Title: [ANN][MTC] GPU Miner for Metiscoin - 35% FASTER on R9 280x Post by: girino on February 03, 2014, 08:15:01 PM I Just released a GPU (openCL) miner for MTC. If anyone cares to test. Performance is not great though. I did it just so we have something to do with our GPUs while iddle.
Source code is available at: https://github.com/girino/xptMiner and Binaries (for windows only at present, will add linux later tonight) https://www.dropbox.com/sh/2wv2awwgebpdo0m/STzOU5tlXa Please let me know if it works for you and how fast (or slow) it is on your GPUs. Edit: Linux, Windows and OSX binaries available. Same download location! Edit: Build 5 fixes the reconnect bug and the speed reporting bug. Edit: Build 7 incorporates gigawatt's speed improvements. developper fee is up to 3% by default so i can give gigawatt a share for his work. As always, binaries for linux, windows and osx are available on the links above. Edit: The networking code from ypool's latest xptminer was merged back into Build 8. Several changes and tests were made to ensure stability (no more "0kh/s" after some hours, no more closing on network disconnect or server down). Faster than ever, and two new hidden options: -s to set the step size (in powers of 2, defaults to 2^20), and -a to set variations on algorithm. Currently supports "-a 1" for lookup tables in constant memory and "-a 2" (default) for tables in global memory. -a 2 is faster in most systems. The code for metis was reverted to a previous version since it is 2x slower on some NVidia GPUs. Binaries and code available, as always, on the links above. Edit: Build 9 uses local memory more intensely and gets up to 35% speed improvements in GPUS with lots of local memory. For those with small local memory, the "-a 2" hidden option reverts to the old version of the opencl (Older cards or Amazon EC2 need this option). Also, ypool instability helped figure out more networking bugs, so networking is even more stable! More stable, UPGRADE TO AVOID LOST CONNECTIONS WHEN YPOOL DOWN!

Title: Re: [ANN][MTC] GPU Miner for Metiscoin Post by: braytz on February 03, 2014, 09:47:39 PM it's working now (but with less kh/s...before it was 5300 kh/s with amd 6970,now it's 4700).
good job ;).

I had to do a quick fix to make it work. I'll look into the bug with more detail later today and see how to make it faster again.

- Fixed the 0x8000 worksize limitation (workaround for invalid shares reported earlier). - Linux and OSX binaries now available.

Title: Re: [ANN][MTC] GPU Miner for Metiscoin - Linux, Windows and OSX binaries! Post by: Tons0fun on February 04, 2014, 11:01:17 PM Any idea why the miner seems to just stop finding shares after a while? I noticed the kh/s going down over time but it was still finding shares pretty quickly, but this morning it was reporting 0 kh/s and not finding shares. Win 7, R9 290 if that helps.

Title: Re: [ANN][MTC] GPU Miner for Metiscoin - Linux, Windows and OSX binaries! Post by: Tons0fun on February 04, 2014, 11:56:58 PM It seems to be all over the place but I saw as high as 29000kh/s but consistently around 15900kh/s till it starts going down. Granted, that is for two 290s.

Win 7, R9 290 if that helps. never heard of it stopping finding shares. isn't it a network problem or something? maybe the pool was down. about the speed, the original xptminer from ypool used a 32 bit counter for hashes, but it overflows quite quickly with gpu hashing speed (30 minutes to 1 hour, depending on the gpu). so reported speeds after the first half an hour or so are just bogus. I'll release a fix for that later today. (code is already fixed, but i didn't create the binaries yet). Title: Re: [ANN][MTC] GPU Miner for Metiscoin - Linux, Windows and OSX binaries!

The decreasing hash rate is not to worry about, itīs simply a 32bit counter wrapping (reaching itīs maximum value and starts over from 0) it is only visual and wonīt affect actual performance. Well now that I actually helped someone for a change I would like to give some feedback to the developer. Currently if/when the miner lose connection with the pool there are never any attempts to connect back again, it would be awesome to have a reconnect feature so we donīt lose any hash time. I know I'm a lazy bastard asking you to implement this rather than doing it myself but it is probably a quick matter for someone familiar with the code :) Also, thanks a lot for your efforts with this miner.

