Title: [XMG] M7M CPU mining discussion thread Post by: joelao95 on November 16, 2014, 07:57:19 PM This thread is to collect hash rates of CPU mining on the M7M algorithm (XMG, OP: https://bitcointalk.org/index.php?topic=735170.0 (https://bitcointalk.org/index.php?topic=735170.0)). This will facilitate us to make a wiki page.
Please post your CPU, hashrate, the miner (which compilation or compiled from source code), and any other means of improving performance you want to share. M7M miners: http://coinmagi.org/files/magi-minerd/Magi-miner-v0.1.zip This includes Spexx and MarcusDe's compilations (generic). Spexx's software package is way of better. Spexx's latest package: https://bitcointalk.org/index.php?topic=735170.msg9503440#msg9503440 MarcusDe full list: http://graymines.net/miners/magi/v2/ For linux, compile from source code: https://github.com/noncepool/m7magi-cpuminer-v2 Estimate hash rate in kh/s (according to Spexx's research) Locate your CPU in https://www.cpubenchmark.net/cpu_list.php (https://www.cpubenchmark.net/cpu_list.php); divide "Passmark CPU Mark figure" by 1000 and then multiply by 3.6.

I've noticed better hashing with looser timings for instance. So if you find it's sitting there and twiddling, maybe give it some slack.

Yeas I admit that overclocking is significant, but for 1Hz haswell is doing more work than any AMD CPU. Yeah, but I got more of them! They're just different chips. AMD out-performs Intel in some (http://i633.photobucket.com/albums/uu53/acatphoto/Tech/Benchmarks/Clip0003.jpg) things, not in others (http://i633.photobucket.com/albums/uu53/acatphoto/Tech/Benchmarks/Clip0002.jpg). Just now found out that the trick of running 7 individual threads bound to individual cores doesn't work with my 8350. At 5 threads they all slow down a wee bit, and at 7 threads there's no real difference. The most important thing though is that price difference. Consider, I got chip and board for $400! You can't even get a motherboard over $300 for AMD, top stuff for Intel is $500+. There are a hell of a lot of people out there who probably wouldn't even have a system if it weren't for AMD's el-cheapo combos. Essentially though, they're just different.

