All About BTC, LTC, ETH mining as well as other alternative crypto currencies
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.
Myriad (MYR) is a multiple algorithm crypto currency where you can mine any of the five used algorithms – Scrypt, SHA256D, Qubit, Skein or Myriad-Groestl. Each proof of work algorithm has its own independent difficulty, any algorithm can find the next block. All the algorithms use the same difficulty adjustment method, on average, each algorithm has the same chance of finding the next block. Each algorithm aims for a block generation time of 2.5 minutes, over the five algorithms, a block should be found on average every 30 seconds.
