New Optimized OpenCL Kernel for Myriad-Groestl

18, Oct 2015

sgminer-myriad-groestl-optimized-kernel

A user called ghostlander on Bitcointalk has released a new optimized OpenCL kernel for the Myriad-Groestl algorithm that is supposed to give you at least 10% increase in performance compared to the public kernel available, but in reality the hashrate increase is much more significant. We have tested the new kernel with a Radeon R9 280X GPU and got over 31 MHS while with the latest sgminer kernel we have managed to get only about 10 MHs or with other words about 200% increase using intensity of 19. You can try to increase the intensity a bit more if your GPU manages to handle it ot squeeze a bit more extra performance as well over 19. So if you are mining a coin using the Myriad-Groestl such as DigiByte or Myriad on AMD hardware you should definitely consider upgrading the kernel (just replace the old .cl file with the new one) to get a lot of extra performance and increase your hashrate.

New grs-sgminer Fork with Optimized GroestlCoin Performance

18, Jun 2014

grs-sgminer-fork-windows

If you are mining GroestlCoin (GRS) with AMD GPUs, you might want to check out this new fork of sgminer called grs-sgminer by srcxxx that comes with optimized kernel for higher performance for mining GRS and DiamondCoin (source). Do note that the miner may not work on older AMD GPUs and the performance may vary based on the video driver version you are using, people are reporting various results with different drivers. The windows binary we have compiled and provide below did give us a performance of about 15 MHS on a Radeon R9 280x GPU running the latest beta drivers 14.6 from AMD, but your results may vary. You are welcome to try it out and report your performance and experience with different GPUs and driver version in the comments below.

Official ccMiner 1.2 with X13 and Diamond Groestl Support Now Available

15, Jun 2014

ccminer-1-2-windows

The ccMiner Nvidia CUDA miner has just been updated to version 1.2 with the source code getting support for the community contributed X13 and Diamond Groestl support. We have compiled a windows binary version from the source that includes the recently released optimizations called “Killer Groestl” that improves the performance of Groestl and all coins that use the algorithm supported by ccMiner. If you are using tsiv’s fork of ccMiner for mining X13 then it is recommended to download this new update as it will bring an extra performance improvement in x13 mining hashrate. Our tests show that on a GeForce GTX 750 Ti you can expect to get from about 1700 KHS to close to 2100 KHS mining X13 with the new ccMiner 1.2 as X13 does rely on Groestl as well.

Do note that the windows binary you can download below is compiled for Compute 3.0 and Compute 3.5-5.0 cards (32-bit version only), so it will not work on older cards. If you are unsure what version of Compute does your video card support check the included GPU Compute Capabilities List file. It is also compiled with Visual Studio 2012, so if you do not already have Visual C++ Redistributable for Visual Studio 2012 you will have to download and install it, otherwise you may be getting error for a missing DLL library.