Linux. The miner was built from https://github.com/noncepool/m7m-cpuminer-v2.git Passmark is 5422 so the estimate would be 19.5 khash/s, presumably on all 6 cores. I have it set for 8 threads and it is taking most of 4 of the cores (~365% CPU). Sorry, I have a couple threads devoted to other coins, too, plus some wallets. Still, I am seeing 16.5 khash/s. That is giving me about 4.4khash/s/core or 2.2khash/s/thread I'm happy. I'll never be rich, but I am having a lot of fun. Title: Re: [XMG] M7M CPU mining discussion thread Post by: SpeedDemon13 on November 18, 2014, 05:22:56 AM I know I posted this on the XMG thread, but has anyone done a comparison of hash/wattage of cpus? What is the most ideal cost/performance cpu for mining M7M algo?
Title: Re: [XMG] M7M CPU mining discussion thread Post by: Atomicat on November 18, 2014, 11:57:42 PM Continuing a discussion on the main thread....
Spexx! Just wanted to possibly confirm a bit of bad news for us AMD miners. It seems that when limiting single threads to single cores, we still get a drop in speed. Basically, once you go past five instances you get that drop no matter what. 7kh/s per thread up to 5 or so, then slowly drops to 5 and a bit per. Just thought I'd mention before I start digging for ways and means. Would this be on a machine with 8 cores? You are probably seeing a near linear increase in total hashrate as you add single-threaded minerd instances up to 5 in number, then see a drop-off in the per-thread hashrate as you add further instances. The reason for this is that the processor load from each instance is spread across 3 cores in any event (given at least 3 cores to run on). If you run up a single instance of minerd.exe with a single thread on a multi-core machine that is otherwise idle, this can be seen using Task Manager. Once you have 5 instances on an 8 core machine, you will start to get overlap - there is no core that will be 100 percent free for a sixth, seventh or eighth instance and the instances start to compete with each other for CPU time. While this will cause a drop in the per-thread hashrate as you have observed, the total hashrate obtained is optimal when you have the number of instances/threads equal to the number of processors in the machine and the CPU utilization will be maxed-out 100 percent at this point. Deliberately restricting an instance of minerd.exe to a single core on a multi-core machine is not the best way to do it. It is very inefficient. Each instance of minerd.exe should be allocated a subset of 3 processors to run on for best performance. This applies to Intel processors as much as it does to AMD processors from what I have observed. This is why I wrote a shed load of code to handle it ;) I see... that's somewhat counter-intuitive but maybe because of old-school thinking. I would have figured the increase came from having task run on "it's own core" so what I was doing was starting different instances with the /affinity command, which I saw you were using in your batch files. So you're setting them to spread over three cores? As in 123,234,345,456,567,678 etc? Guess I'll try that and see what I get. Y'know... I think I'd gain more by moving my rig to where it can get some sub-zero air. Then of course there's more problems. Last winter I found out they don't put antifreeze in closed-loop systems. There is such a thing as being too chill. Title: Re: [XMG] M7M CPU mining discussion thread Post by: Spexx on November 21, 2014, 01:17:17 AM So you're setting them to spread over three cores? As in 123,234,345,456,567,678 etc? ... then 781, 812 to finish-off. Yes that is precisely what the automine.bat program does. There is a refinement in as much as when the number of cores is a multiple of 4 it will wrap around itself to saturate a group of four cores. E.g on an eight-core machine it would go:- 123, 234, 341, 412 then 567, 678, 785, 856 The only reason that I wrote it in such a way was for mathematical convenience when dealing with hex affinity masks. If you start crunching the numbers yourself you will see what I mean ;) The net result is exactly the same as going 123,234,345,456,567,678,781,812 since each core is used three times in either regime. It is certainly possible to start multiple instances of minerd without specifying a processor affinity mask at all, thus letting Windows make all those decisions for you at runtime, but it tends to make a pig's ear of it. You end up with a chaotic mess which fails to fully utilize the CPU and generates inconsistent hashrates. Everything seems to run smoother when you take control and do a proper job on it. Title: Re: [XMG] M7M CPU mining discussion thread Post by: JimmyTaylor on November 21, 2014, 01:24:30 AM I think this looks to be the best way to organize convos about that specifically.

Interesting, however... Might not be an issue with AMD's bulldozer and might have more to do with hyperthreading. Dig. Here's a run, 7 threads given time to settle in. Shows that drop of course down from 6.9. http://i633.photobucket.com/albums/uu53/acatphoto/Tech/Scraps/Magi7thread.gif This however, is a run, single threads, affinity set to e0, 70, 38, 1c, 0e, 07, 83. It looks like it's going to average out to about the same, possibly less, and there's a lot of work restarts, no doubt from all those single threads jammed at the doorway so to speak. http://i633.photobucket.com/albums/uu53/acatphoto/Tech/Scraps/Magi1threadspread.gif This is the first AMD chip I've used since this 1800+ I had quite a while ago. An upgrade from a quad-core socket 775 chip/board that went to better pastures (bro's accounting and email). This scene has re-sparked my curiosity bug for programming, the low-level kind. Previously I would have probably got into programming PovRay, now that I've got something faster than a 486 to render on, but now I wanna know what's in those cores, and what the hell all these new instruction sets are about (including the gpu ones). First project... something that will adjust core voltages and frequencies on the fly, dependent on core temperature. Why? Because the manufacturer's overclocking software sucks so much ass. :D This will be fun, I haven't done asm since I had a 386!

I just started up my bulldozer with 12 threads to see what happens. Collision city, and less hash than with 7 cores. Just give it five, best for efficiency. There is that drop-off that Spexx and I were discussing, you might try single threads and setting processor affinity as he described. Yeah it is fun! I'm fairly competitive, love to learn, and love to overclock to the moon. Title: Re: [XMG] M7M CPU mining discussion thread Post by: ulfie on November 22, 2014, 02:40:23 AM Thanks, mate. That gave me an extra 6% on the overall hash rate.
Title: Re: [XMG] M7M CPU mining discussion thread Post by: Atomicat on November 22, 2014, 07:59:02 AM So I downloaded some ASM materials, reference manuals for op-codes, registers, data types, addressing modes and such, and this is what I find...

Mommy... I'm scared! Can we go home now? Calm blue ocean calm blue ocean calm blue ocean. Y'know, the 6502 was such a nice chip, such a nice chip, why did it have to grow up and get all mean? 6502...

