Hello folders,

As topic says having trouble getting set up with the new amd gpu, CPU works fine. Searching the forums leads me to believe that this card is supported at this time, but its not quite clear to me if its in beta, or fully supported now. I have tried setting the gpu and opencl index to 0 instead of the default -1, and also have been experimenting with some of the client-type settings I have spotted in various forum posts - namely I tried both "beta" and "advanced" and neither were successful but not sure if that setting is still needed. currently at idx 0/0 / clienttype beta I get error a lot of bad work unit errors on the GPU, but also : 02:45:13:WU01:FS01:0x22:ERROR:126: Bad platformId size, which I suspect is the main problem.

additional info : default mesa drivers, opencl-amd, and (please let me know if you need to know anything else) :

Thanks for any help you can provide!

GPUs are not placed in "beta" Navi GPUs are fully supported.

When a new project is developed, it is expected to spend some time in "beta" until it has a history of stability. Then it is moved to 'Advanced" which is essentially a release candidate status and then to Full FAH (released to everybody).

The Bad platformId size. error suggests that maybe you do not have the AMD drivers or the OpenCL support properly installed. I'm not a Linux expert, but somebody will come by soon and help you.

The Mesa drivers were mentioned, they do not work for folding. You will need to either use the AMD proprietary drivers or the ROCm drivers. From what some have posted, the ROCm drivers take a bit of work to get installed and configured properly.

Thanks for the initial info bruce and joe_h.

I guess the overall situation is still poor. I tried using the opencl-amd proprietary drivers and immediately ran into errors such as "Forces are blowing up" and ":ERROR:Force RMSE error". After that I spent a few hours compiling the rocm-opencl-runtime drivers. This seemed promising as my first 2 work units seemed to complete - but then I started getting lots of the forces blowing up / RMSE errors again, and havent been able to get another successful WU after the errors started - even after restarting the client or readding the GPU slot config.

I wish I could find the logs but /var/lib/fahclient as written on your website is empty, but I guess this maybe was my fault as the successful ones were cleared via FAHControl while trying to diagnose the second round of errors. You mention that the mesa drivers dont work - but they were installed for those first two successful work units - and I guess I dont understand how the openGL drivers would affect the opencl drivers - they seem to be different things to me, and AFAICT the opengl mesa drivers wouldnt be used for compute, and only for display purposes - but please tell me if Im being slow/misunderstanding something here.

If you can point me to what someone did to get this card running with "a bit of work" Id love to try further, but as it stands - there seems to be something fundamentally amuck with the support of this card still.

Thanks again in advanced for any further info you can provide.
