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:

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.
