Folding Forum

Posted: **Sat Aug 08, 2020 1:15 pm**

Hi. I'm trying to fold on Gentoo Linux. I installed foldingathome from sci-biology/foldingathome.

CPU folding worked fine, but GPU doesn't work.

I think I have the nvidia driver and opencl installed, but FAHClient complains about "Failed to start core: OpenCL device matching slot 1 not found, make sure the OpenCL driver is installed or try setting 'opencl-index' manually".

Here's the related log (with download and cpu progress stripped):

Gentoo is not an officially supported Linux distribution, but you might find some workarounds here: viewtopic.php?f=89&t=33333&p=318172

First add the fahclient user to the "video" group.

Please post the first 100 or so lines of your log that explains what FAHClient sees about your System Info and Configuration. You can remove the Download and Progress lines.

Have you installed the proprietary drivers from Nvidia? You need those - the open source Nvidia drivers can't be used for folding. (Linux Mint users get an installer for the proprietary drivers, but most other users have to use Nvidia's webside to download a package or installer for it.)

Are you using a laptop with a GTX 1050 in it? You might have to disable the integrated graphics.

Have you installed the proprietary drivers from Nvidia? You need those - the open source Nvidia drivers can't be used for folding. (Linux Mint users get an installer for the proprietary drivers, but most other users have to use Nvidia's webside to download a package or installer for it.)

Are you using a laptop with a GTX 1050 in it? You might have to disable the integrated graphics.

I think I ran into a different problem other than this one. This bug has been fixed by Gentoo, and now foldingathome user is in video group by default.

The log has been updated.

I think I'm using the proprietary drivers installed from Gentoo's package manager.

I'm using a desktop computer.

Thanks for helping

What is the output of the "clinfo" command run as root? If it doesn't show any cards, you might need to add some OpenCL development files. If clinfo lists something as root, but not as the fahclient user, it's likely a permissions issue still. Does your system have a "render" group?

Both root and foldingathome user can get lots of output from clinfo, but I got a segmentation fault with the foldingathome user.

The foldingathome user doesn't have a shell per default. Temporarily edit /etc/passwd and give the foldingathome user /bin/bash as a shell. Then you can test again. Remember to set the shell to false afterwards.

I set it to /bin/bash, but the output didn't change.

Looks like, from the thread I listed above, that you still have to run FAHClient as root(?!) on Gentoo. That might be the same error that gives a segfault when you run clinfo as the fahclient user.

Manfred.Knick wrote:Gentoo bugs #714160 (1) and #712744 (2):

- In order to exploit CUDA, enable USE=+uvm for x11-drivers/nvidia-drivers-440.64:0/440
- No need to edit /opt/foldingathome/config.xml manually:
- Team 11298 ("Gentoo Linux Users Everywhere") already set as default
- (!) Do not use "/etc/init.d/foldingathome start" and do not "rc-update add foldingathome default" right now

- (!) instead (as root, unfortunately) start /opt/foldingathome/FAHClient

I would normally not recommend running FAHClient as root, especially since it auto-downloads software (the folding cores), but if you don't care about your system, you could try to stop FAHClient, and just cd into foldingathome's home directory and run FAHClient with sudo and see if it picks up OpenCL.

Edit: This appears to me to be something wrong with Gentoo's setup. Maybe you're better served with the official Linux download and just extracting the executables from that?

Oops, I found that eselect-opencl is not deprecated, but conflicting with opencl-icd-loader. I switched to eselect-opencl, but the problem persists.

Code: Select all

 ag@AprilGrimoire  /home/ag   eselect opencl list                                         23:29:47 
Available OpenCL implementations:
  [1]   nvidia *

Did running as root help? If not, I wonder if you'll need to install a full CUDA development environment to get the correct OpenCL files.

Running as root didn't help.

I've installed nvidia-cuda-sdk with opencl use flag enabled, but it didn't help either.

Remove the MESA OpenCL platform.

Crossover depends on it. Can I run foldingathome with it kept?
