AMD hashrate issue multiple GPUs single process 1.2.5
seravitae opened this issue · 3 comments
On RX570 AMD cards, using "ALL" for all gpus on a single thread gives a hashrate of 178MH/s per card.
Spawning a single process using successive 0, 1, 2, 3 (one process per gpu) the hashrate is >1.4GH/s per card.
There is either a math problem in the display of hashrate (appears to be divided by the number of cards) or something else is wrong.
AMD asynchronous kernel not yet optimal. Single process each AMD GPU best workaround until fixed.
Is there any progress about this problem? I am struggling to open 6 instances with the Intel G3930 CPU.
IP has reported that Windows 10 with drivers 18.3.4 adrenaline, gpu compute mode is running 6 rx580 at 1.8gh/s on a single instance of veominer with the new kv=5 and sk=2 arguments in veominer 2.3.
Closing bug as fixed