This is quite strange since i didn't mess with the networking code from ypool, but you're not the first to point it out. I'll look into this today (the 32 bit counter is already fixed in the code and in the linux and mac binaries, just the windows binaries still have the bug). Thanks for the support. Title: Re: [ANN][MTC] GPU Miner for Metiscoin - Linux, Windows and OSX binaries! Post by: girino on February 05, 2014, 01:58:11 PM NEW RELEASE
Build 5, fixes the following bugs: - bogus hash count after half on hour or so in fast GPUs. Now it report the right hashrate for several years. - Not reconnecting after disconnection. Now it waits 45 secs after every disconnect and tries again. New Features: - counts invalid and valid shares separately, so it is easier to spot problems. Todo: - several AMD optimizations are on the pipeline, but they were not yet mature (too many invalid shares) so they were NOT included in this version. Download binaries and source from the same old place. OSX binaries not ready yet, only linux and Windows available. Binaries link: https://www.dropbox.com/sh/2wv2awwgebpdo0m/STzOU5tlXa Source code: https://github.com/girino/xptMiner Thanks, and enjoy the new version.

I noticed that you can include the CPU in the list of devices to be used with your miner, is this efficient? Not at all. It will use opencl on the CPU, and you will get at most half the hash rate you get with a decent CPU miner. Title: Re: [ANN][MTC] GPU Miner for Metiscoin - Fixed bugs!

Hi all, I just released a new build of this miner with several improvements, thanks to gigawatt. My current version is slightly faster than his, but this might depend on the machine you're running it. (Mostly because i copy AES tables from __constant memory space and he copies it from __global). The binaries for windows, osx and linux are still available on the same old place: https://www.dropbox.com/sh/2wv2awwgebpdo0m/STzOU5tlXa Please run and enjoy.

Well, the difference between this version and gigawatt's version is how we manage the lookup tables. Depending on how your card organizes its memory, his version will be faster.

The only difference, as I said, is that I use constant memory instead of global for the lookup tables.

Post by: girino on February 27, 2014, 11:01:34 PM NEW VERSION RELEASED - Build 8
This time my focus was on networking, stability and 32 bits. The networking code from ypool's latest xptminer was merged back. Several changes and tests were made to ensure stability (no more "0kh/s" after some hours, no more closing on network disconnect or server down). Faster than ever, and two new hidden options: -s to set the step size (in powers of 2, defaults to 2^20), and -a to set variations on algorithm. Currently supports "-a 1" for lookup tables in constant memory and "-a 2" (default) for tables in global memory. -a 2 is faster in most systems. The code for metis was reverted to a previous version since it is 2x slower on some NVidia GPUs. Binaries and code available, as always, on the links above. Source code is available at: https://github.com/girino/xptMiner and Binaries (for windows only at present, will add linux later tonight) https://www.dropbox.com/sh/2wv2awwgebpdo0m/STzOU5tlXa Enjoy. Title: Re: [ANN][MTC] GPU Miner for Metiscoin - STABLE, works on 32 and 64 bits. Post by: Replex on February 28, 2014, 04:33:43 PM How do I set the step size( -s)?
How high can I go etc? Also, great work! My GTX 660ti went from 21000 k/hash to 24000 k/hash so far! With -a 2 it ran at about 20000 k/hash. With -a 1 it went 4000 k/hash higher! Want to tweak the step size to see if I alter it even more! Title: Re: [ANN][MTC] GPU Miner for Metiscoin - STABLE, works on 32 and 64 bits.

(they are powers of 2, so 15 means that each step processes 2^15 hashes = 32K. The default is 19, which means 512K hashes in each step. I think your card would go best with -s 22 or higher). Title: Re: [ANN][MTC] GPU Miner for Metiscoin - 35% FASTER on R9 280x Post by: girino on March 02, 2014, 02:41:04 AM NEW RELEASE, 35% faster on R9 280x, SOLVED LOST CONNECTION PROBLEM WHEN YPOOL DOWN!!! Build 9 tries to maximize use of local memory. Really fast on GPUs with fast local memory and lots of it (newer AMD cards). If this version is slower in your GPU (NVidia or older cards), use option "-a 2" on the command line to revert to the old OpenCL code. Also, no more freezing on connection lost. (useful on those times of ypool instability). Techinacl details bellow. EVERYBODY SHOULD UPGRADE TO AVOID FREEZING!!! Very imoprtant now that ypool is being constantly DDoSed... For those more into the techincal issues, the changes are: 1- use of local memory instead of global memory to pass hashes between the several hashing functions (keccak -> shavite -> fugue). This improves performance on machines where local memory is at least 64 * work_group_size + 8K. 2- Linux (and cygwin, for the matter) do not set an error on socket disconnect when calling recv. It just returns a 0 size. Since the original (windows code) was expecting that an error is sent on those cases, the linux code just kept trying forever to receive data in a closed connection. So now, when checking for errors, it is also checking if return size is 0 to mark connection as lost. This solves the "freezing disconnect" bug that was haunting all of us. Links for download are the same as always, source code is available at: https://github.com/girino/xptMiner and Binaries (linux 32 and 64 bits, windows 64 bits and OSX): https://www.dropbox.com/sh/2wv2awwgebpdo0m/STzOU5tlXa Enjoy!

