Linux x86_64
For a couple of weeks now I have two pc's that cant get any GPU tasks, 3 other pc's get them just fine.
Here is the startup code, you can see it's requesting NVIDIA tasks but it never gets any.
Before a couple of weeks ago both pc's were executing NVIDIA tasks just fine.

Message 75051 - Posted: 12 Feb 2023, 6:52:59 UTC - in response to Message 75050.  

MilkyWay tasks are OpenCL, not CUDA, and BOINC hasn't spotted OpenCL drivers so you need to install the NVIDIA OpenCL stuff.

Not sure how to do that on your openSUSE - I think making sure you have an OpenCL ICD loader (ocl-icd-linopencl1 on my Ubuntu systems) should do the trick...

You can check the existing OpenCL devices with clinfo...

Cheers - Al.

P.S. the best place for queries like this is probably the Number Crunching forum or the Unix/Linux forum -- you might've got an answer from an openSUSE user! :-)

Yep, libOpenCL.so (opencl client driver bindings) was missing, installing it fixed things on both systems - thanks
Apparently some update removed the lib, why? i don't know, but now its fixed
