Arch Linux - GPU folding not working

[Azsorlex26]

Hi. I'm trying to get folding set up on my laptop with Arch and I can't get GPU folding to work (whereas I was able to get it working with Ubuntu). I'm running a rather minimal installation since folding is all I want this computer to do. My laptop has a Geforce 930mx.

I set up FAH using the information found on the AUR page (https://aur.archlinux.org/packages/foldingathome/). In addition to the foldingathome package, I also installed these four packages via pacman: clinfo cuda ocl-icd nvidia. I also made sure that opencl-nvidia was installed (which it was). Finally, I ran sudo nvidia-xconfig, enabled foldingathome.service and foldingathome-nvidia.service, configured FAH, and rebooted my system. Lo and behold, GPU folding isn't folding, but CPU is just fine.

The first thing I checked was the status of foldingathome-nvidia.service, and it turns out it was dead. Below is the output of sytemctl status foldingathome-nvidia. I assume that this has something to do with my driver configuration, but I'm new to Arch and don't know these things. Please help me out.

Quick edit: manually adding in the GPU slot made GPU folding work (foldingathome-nvidia.service still refuses to start), but I don't think it's good to leave things like this since the maintainer explicitly said that foldingathome-nvidia.service needs to be enabled.

Good you got GPU slot finally working. Maybe this thread can give you some hints too?

Thanks for that. I've already done most of the stuff on there, however, there's still more to be done, even during initial setup. I'll try doing a complete reinstall of the system using that guide just to be sure.

Oh and by the way, FAHClient --info didn't pick up my GPU at all, despite commands like nvidia-smi and cat /proc/driver/nvidia/gpus/*/information picking them up.

Nothing. After going through, I still ended up at the same result.


Another quick edit: I read through the comments in the foldingathome AUR page, and there's a comment that reports losing functionality in the latest release as well as three lines from their logs. I encountered almost the exact same thing in the FAHClient --info command. Here it is:

Code: Select all

GPUs: 0
  CUDA Device 0: Platform:0 Device:0 Bus:1 Slot:0 Compute:5.0 Driver:10.2
OpenCL Device 0: Platform:0 Device:0 Bus:1 Slot:0 Compute:1.2 Driver:440.82

But apparently the user commented again saying it was fixed. Looks like I'll just have to contact the maintainer for help.

Your GPU has a high chance, it won't make the deadline.
Considering a GT1030 doing 22 hours on long WUs, a 930 MX would (est) do about 31 hours to finish a WU.
Might work if it's doing 24/7 folding, but pause it, and you might miss the deadline.
