the timeout. It was also convenient that the protocol defines a specific method "mining.suggest-difficulty" which perfectly suits the situation. Unfortunately this was not successful. Pools not only ignore the request for lower difficulty it doesn't reset the's pool timeout either. In effect it's useless. However, it will remain in case pools decide to support the method some time in the future. The enhanced stratum-keepalive goes one step further, it will pre-emptively reset the stratum connection before the pool times out and closes it. This will prevent the miner from sending a share over a dead connection. It also eliminates wasted time hashing with a dead connection even if no share is found. The suggest difficulty method is sent after 3 minutes with no shares submitted and the pre-emptive reset is done after 4 minutes with still no shares submitted. Timing is not precise but the reset is usually done before 5 minutes. The option is disabled by default and can be enabled with --stratum-keepalive. There should be no harm in using even if timeouts aren't a problem.

Oh my lord....I must have had way too many txt documents up all at once, because I ended up successfully creating the cpu miner that I think is Wyvern or whatever Raptoreum has up on their website. I had the READ ME of cpuminer-opt up and I was trying to figure that one out as well, so obviously my brain is a wee bit addled. I just took a look and it does say right there in the READ ME doc that the gr algo isn't supported anymore.The miner that's the object of this thread (cpuminer-opt) looks much more interesting now that I've begun to understand the workings of it. I'll let the RTM miner run a little longer then try the other. Thanks for catching my boo-boo. I still give mucho props to JayDDee; that wasn't a mistake. Title: Re: [ANN] cpuminer-opt v3.19.6, open source optimized multi-algo CPU miner Post by: JayDDee on March 19, 2022, 01:54:58 PM One of my goals was to make the miner somewhat modular to make it easier to add (or remove) algos.
Unfortunately it doesn't work with most of the newer miners/algos that use cmake & c++. Also with most new coins choosing new unique algos the work to support new coins has increased. As a result those new coins that can use the cpuminer mining architecture fork the miner to build their own. My only disappointment with that approach is those who take open source code, close it, then charge a fee. Thanks for the kind words.

The CPUminer-Opt docs say that the "minotaur" algo is supported. Is there support for the "minotaurX" algo, or could it be added and optimized? Currently, the "minotaurX" algo is rated high in profitability at ZergPool. --scryptr Title: Re: [ANN] cpuminer-opt v3.19.8, open source optimized multi-algo CPU miner Post by: JayDDee on June 12, 2022, 03:13:36 AM It's a long story why I didn't support minotaurx that has mostly to do with how quickly minotaur was abandoned by the same people
who asked me to support it, then asked me to support minotaurx. I'm no one's unpaid employee. Minotaurx is essentially a slow X16R (like Hex) + Yespower yet it pays less per hash than Yespower alone so I don't get where this high rating came from. Title: Re: [ANN] cpuminer-opt v3.19.8, open source optimized multi-algo CPU miner Post by: scryptr on June 12, 2022, 06:38:51 AM MINOTAURX --
First, thank you for the rapid response. MinotaurX is one of the top 5 in profitability at ZergPool. As I type this, it is #2, with 3 coins being served. Check it out. The code is already out there, you are the coder with assembly skills. --scryptr Title: Re: [ANN] cpuminer-opt v3.19.8, open source optimized multi-algo CPU miner Post by: JayDDee on June 13, 2022, 04:05:16 PM MinotaurX is one of the top 5 in profitability at ZergPool. As I type this, it is #2, with 3 coins being served. Profitability is not realy the issue at this point, even if it could be sustained. The killer is yespower, when it's present it dominates everything else. There's no point in optimizing the X16R part because it won't help the overall performance. Many of the X16R optimizations can't be applied to this implementation anyway. There's also a unique GBT protocol change that would be difficult to test. I believe there are at least 2 optimized CPU miners that support minotaurx already. They likely already have any optimizations I could add. I'm simply not interested.

The big addition to 7000 is AVX512 but I haven't found any specifics about what AVX512 extensions are included. VNNI is the only one I've seen mentioned because it's for AI and AI Is hot right now, but of no use in cpuminer-opt. I assume DQ, BW & VL are included to be compatible with the Intel Skylake-AVX-512 I use as a baseline reference. The first thing would be to confirm the AVX512-SHA-VAES Windows build works on Ryzen 7000, Also confirm build options for GCC (Linux or Windows) becaue zen4 isn't supported as of GCC-12. I've added some notes to the Wiki: https://github.com/JayDDee/cpuminer-opt/wiki/Compiling-from-source I have read that Ryzen's implementation of AVX512 is "double pumped" which I assume is the same as the AVX2 implementation from zen1. This will limit the gains of using larger vectors as was the case with Zen1 AVX2. The reason given this time was to reduce the clock penalty of using larger vectors. It would be interesting to compare with and without AVX512. In some cases AVX2 may be faster. The cache is larger so cache dependant algos may support more threads before cache overflow starts reducing performance. Also keep a close eye on temperatures, I have read that zen4 is difficult to cool. Edit: additional request from a Linux user: cat /pro/cpuinfo to get the list of AVX512 extensions.

