OpenCL device matching slot 0 not found,

[cl0h]

Hi all,
I want to do my bit in the fight against COVID 19 / SARS CoV2 and I'm trying to get folding working on two GPUs on Fedora 31. See spec below. I installed the RPM Fusion NVidia drivers. I removed CPU folding and added 2 GPUs. I got these errors in fahclient log:

Code: Select all

09:07:59:ERROR:WU00:FS00:Failed to start core: OpenCL device matching slot 0 not found, try setting 'opencl-index' manually
09:10:01:ERROR:WU01:FS01:Exception: Failed to connect to 192.0.2.1:80: Connection timed out

[/code]
Please tell me what other info / log output is needed.
Regards
C.

Someone else with experience with Fedora may be able to help some of your problem, and there are also some recent posts from persons setting up on Fedura that might be useful to you.

One thing I can point out, the Quadro FX 1800 is too old to use and is no longer supported as it is based on the Tesla chip architecture. The NVS 310 may work as it is based on Fermi which is the minimum requirement. I can not find information quickly on whether double precision calculations are supported on the NVS 310, if not it also is no longer supported.

If that is the case, then WU requests are redirected to an address that was planned for a new version of the client to provide that feedback, and to keep from adding to the load on the Work Servers.

Thanks for the response. I will investigate CPU folding as an alternative.
