GPU Folding under Centos 8.2

It seems that a lot of GPU problems revolve around specific versions of drivers. Though NVidia has their own support structure, you can often learn from information reported by others who fold.

GPU Folding under Centos 8.2

Postby ng0177 » Sat Jul 11, 2020 9:13 am

Mod note: split from older topic - viewtopic.php?f=80&t=34538 - due to change in Linux distro being asked about

On Centos 8.2 w/ NV136 nouveau drivers and
Code: Select all
ocl-icd 2.2.12
installed:
05:39:25:Enabled folding slot 01: READY gpu:0:GP106 [GeForce GTX 1060 6GB] 4372
05:39:25:ERROR:No compute devices matched GPU #0 {
05:39:25:ERROR: "vendor": 4318,
05:39:25:ERROR: "device": 7171,
05:39:25:ERROR: "type": 2,
05:39:25:ERROR: "species": 7,
05:39:25:ERROR: "description": "GP106 [GeForce GTX 1060 6GB] 4372"
05:39:25:ERROR:}. You may need to update your graphics drivers.

Although ocl-icd is installed it is apparently not sufficient for fahclient.

As I remember (I don't use Linux anymore), FAH requires the drivers from Nvidia, for example:

Code: Select all
sudo add-apt-repository ppa:graphics-drivers/ppa
sudo apt-get install dkms build-essential
sudo apt-get update
sudo apt list nvidia-driver

sudo apt install nvidia-driver-NEWEST_VERSION_LISTED


and ocl-icd-opencl-dev
Code: Select all
sudo apt install ocl-icd-opencl-dev


A reboot is required after the -dev installation.

Mod note: next time start a new topic if the subject changes like this from Ubuntu to Centos

Yes, thanks but I changed the title of this thread. The question is now about Centos 8.2

So? Centos is a Linux distro. I don't know for 8.2, as it is really quite new, but I don't think that it should make a difference.

Right. Then, the required package ist ocl-icd-opencl-dev and not just ocl-icd. And -opencl is not (yet) available on Centos 8.2, therefore we need to wait.

Problem solved, here are the instructions:

1) https://fedoraproject.org/wiki/EPEL for dkms and ocl-icd-devel later

2) https://www.nvidia.com/Download/Find.aspx?lang=en-us and install it following http://us.download.nvidia.com/XFree86/L ... river.html whilst also setting selinux to permissive in /etc/sysconfig/selinux.

3) sudo dnf install ocl-icd-devel

4) https://foldingathome.org/beta/

5) sudo /etc/init.d/FAHClient start/stop

No guarantees. This worked for me.
