As far as I know, even after installing it, one (and this is one among many) is that you would need a driver that enables openCL. If you're using nVidia, you download the proprietary drivers. If you use AMD, no luck, amd proprietary drivers is only available for Ubuntu derivative, RHEL, and CentOS, you could use ROCm but you'll (as far as you and I probably concerned) need to wait for the Fedora dev team to finish packaging it and then for the Solus dev team to package that for Solus. If you have Intel, I'm guessing that you should use beignet from the repo? I'm not sure tho.