Some algos of interest for performance testing: myg-gr, groestl: heavy VAES, some AVX512 allium: heavy AVX512, some VAES skein2, blake2b, keccak, sha256t: pure AVX512 SHA is not used much because parallel Nway is always faster. myr-gr uses some AVX2 with the AVX512 build, Groestl is pure VAES+AVX512. sha256d is also pure AVX512 but the AVX2 version uses Pooler ASM code so it can't be used for comparison.

I plan on picking up a 7950 or 7900 within the next couple of days. Are there any results you want to see? Thanks for the offer. I hope to get one before the end of the year. The big addition to 7000 is AVX512 but I haven't found any specifics about what AVX512 extensions are included. VNNI is the only one I've seen mentioned because it's for AI and AI Is hot right now, but of no use in cpuminer-opt. I assume DQ, BW & VL are included to be compatible with the Intel Skylake-AVX-512 I use as a baseline reference. The first thing would be to confirm the AVX512-SHA-VAES Windows build works on Ryzen 7000, Also confirm build options for GCC (Linux or Windows) becaue zen4 isn't supported as of GCC-12. I've added some notes to the Wiki: https://github.com/JayDDee/cpuminer-opt/wiki/Compiling-from-source I have read that Ryzen's implementation of AVX512 is "double pumped" which I assume is the same as the AVX2 implementation from zen1. This will limit the gains of using larger vectors as was the case with Zen1 AVX2. The reason given this time was to reduce the clock penalty of using larger vectors. It would be interesting to compare with and without AVX512. In some cases AVX2 may be faster. The cache is larger so cache dependant algos may support more threads before cache overflow starts reducing performance. Also keep a close eye on temperatures, I have read that zen4 is difficult to cool. Edit: additional request from a Linux user: cat /pro/cpuinfo to get the list of AVX512 extensions. Hi Mate ...

I haven't had the same problem with intel... intel i can disable the igpu in the bios. even with the 5x00 series amd igpu i can disable the igpu, just not with the 7xxx igpu. one thing i've noticed with the amd 7xxx series igpu, is that if you have a discrete AMD gpu (6xxx/5xxx gpu) is that the igpu attaches itself to the discrete gpu and runs in a hybrid mode. doesn't happen with nvidia disrete gpu, though the amd igpu will still show up on af and control panel. I'm sure eventually AMD and the board manufacturers will allow me to disable it.

A number of things are converging that require some decisions to be made. After 7 years I think I've squeezed about as much juice from cpuminer as I can. I have a couple more small optimisations so there will be, at least, one more release. Another factor is I'm planning to upgrade my main system, where I build the Windows binaries package. That means I will need to rebuild the mingw environment for Ubuntu-22.04 from scratch or build a Ubuntu-20.04 VM and port the existing environment to it. Without a plan for more development it's hard to get motivated to do the extra work. There is also now a more friendly way for Windows users to compile their own, and with better tuning for their CPU. cpuminer-opt's usefulness is diminishing fast, and falling further behind GPUs. CPUs can't provide large generational performance increases that GPUs do. The crypto bear market isn't helping. The mining environement has changed, a multi-algo miner is no longer feasible. Most new coins use their own custom algo now. Most new miners are also written in C++ and use cmake so they are very difficult to integrate with the cpuminer architecture which is written all in C and uses autoconf. There is also the bloating issue with trying to support many dissimilar algorithms. I'm not sure what I'll do or when but it seems the end is in sight.

an open source cpu miner. The binary releases don't match the posted source code and could be infested with malware. It seems ironic that in the worst mining market in years this would be a growing problem. This new problem goes beyond the frequent practice of closing the source code to collect a fee, it's downright fraud. It misleads the user into thinking they are downloading a binary built from open source. As always stay alert. cpuminer-opt never needs to run with elevated priviledges, doing so with any untrusted miner exposes the system to attack. Only use trusted software.

Features include: double the number of SIMD registers, mask registers to support masking operations, bit rotation & ternary logic instructions will be implemented on E-cores but 512 bit wide vectors won't. 512 bit vectors (AVX10-512) will only exist on P-cores and only if no E-cores are present. Hybrid CPUs will use AVX10-256 on both E-cores and P-cores. Version 1: AVX10.1-512, a rebranding of AVX512 with support for 512, 256 & 128 bit vectors, is scheduled to be included on Granite Rapids Xeon CPUs, P-core only, in 2024. Version 2, AVX10.2-256 will come later and support 256 & 128 bit vectors is expected on Clearwater Forest Xeon E-cores in 2025. AVX10-512 is binary compatible with AVX512 and software built for AVX512 should run fine on AVX10-512 CPUs. AVX10-256 should be able to run software built for AVX2 but will not have the AVX512VL features. Recompiling for AVX10 will enable most features but some source code tweaks may be needed to targeted code to get the best performance. AVX10 is not backward compatible with existing CPUs, they must continue to use AVX512 or AVX2 software builds as appropriate. AVX10 could be a non issue for AMD because Zen4 & Zen4c already support AVX512. A Zen based hybrid CPU, should AMD decide to build one, would have a unified ISA so the P-cores wouldn't need to be gimped because of the E-cores. Zen4 is missing a couple of the latest AVX512 extensions that are to be included in AVX10.1. Assuming those extensions are forthcoming future Zen CPU architectures will implicitly have AVX10.1-512 support using AVX512 flags without formally supporting AVX10. There is no official word from AMD yet. It looks like Intel is giving up on AVX512, future Xeon server CPUs appear to E-core based to increase thead count. Intel also announced the APX extension, a significant improvement to the base X86_64 ISA by doubling the number of GPRs and supporting 3 operand instruction encoding. Existing SSE* and AVX* instructions will also gain 3 op encoding. Intel didn't mention when APX would become available but coincident with AVX10 would be a reasonable assumption. No source code changes are required to take adavantage of this feature, recompiling with APX on an APX capable CPU is all that is needed. GCC support for AVX10 version 1 is expected in gcc-14 with support for the following: -march=graniterapids includes "-mavx10.1-512" -mavx10.1 default, same as "-mavx10.1-256" -mavx10.1-256 AVX512 without 512 bit vectors, no supported CPUs until AVX10.2 -mavx10.1-512 equivalent of existing AVX512 superset Title: Re: [ANN] cpuminer-opt v3.22.3, open source optimized multi-algo x86_64 CPU miner Post by: andy2572192561 on August 22, 2023, 01:12:11 AM This is the home of cpuminer-opt, the optimized x86_64 CPU miner.

A x86_64 architecture CPU with a minimum of SSE2 support. This includes Intel Core2 and newer and AMD equivalents. AES optimizations require a CPU with AES_NI including Intel Westmere and newer and AMD equivalents. Further optimizations are available on some algorithms for CPUs with AVX (Sandybridge), AVX2 (Haswell, Zen1), AVX512 (Rocketlake, Skylake-X, Zen4), SHA (Zen1, Rocketlake), and VAES (Zen3, Rocketlake). 32 bit Intel and AMD CPUs are not supported. Other architectures such as ARM, Raspberry Pi, RISC-V, etc, are not supported. Mobile devices like lapotop computers are not recommended because they aren't designed for continuous full load. 2. 64 bit Linux OS. Debian and Fedora based distributions including Ubuntu, Mint, RHEL and clones are known to work and have all dependencies in their repositories. Others may work but may require more effort. Windows 7 or newer 64 bits is supported using the pre-compiled binaries package or may be compiled from source using MinGW. FreeBSD is not actively tested but should work, YMMV. Apple and Android operating systems are not supported. Older CPUs, other architectures and operating systems may be supported by TPruvot's cpuminer-multi. Security warning Cryptocurrency miners often flagged as malware by antivirus programs. This is usually a false positive, they are flagged simply because of what they are. However, some malware has been spread using the cover that miners are known to be subject to false positives. Always be on alert. The source code of cpuminer-opt is open for anyone to inspect. If you don't trust the software don't download it. Some cryptographic code has been taken from trusted sources but has been modified for speed at the expense of accepted security practices. This code should not be imported into applications where secure cryptography is required. Errata: Old algorithms that are rarely used or are too difficult to mine with a CPU will not get the latest optimizations. Cryptonight and variants are no longer supported, use other miners. Hodl requires a CPU with AES. Donations cpuminer-opt has no fees of any kind but donations are accepted. BTC: 12tdvfF7KmAsihBXQXynT6E6th2c2pByTT Hello!