One thing I was good at back when was optimizing machine code, back when we actually had to write our own .h libraries for things like drawing lines with those fancy COLOR videocards! Last of that I did was on a 386 though, then it was off to Acad Lisp and other more profitable things.

Hard fork [client version v1.2.0.1] Please update the wallet to v1.2.0.1 (mandatory): Windows: http://coinmagi.org/files/magi-release/win32_magi_v1.2.0.1.zip (http://coinmagi.org/files/magi-release/win32_magi_v1.2.0.1.zip) Linux: http://coinmagi.org/files/magi-release/linux_amd64_magi-qt_v1.2.0.1 (http://coinmagi.org/files/magi-release/linux_amd64_magi-qt_v1.2.0.1) Source code: https://github.com/magi-project/magi/ (https://github.com/magi-project/magi/) This update includes the following hard forks: PoS hard fork at block 131100 for better staking results (Expected on January 6) PoS-II Protocol V2 hard fork at block 131300 (Expected on January 6) PoW-V2 hard fork: 1/7/2015, 12:00:00 PM EST time (GMT-5:00) Details regarding this update: https://bitcointalk.org/index.php?topic=735170.msg9991269#msg9991269 I did spend some time and tried to figure out the CPU algo, but all have been done just under the range of my knowledge. People are talent; no one would know the capability other people can do. It's not my intention to hold firmly the CPU algo statement. PTS was arguing only CPU minable, and was awarding how many dollars for a GPU miner? Everyone knows that PTS is minable with GPU now. Once upon a time, someone was suggesting me that, go for a CPU algo, finish the PoW mining and then going into PoS. That was right likely, but not all to me. Pure PoS is not right way I figured. Wolf0, you're absolutely right (not the GPU part since not proved yet), that "just because no one bothers to spend the time on it" cause it's unprofitable. Let me extend the statement, the idea of GPU mining is neither profitable for now, nor profitable in the future even when magi gets into top. I encourage people to work on a GPU miner for magi, but surely up to you whenever you see a time coming with profits. Wondering?... read the OP, or the coinssource article, evok3d did spend a lot time researching and writing before publishing the article: http://www.coinssource.com/coin-magi-a-cpu-miners-dream-proof-of-mining-pos-ii/ I've spent time on this, and the idea behind it worth of a try; I want to say magi is a coin CPU minable "ever". I almost forgot to post the miner, for some people who may want to run it in computers with limitations, just use the "-e" option. # m-cpuminer-legacy https://github.com/magi-project/m-cpuminer-legacy Code: minerdlegacy -o stratum+tcp://pool_url:pool_port -u pool_user.worker -p password -t thread_numbers -e cpu_efficiency This is none different from the regular miner, except that an option "-e cpu_efficiency" is added, where cpu_efficiency is a number between 1 - 100, for example, 50 representing for 50% of CPU usage. A few instances: -e 75 --> http://www.coinmagi.org/misc/images/magi-thread/OP/2014-12-29/cpu-75.png -e 50 --> http://www.coinmagi.org/misc/images/magi-thread/OP/2014-12-29/cpu-50.png -e 25 --> http://www.coinmagi.org/misc/images/magi-thread/OP/2014-12-29/cpu-25.png -e 1 --> http://www.coinmagi.org/misc/images/magi-thread/OP/2014-12-29/cpu-1.png Title: Re: [XMG] M7M CPU mining discussion thread Post by: Prelude on January 02, 2015, 06:24:41 AM Hi guys,
Which miner is best for an AVX CPU and AVX 2 cpu? Thanks. Title: Re: [XMG] M7M CPU mining discussion thread Post by: Spexx on January 02, 2015, 05:53:34 PM Hi guys, Which miner is best for an AVX CPU and AVX 2 cpu? Thanks. If you are compiling the miner for Linux, the compiler will create avx and/or avx2 compatible code if you include the string -march=native in the CFLAGS. If your operating system is 64 bit Windows, then to support avx and avx2 instruction sets you need Windows version 7 SP1 minimum. My miner software package for Windows includes four versions of the miner: 32 bit, generic, avx and avx2. The software selects the correct miner for you automatically. https://bitcointalk.org/index.php?topic=735170.msg9412187#msg9412187 (https://bitcointalk.org/index.php?topic=735170.msg9412187#msg9412187) Generally speaking, the avx version is about 1 percent faster than the generic version, while the avx2 version is almost 4 percent faster. Happy hashing :D Title: Re: [XMG] M7M CPU mining discussion thread Post by: Prelude on January 02, 2015, 08:12:00 PM Hi guys, Which miner is best for an AVX CPU and AVX 2 cpu? Thanks.

