1080 Nvidia GPU not available - Fedora 31

[GEI]

Installed client & control rpms, opencl & cuda are both installed along with the newest Nvidia drivers for Fedora 31

FAH continues to log "GPU not available" error.

Any ideas on what to track down to get GPU working with FAH?

Welcome to the folding@home community driven support forum.

First, did you reboot after installing the drivers?

If yes then open a terminal and type the following then post the output here:
FAHClient --lspci

rest are Intel cores

rebooted, checked all drivers

I need the GPU to make it usable, otherwise if strictly CPU the core temperatures soar into upper 80c range.

Mod Edit: Added Code Tags - PantherX

See if you can install a package called ocl-icd-opencl-dev ... that's what it's called in debian but I don't have fedora knowledge so you may have to 'dig' a bit.

Once you've got it installed reboot and look at the log to see if the following changes:
23:56:23: GPUs: 0
23:56:23:CUDA Device 0: Platform:0 Device:0 Bus:5 Slot:0 Compute:6.1 Driver:10.2
23:56:23: OpenCL: Not detected: clGetDeviceIDs() returned -1

Also, where did you get the GPU drivers? ie normal repo, graphic drivers repo or nvidia.com/drivers ?

[GEI]

Had mesa-OpenCL installed, installed meas-OpenCL-devel
rebooted
GPU now shows, though OpenCL throughs error and is still -1

I can now "build" a gpu slot, but it just seems to sit there in ready state without picking up the job. Does each slot run its own job?

NVidia drivers are repackaged repo I have been using for years with Tensorflow-gpu successfully.

[Joe_H]

Since the client did not detect a GPU when installed, the configuration has saved that as shown by:

Code: Select all

23:56:23:<config>
23:56:23: <!-- Folding Slot Configuration -->
23:56:23: <gpu v='false'/>
23:56:23:

You can reset that by going to the Expert tab of Configure in FAGControl and entering in the option "gpu" set to the value of "true" as Extra Client Option. Save, and restart the client. You should then be able to set up a GPU slot and get assignments.

[GEI]

I had tried this approach before originally posting. Couldn't find the GPU and reset gpu v=false

After a number of restarts and the mesa-OpenCL-devel install the GPU now has a separate job and is working on it.
Running under medium yields 195507 pts/day while keeping CPU temps under 80c

Thanks for the inputs. I'll leave it set as is for now and let it run for 24hrs and see how it looks.

[bruce]

Are you sure you installed the Nvidia proprietary drivers for Fedora 31i that supports that GPU? It's not uncommon for the non-proprietary drivers to fail to support all the features that FAH needs.

[GEI]

They are Nvidia drivers and Cuda packaged for Fedora. Same as have been using for Tensorflow-gpu

[bruce]

After installing OpenCL and rebooting, what does the new log say where it previously said
23:56:23: GPUs: 0
23:56:23:CUDA Device 0: Platform:0 Device:0 Bus:5 Slot:0 Compute:6.1 Driver:10.2
23:56:23: OpenCL: Not detected: clGetDeviceIDs() returned -1

The FAHCore does not use CUDA explicitly, it uses OpenCL.

[GEI]

OpenCL is ame as above.
GPU shows now as 1080. Its using the Nvidia GPU under Cuda when checked via nvidia-smi and FAHControl. Seems to need higher amount of cores, but memory use is minimal compared to ML/AI

[bruce]

FAH uses the CUDA cores by way of the OpenCL API. FAHCore_22 doesn't need large amounts of GPU memory ... just the highly parallel floating point calculation capability (commonly called 3D calculations).

Please post the first couple of pages of FAH's log.

[GEI]

Will move FAHClient to Docker using a Nvidia base image.

Have to say that while I like the idea of sharing unused resources for research, it needs to be seamless for the volunteer provider.

Nobody will disagree with that concept. FAH is mostly scientists thinking about the Science (which is sound) but FAH's code Development resources are very limited.
