OpenCL

Howdy, everyone!
I'm trying to verify that my GPU drivers are properly installed, so I've installed clinfo from the repository. If I run either:
sudo clinfo -h sudo clinfo -v
I get meaningful output with either help info, or the program's version number. If I use any other switch, I always get the same error:
root@hooke /home/gumby # clinfo -a Illegal instruction (core dumped)

Does anyone have any suggestions on how to resolve this and/or an alternative way to verify that the OpenCL stack is functioning correctly?

Thanks in advance!

I've found this guide to use for my troubleshooting ordeal. https://bashbaug.github.io/opencl/2019/07/06/OpenCL-On-Linux.html
I find libOpenCL.so.1 installed in various locations:
usr/lib32 usr/lib64 snap/folding-at-home-fcole90/46/usr/lib/x86_64-linux-gnu

As you've probably guessed by now, I'm trying to get the F@H snap package to run on my GPU. It folds just fine on my CPU, by the way.
Not only don't I have a /etc/OpenCL/vendors folder, but the file manager can't find any files with a *.icd extension.

This is just an old machine used for tinkering. It has an antique GTX-570 in it, running the Nvidia 390.132 binary. What do I need to install to have functioning OpenCL support in Solus?
Once I understand how to configure this snap package, I hope to install it on another machine, equipped with a RX Vega GPU, running the open source amdgpu driver. So, if anyone knows if I instead need the AMD binary, or some other combination of packages, I'd be obliged for that information. I've never used OpenCL in Linux before, so I am literally groping in the dark.

Thanks!

GumbyDamnIt I never tried NVIDIA OpenCl on linux, but the corresponding icd file is located at /usr/share/OpenCL/vendors. If the FoldingAtHome snap package needs the icd file to be at a certain location maybe just create a symbolic link from /usr/share/OpenCL/vendors/nvidia.icd to /etc/OpenCL/vendors/nvidia.icd.
OpenCl with the AMD card won't work out of the box. The AMDGPU-Pro driver has OpenCl packages but it is not included in Solus due to licensing issues. Another way is the open source AMD ROCm framework. There is some effort going on to include this in Solus but its not ready yet (See here ). Another way would be using a docker container for OpenCl with AMD.

Contrary to the help page at the Fah web site, recent changes to their client software requires CL 1.2 support, so Fermi cards are no longer supported. I don't think that I'll be purchasing a new GPU, just to run Fah.

I appreciate the info about the current AMD driver situation, thanks very much!!!