Title: Re: [XMG] M7M CPU mining discussion thread Post by: PeaMine on January 05, 2015, 12:46:12 AM Anybody actually making a profit in cpu mining? If so, please impart your wisdom and coin choice upon me ::) Due to free electricity/botnets I don't think this has existed for some time. I've searched a lot and about the best I've found came to around 30% less than I needed to break even with 0.14 kwh electricity.They are changing how hash rate affects payout for M7M it seems however, so maybe it will be one of the first to fix this. Title: Re: [XMG] M7M CPU mining discussion thread Post by: joelao95 on January 06, 2015, 04:40:07 AM Wolf, you're welcome to do so; also I'll welcome GPU if anybody could do. Well, I don't want to freak out all CPU miners because of this possibility or possible existing GPU miners already.
People mining XMG should take a look at it's block reward design. Don't mine too hard, or PoW blocks will stop yielding coins (block chain still going). Different people have different understanding though, check out the paper (need update upon the coming hardfork, but the same concept applies). http://arxiv.org/abs/1409.7948 The reward is designed best at the CPU mining level. Anyone fire up CPU farm or GPU may push reward towards a trivial level. The coming hard fork will tailor the reward at a much accurate level. Remember, the more CPU miners (not too high hashrate though), the more secure of the reward. The more GPU miners (let's say in the future and assuming they have significantly high hashrate), no actual rewards will be yielded. Please remember to update your wallet above v1.2.0: Details: https://bitcointalk.org/index.php?topic=735170.msg9991269#msg9991269 p.s., I am actually keen to see how magi's block reward design could cut down ASIC miners in a scrypt coin.

Samsung Exynos5422 Cortex™-A15 1.8Ghz quad core and Cortex™-A7 quad core CPUs ~10kH/s :o Not bad for 10 Watt. ;D edit: I must correct myself, it does "only" 7.66kH/s. The 4 big cores showed the hashrate (1.28kH/s each) way quicker than the 4 little cores (0.63kH/s each). Still quite impressive I think. :D Title: Re: [XMG] M7M CPU mining discussion thread Post by: jawitech on January 19, 2015, 07:30:05 PM The long-term goal of Magi is to achieve, that the majority of miners are simple home computers, Raspi's or similar ones like the one in your link.

Screenshot (NSFW): https://ottrbutt.com/miner/xmgwolf-01192015.png Not bad. What is the usual hashrate for this CPU? Did you start selling your optimized miner or will you keep it privately? Title: Re: [XMG] M7M CPU mining discussion thread Post by: jawitech on January 20, 2015, 03:55:45 AM Haven't sold it; I'm not sure what I'll do. Normal hashrate is about 40kh/s at the same clocks. If you like the concept of Magi and would like to make more profit, I'd appreciate if you don't sell it to miners with big hashrate. Doubling low miners like my 5-8 kh/s wouldn't be a problem for Magi ;D As you usually want to make profit, I hope you support our way and make your profit with mining.

My other plan was releasing it for a bounty, if one showed up. We would think about a bounty if you don't :P No, honestly, the whole team is happy that you're interested in and mining Magi. But according to the plans that you know, it would be awesome if you would not help (at least big miners/farms/GPU miners) to increase their hashrate considerably. The goal is and will remain to give advantage the usual miner with low hashrate and discourage big miners for a fair distribution.