TLDR: nothing for at least a year. SHA512: this is an enhancement to SHA that adds support for SHA-512. SHA512 is expected on Intel Lunar Lake & Arrow Lake CPUs in 2024. AMD availability is unknown, Zen5 would be optimistic. GCC-13 is required to build with SHA512. SHA-512 is used by m7m, minotaurx as well as the x16 and x17 series including hmq1725. Performance is expected to exceed AVX512 8 way parallel SHA512. SHA512 needs new code. SM3 & SM4: SM3 was only used by a couple of short lived algos, SM4 is not used at all in crypto AFAIK. They are of no interest. AVX10: is a complete redesign of the AVX architecture to replace AVX2 & AVX512. For CPUs with 512 bit vector support it means very little. It's most significant impact is on CPU limited to 256 bit vectors. AVX10 adds support for AVX512 features & instructions limited to 256 bits (E-cores), essentially it's AVX512VL without AVX512F. It will supported by GCC no earlier than GCC-14. AVX10, specifically AVX10-512 will first be avalable on Intel Granite Rapids which will support 512 bit vector length so it's just a rebranding of AVX512. The first real benefit of AVX10 is AVX10-256 which adds bit rotation, opmasks, and more vector registers. Availability of AVX10-256 has not been announced. AVX10 is not an issue for AMD as all new CPUs support AVX512 already. Minor coding changes are required to support AVX10-256, AVX10-512 requires no code changes or rebuilding, AVX512 build will work as is. APX: this will help all non-vector code by doubling the number of general purpose registers and supporting 3 operand instruction encoding that will eliminate the need for many register moves. Nothing is known about availability but it was announced by Intel at the same time as AVX10. APX will also improve AMD CPU performance and are expected to adopt it. No coding changes are required, just rebuilding with a supported compiler. The current system used to build the Windows binaries package will not support any of these new features because it's based on GCC-9. Providing Windows binaries with the new features will require a new build environment with a supported compiler and OS.

This is an old post from "oink70", who optimized Monkins' Verushash CCminer: "Oink70 (2 yr. ago on Reddit) Mining Verus is impossible on any Raspberry device. The Raspberry company did not license all CPU instructions, so the required functions are not available on Raspberry branded devices. As far as I know Raspberry is the only brand that crippled the CPU, so any other ARM device should work." I picked up your recent interest in coding for ARM processors after reading the CryptoMining-Blog post on VerusCoin (VRSC) mining. I have been able to compile XMrig and tpruvot's CPUminer-Multi on my R-pi. The above CCminer packages (Monkins & Oink70) will not compile. I am currently mining VerusCoin on a new Orange Pi 5. Verushash and MinotaurX look like good targets for coding, if you are able to find the right functions. Raspberry Pi 5 is scheduled to hit the market this month, I believe. The CPU runs at 2.4 GHZ. Hope to see some fresh code to match! --scryptr Hold off on testing, it won't compile. I have now have a Raspberry Pi so I have to work throuh the build issues. More news soon.

I just got my Pi 4B yesterday and started compiling today. A lot of work to do remove all the SSE2 hooks in the code, Pi can do (almost) anything SSE2 can and some things SSE2 can't. I just have to figure out what those things are. I've found 2 very interestings so far: ARm as a REV instruction cna can reverse bits in a vecto or word, or word in a vector. X86_64 can't do that except maybe with AVX512VBMI2. ARM has no shuffle instruction, A RISC issue because random shuffles need code, either SW or microcode. ARM shuffles have to be coded in SW using integers while x86_64 is a CISC architecture with microcode. As far as AES and SHA are concerned, the code is already well segregated so Pi can live with out it just like Core2 can. I'll ignore that code and focus on other parts until I get a CPU with the features, or someone in the community with one volunteers. It's not really about Pi though, the Pi is just a test vehicle. ARM is moving up, they'e in laptops and Macs, soon we may see ARM desktops. I want to see how they might perform with AES and SHA2 against Intel and AMD core vs core.

Development is progressing well in spite of a few problems, The next release will be soon and most algos will be supported with only a couple of exceptions. Many SSE2 optimizations were easily translated directly to NEON and some NEON development is also applicable to SSE2 which helps older x86_64 CPUs that don't have AVX2. It's a win-win for both architectures. Go to the github wiki for the technical details and stay tuned.

