Arch Linux User Repository

To be clear, nvidia users need to enable both foldingathome.service and foldingathome-nvidia.service.

@alucryd: working perfectly now with 7.6.9-7 - Thanks :)

FYI, waiting for 60s works on my desktop.

@YanDoroshenko: And thank you for your contribution to solving the issue, whining and being a smartass is always helpful :) I suggest you write to the arch-security mailing list explaining why you think, rather why you know, it's a good idea to run this as root ;)

@keithy: Oh, that's probably me, please try the latest revision.

@Pezlu: Almost there! I've been reading on the f@h forums that there might be some race condition, and just waiting a bit before actually starting FAHClient could be enough to get it working. Can you try adding ExecStartPre=/usr/bin/sleep 60 to the unit file and report back, and maybe play with the delay a bit? I'll do the same on my desktop.

Thanks, great job on keeping my system secure! Yesterday I was able to get the GPU to work running sudo FAHClient, but I'm not anymore, so no more nasty proprietary code running with superuser access.

@alucryd: I just updated to 7.6.9-6 and enabled the foldingathome-nvidia service. I tried to reboot only once, but the issue seems partially solved: OpenCL is detected, while CUDA is not:

19:12:42:           GPUs: 1
19:12:42:          GPU 0: Bus:1 Slot:0 Func:0 NVIDIA:3 GK106 [GeForce GTX 660]
19:12:42:           CUDA: Not detected: cuInit() returned 100
19:12:42:OpenCL Device 0: Platform:0 Device:0 Bus:1 Slot:0 Compute:1.2 Driver:440.82

Restarting the foldingathome service corrects the issue as before:

19:15:36:           GPUs: 1
19:15:36:          GPU 0: Bus:1 Slot:0 Func:0 NVIDIA:3 GK106 [GeForce GTX 660]
19:15:36:  CUDA Device 0: Platform:0 Device:0 Bus:1 Slot:0 Compute:3.0 Driver:10.2
19:15:36:OpenCL Device 0: Platform:0 Device:0 Bus:1 Slot:0 Compute:1.2 Driver:440.82Driver:440.82

@alucryd: My issue actually appears to be entirely to do with foldingathome.service not starting.

During startup I get this error

systemd[1]: multi-user.target: Found ordering cycle on foldingathome.service/start
systemd[1]: multi-user.target: Found dependency on foldingathome-nvidia.service/start
systemd[1]: multi-user.target: Found dependency on multi-user.target/start
systemd[1]: multi-user.target: Job foldingathome.service/start deleted to break ordering cycle starting with multi-user.target/start

Thanks, I hope this doesn't create more confusion

@cubethethird: right apologies, this is more of a hack and I hope to find a better way to initialize opencl for nvidia in the future, but for now I've added it to optdeps

It seems there is now a missing dependency for clinfo that is needed for the foldingathome-nvidia service.

@keithy: I moved the logs to /var/log/foldingathome so it's easier for you guys to access logs.

Also removed the shipped GPUs.txt, looking at the log the download failure has been fixed upstream.

Good job. This package gives some of us options to actually start gpu folding again. Up-voted
