6 years ago When using the driver from https://github.com/RadeonOpenCompute/ROCm#to-install-rocm-with-developer-preview-of-opencl, we were not able to observe the issue. Could you please try it and let us know if there are any issues.

6 years ago I can confirm this issue. I tried to run sgminer-gm with Vega 56 on Ubuntu 16.04.3 LTS.
Here is the log.

6 years ago Can you update the driver to ROCm 1.6.4 it was posted last night at repo.radeon.com Just follow the install instructions at https://rocm.github.io/ROCmInstall.html

Not sure if it's a problem of the driver or of the program, but it compiles alright on amdgpu-pro. Also I'm not sure if this driver is supposed to be faster on ethash ( the blockchain bug? don't have time to research in detail ), but it's actually slower than amdgpu-pro.

6 years ago The only difference between AMDGPUpro driver ROCm driver is AMDGPUpro use proprietary compiler now, and ROCm use fully open source compiler, right now there are app that run faster on the new open source compiler and there that need to tuned since we never run them.