The m7magi-cpuminer-v2 is an old one now (still works, but much slower) and the latest source is at https://github.com/magi-project/wolf-m7m-cpuminer-V2 (https://github.com/magi-project/wolf-m7m-cpuminer-V2) which I assume is the one you are having problems with. I remember having a few problems myself, compiling it for Windows. I seem to remember solving it by copying files from the m7 sub-folder to the root folder - all the files starting with sph_ and ending with .h, but I am not sure that this actually was the fix now - memory fades. Title: Re: [XMG] M7M CPU mining discussion thread Post by: Atomicat on April 11, 2015, 10:41:14 AM hi im planning to mine magi using a 4670k. will it gain decent profits? or i should just buy at the exchange? What hashrate do you have with this ? a 4790 mines 30 kh so im guessing a little lower than that With my i5-3570k I got 60 KH/s and 6XMG/day so with 30 KH/s he should have 3 XMG/day. shouldnt i get much higher than you? 4670k > 3570k right? did you oc your procy? Yep, he's better. But I haven't oc my CPU so I don't understand where does the error com from. 4790? This 4790? https://cpubenchmark.net/cpu.php?cpu=Intel+Core+i7-4790K+%40+4.00GHz&id=2275 Yes, you should definitely be getting way more. I can match that score with my bulldozer, but never denied that it takes a hefty overclock to do so. At stock 4.0 Ghz I get 15 Kh/s per thread.

Ouch! Sounds like the current cooler is a bit off or needs a refresh on the thermal paste. In any case, cooling is good, more cooling, better, can't have enough! But enough about liquid nitrogen, reality! That Corsair H55 is about the cheapest you can get, and was the first liquid unit I ever got. Now doing a good job cooling my 7950. (http://i633.photobucket.com/albums/uu53/acatphoto/Tech/BadGirl03.jpg) It is however, about the cheapest unit you can get. Entry level on liquid is still about $60-$70, but it's worth it! I've never looked back and wouldn't use anything but. The performance on even the low-end units like that Corsair is superior to anything but the best (and most very expensive) air units. You will be spending about $50 anyways on a superior air unit. Other advantages... that Corsair unit replaced a Coolermaster V10. You know how big those things are? This big... http://article.techlabs.by/img/article/8934/IMG_5583.jpg Ye-gads! Aiee! And the Corsair unit outperformed it. Never looked back. Here's a few minor factoids for you to help you choose your new toy (and you are gonna get one, right?) Your rads are measured by width, so a "240" will be 240mmX120mm, a 280 is 280mmX140MM, and so on. Heat dissipation is mostly by area so if you can get a cheap 240, gravy. Think of it as basically boosting your cpu, because you'll get a lot more performance out of it. I'm SO glad to have my water unit back in action because now instead of worrying if I"m pushing it, I'm happily cranking away at 5.0 Ghz. 20% more machine!

But the design discourages the hash rate from going up as the value of the coin increases, which is exactly the source of security in bitcoin -- one might suspect that this would just as likely cap the value of the coin as anything else. At least it helps answer the question of whether it's worth implementing it on a GPU. ;) But next month will be funny for Magi when the first Skylake CPUs come out with Intel's SHA extensions.

It's really not profitable at all right now, so if you like the coin, it's much better to just get it off the market for much cheaper :) I think the competition consists mainly of IT workers that have massive server farms where they can run this on for nothing, but a personal guy wouldn't really be able to compete against this, unless you're happy with hurting your CPU 24/7 for next to nothing ;) Title: Re: [XMG] M7M CPU mining discussion thread Post by: Lionel on July 23, 2017, 01:50:52 PM That sounds about right.

But i wonder how the infected PC users do not even notice that their CPU and fan are working at full speed ... hence i don't believe that botnets are used for this task Title: Re: [XMG] M7M CPU mining discussion thread Post by: akuci on July 23, 2017, 02:22:41 PM Just keep on mining, and hope the price will raise. :)

Btw with lots currencies it is: You have money? You can make more money! For mining Magi you dont need money to mine some. Just a simple cpu can do it. Title: Re: [XMG] M7M CPU mining discussion thread Post by: akuci on July 24, 2017, 03:12:31 PM I mine it with all of my rigs, with G3930 Celerons.
No hash decrease on EWBFs miner, runs almost for a month like that without a problem. I don't know if it's the miner, or the OS, but the OS, or any other app have always higher priority than the miner. So your XMG hash will decrease if the OS needs some CPU power, and then when it's done, it will give all the CPU to the miner again. You can really mine some XMG on your regular desktop too, not just on a mining rig.

Still end up for some good numbers at the end of the day. Granted, I'm one of those "IT Guys" that have a lot of miners, but still profitable for 2-3 miners. |