Correct. The CLI is limited to 64 bit integers. The 64 bit mask is repeated for CPUs 64 to 127, 128 to 191, etc. On windows the mask used is the size of a CPU group (CPU groups not supported with prebuilt binaries) and is repeated accordingly for each group if the group size is less than 64. I can't think of a practical case where affinity would not be repeating pattern and require all unique bits. If you have a CPU with more than 64 threads I would be interested in your experience.

I answered twice, I don't what else to say. Title: Re: [ANN] cpuminer-opt v23.15, *NEW* ARM support, optimized multi-algo CPU miner Post by: Lirei54 on February 24, 2024, 02:31:28 PM Hello JayDDee.
Tell me how to specify the value for yespower_params.perslen = strlen(opt_param_key) in the miner; What if perslen value is not zero? and, for example, equals 80 When specifying only three parameters, .N . r. pers there is always a rejection of the solution in the miner When mining with the yespower algorithm.

The perslen is derived from the length of the param-key arg. If the coin spec has the length wrong (at least one instance I know of) if effectively changes the pers string (param-key). Check out the yespower section here... https://github.com/JayDDee/cpuminer-opt/wiki/Supported--Algorithms If you still have problems post full problem description including command line and miner output.

It's a difficulty targetting error. This is either a miner bug or a pool bug. Since yespower has been working for years a pool bug is likely. If you let the miner run for a while you should see some accepted shares. You can also use -m as a workaround to increase the target diff and filter out the lower diff shares that would be rejected.

The Raspberry company did not license all CPU instructions, so the required functions are not available on Raspberry branded devices. As far as I know Raspberry is the only brand that crippled the CPU, so any other ARM device should work." I picked up your recent interest in coding for ARM processors after reading the CryptoMining-Blog post on VerusCoin (VRSC) mining. I have been able to compile XMrig and tpruvot's CPUminer-Multi on my R-pi. The above CCminer packages (Monkins & Oink70) will not compile. I am currently mining VerusCoin on a new Orange Pi 5. Verushash and MinotaurX look like good targets for coding, if you are able to find the right functions. Raspberry Pi 5 is scheduled to hit the market this month, I believe. The CPU runs at 2.4 GHZ. Hope to see some fresh code to match! --scryptr Hold off on testing, it won't compile. I have now have a Raspberry Pi so I have to work through the build issues. More news soon. Looking for miners with ARM CPUs. cpuminer-opt-3.23.4, source code only, has initial support for 64 bit AArch64 CPUs with NEON, SHA2 & AES. It's experimental and untested. It needs testers. See Wiki for details... https://github.com/JayDDee/cpuminer-opt/wiki/Support-for-AARCH64 ANSWERING MY OWN POST ================= The Rpi 5 supposedly has the crypto instructions. See below: (QUOTE from Reddit) "@hyc Amazing that they finally quit being cheapskates and decided to pay for the crypto instruction extension that every other ARM producer in the world has included for the past 8 years already. I wonder what changed their minds. So it’s another Broadcom chip quadcore with only 2MB L3 cache. I.e., only enough cache to run a single RandomX thread. The other cores will be wasted. These have always been and continue to be worthless junk. For practical use these days you need closer to 4GB RAM per core, and of course 2MB cache per core. This thing only has enough resources to utilize 1 (core." (END QUOTE) Although I have been able to compile Xmrig on my Rpi 4, none of your recent crypto builds worked. I finally was able to purchase an Rpi 5 from Adafruit and will try again. I have several Orange Pi 5 boards mining Verus coin. I'll be able to check the Rpi 5 hashrate in comparison. Apologies to the quoted Reddit user. The post is 5 months old, and from a MoneroMiniing thread. I have not done a thorough search to verify its validity. --scryptr Title: Re: [ANN] cpuminer-opt v3.23.3, open source optimized multi-algo x86_64 CPU miner Post by: JayDDee on March 02, 2024, 01:34:03 AM ANSWERING MY OWN POST ================= The Rpi 5 supposedly has the crypto instructions.

It's nice to know RPi5 has crypto. I've done testing on RPi4B, definitely no crypto, OPi5 with crypto, and Apple M2 from a VM. I can't get it to compile on native MacOS. Crypto doesn't work in the VM but that could be a VM issue. I would be surprised if M2 didn't support crypto.

I think I missed this point. The Windows builds won't work on RPI or OPi, they're for X86_64 not Arm. If you have problems compiling on RPi (or OPi) with Linux it's probably missing packages. It may depend on how you install Linux. If you installed from an custom image file it may not have all necessary packages. I installed using using normal installation procedure for Ubuntu using the Arm server ISO and had no issues compiling afterward. |