Title: Re: [ANN][MTC] GPU Miner for Metiscoin - 35% FASTER on R9 280x Post by: girino on March 06, 2014, 02:51:12 AM NEW POOL -- BETA TESTERS WANTED
For the eager ones: http://pool.girino.org/ Miners can be downloaded here: http://girino.org/metisminer/ Hi all, As you know, whenever ypool is down (and it happened a lot last week) we are left without any way to mine (and the network stops confirming transactions, since no mining is done). So, to address this problem i developed this new pool, based on pushpool and MPOS, and i am trying to test it. But alone, it's like solo mining: completely useless. So please, pretty please, tho who can spare some of your time and miners, please mine in this new pool. It uses a different protocol from ypool (getwork, while ypool uses x-pushtrough, that AFAIK is only used by them and was probably developed by them). So you will need to download a new miner. IT IS STILL EXPERIMENTAL, I NEED BETA TESTERS SO WE CAN BREAK OUR FIRST BLOCK AND SEE IF EVERYTHING WORKS! Please report any problems you find, send me any advice you have about running a pool, and anything you want, either at pool@girino.org or by PM here. If everything works great, I'll be launching it officially and asking the dev to include it in the coin's page... Thanks to all! And please, test, test and retest! We need to make it work!

Title: Re: [ANN][MTC] GPU Miner for Metiscoin - 35% FASTER on R9 280x Post by: girino on March 06, 2014, 07:14:37 PM ALL BETA TESTERS UPDATE THE MINER PLEASE!!!
download the newer versions at the same place: http://girino.org/metisminer/ Sorry to all, the old miner had a bug that prevented it from finding new blocks. Technical explanations bellow. Those who participated in the beta test up to now will share the bonus 50 MTS i had promised. See bellow for the shares each one will get. I'll contact you in order to send you the MTS. Now, the technical stuff: When writing the miner I got confused as to how the data was sent on the getwork protocol. I was auditing the shares submited to see why it took so long to find a block and found out that good hashes were being rejected by the metiscoind wallet. I found out that hashes where sent in "little endian" 32 bit encoding, while i was using "big endian" encoding. So a swap of the bytes was needed. I now fixed it and have tested if the hashes generated by the walled are compatible with the hashes generated by the miner (lots of debugging in the wallet to do this). So, I thank you ll that participated in the beta up to now and urge you to update the miners so that we can start breaking lots of blocks! PLEASE DO NOT LEAVE THE BETA TESTING, we still need to test lots of things in the miner and pool server. The 50 MTS for the early testers will be split acording to the following table:
Thanks to all, and again, PLEASE UPDATE THE MINER AND DO NOT LEAVE THE BETA TESTS! Title: Re: [ANN][MTC] GPU Miner for Metiscoin - 35% FASTER on R9 280x Post by: breakbeater on March 06, 2014, 07:30:56 PM I can't download the new miner:

For those of you who asked about the CPU miner, good news: The new version of the miner supports both GPU and CPU mining. As i'm not sure if the GPU version runs without a GPU driver installed, i produced 2 versions of the miner: minerd.exe which supports both CPU and GPU, and minerd-cpuonly.exe, which as its name says, supports only CPU mining. as always, downloads are here: http://girino.org/metisminer There are no news in the GPU miner, so you only need to update if you intend to do CPU mining.

There is also a .bat file as an example of usage. On linux you must download each version separately. The metis-minerd-linuxXX-build4.tgz is the GPU version, and the metis-minerd-CPUonly-linuxXX-build4.tgz is the cpu version. If your 280x is the first GPU, simple launch it without specifying a device: Code: ./minerd -u workername -p workerpass If it is no the first device (in case you have more GPUs on the same machine), first list the devices: Code: ./minerd --list-devices it should show you the device numbers, like this: Code: Platform 00: AMD Accelerated Parallel Processing Take note of the right device and run (in this case, the 280x is "tahiti", so device 01): Code: ./minerd -u workername -p workerpass -d 1 DO NOT use -d 0,0 as in your example, this will try to run it twice in the same device and may lead to inconsistencies and out of memory errors. If you want to run on more than one device, in my case on "Cedar" and "Tahiti", run as follows: Code: ./minerd -u workername -p workerpass -d 0,1 You can also use the gpu version to run o CPU, use: Code: ./minerd -u workername -p workerpass -a metiscpu As for your later question: what Steps size is good for 280x ? The default step size (19) should be excelent for 280x. less than 19 might make it slow, and more than 21 will take too long to complete each step, with no performance improvement. |
