OpenCL headers/setup for intel i9 cpu?

Hi,

I have so far managed to get OpenCL up and running on my GTX 760 graphics card, by simply installing the headers found in the AUR. However I have struggled to find headers (or any setup guide) for intel core cpu’s on an arch based system (I run manjaro xfce). I have an i9 10900kf cpu, and when I run clinfo command in the terminal, I get Number of platforms 1 , and my cpu doesn’t show up, only my GTX graphics card does . Is there any information of how to setup opencl for these cpu’s on manjaro/arch?

Ahoj

opencl-headers are in the community repo as an optional dependency of opencl-nvidia & lib32-opencl-nvidia. You should only need those.

What are you installing from the AUR? If it’s intel-opencl, that’s most likely not applicable as it’s a legacy driver for older Intel graphics chips.

Please post your system info as outlined here:

As well as:

pacman -Qs opencl

Yeah, I have the nv repos and CL headers installed, and I’ve been using them to make OpenCL work on my graphics card

But what I now want to know is how to setup OpenCL to run on my CPU, instead of graphics card. But I am not sure what is required to set this up on an arch based system like manjaro (i.e. what repos do I need to install to enable this).

Please post your system info as outlined here:

When I try and run that, I get this:

It appears you would need intel-compute-runtime and should not need anything from the AUR. See GPGPU - ArchWiki

I don’t know what command you ran, but it wasn’t pacman -Qs opencl. Don’t use sudo.

Ok thanks for that. My bad, I ran it as sudo, here is the output:
