1) Message boards : Number crunching : GPU tasks with AMD ROCm (Message 69556) Posted 19 Feb 2020 by Å arÅ«nas Burdulis Post: Open source amdgpu+rocm-opencl is still not usable by Milkyway@home. However open source amdgpu (part of stock Linux kernel) can be combined with OpenCL libraries from AMDGPU-PRO driver (download from AMD). amdgpu-install --opencl=legacy,pal --headless --no-dkms This works with up to the latest Linux kernel, 5.6-rc2 as of today.

3) Message boards : Number crunching : GPU tasks with AMD ROCm (Message 66704) Posted 19 Oct 2017 by Å arÅ«nas Burdulis Post: I have used AMD GPUS with their AMDGPU-PRO drivers. This works with Linux 4.4 and 4.10 (Ubuntu). One can use 4.10 kernel also in the latest Ubuntu 17.10b, but while AMDGPU-PRO installs, it causes some issues with Desktop apps. So I switched to AMD's open source ROCm and its corresponding OpenCL implementation. All seems to works fine, including applications which use OpenCL, e.g. darktable. MW@home GPU tasks however are failing (task log below). Did anyone try ROCm OpenCL? Any ideas on how to 'fix' this? <core_client_version>7.8.3</core_client_version> <![CDATA[ <message> process exited with code 1 (0x1, -255)</message> <stderr_txt> <search_application> milkyway_separation 1.46 Linux x86_64 double OpenCL </search_application> BOINC GPU type suggests using OpenCL vendor 'Advanced Micro Devices, Inc.'

4) Message boards : News : GPU Issues Mega Thread (Message 66703) Posted 19 Oct 2017 by Å arÅ«nas Burdulis Post: I have been successfully running GPU tasks with both AMD (amdgpu-pro) and Nvidia devices, using their provided OpenCL libraries. Yesterday I upgraded one of the AMD workstations to use ROCm and its OpenCL (amdgpu-pro doesn't work on Ubuntu 17.10). GPU device is RX 480 (Ellesmere/Polaris, or 'gfx803' in ROCm). Since then MilkyWay@home GPU tasks are failing. Below is what I see in the task log and part of the clinfo. Let me know if there already is any solution to this or more info is needed. <core_client_version>7.8.3</core_client_version> <![CDATA[ <message> process exited with code 1 (0x1, -255)</message> <stderr_txt> <search_application> milkyway_separation 1.46 Linux x86_64 double OpenCL </search_application> BOINC GPU type suggests using OpenCL vendor 'Advanced Micro Devices, Inc.'
