But It did Not Work, just went to CLI after install and boot, so No idea why that is, so Went to in more manual way to what Live Boot install, installs, just no at least at first working OpenCL, but did with rusticl and plus some edits, just need this in /etc/profile.d/ with name of rusticl.sh and with this in it, "
export RUSTICL_ENABLE=radeonsi
export RUSTICL_FEATURES=fp64
export OCL_ICD_VENDORS=rusticl.icd " also 2 text files mesa.icd changed too mesa.icd.disabled and this instead, now for me on an RX550 amdgpu I need this specifically in the file named rusticl.icd with libRusticlOpenCL.so.1. also to be safe, I added in grub this as well and after quiet splash and let me just state that for some reason something installed and before I made this change, tried to install some nvidia stuff, not to sure, but for me I want to avoid conflicts so added in /etc/default/grub after
quiet splash rd.driver.blacklist=nouveau modprobe.blacklist=nouveau rd.driver.blacklist=nvidia modprobe.blacklist=nvidia Now I can confirm that my way of OpenCL does work, the problem is the devs don't consider rusticl way of it. And if any devs see this, the AMD site for drivers are really terrible, If you can get it to work, great. But not everyone can. I even Used clpeak, so yea it does work with rusticl way as seen part of here, " ~$ clpeak

Platform: rusticl
Device: AMD Radeon RX 550 / 550 Series (radeonsi, polaris12, ACO, DRM 3.61, 6.14.0-36-generic)
Driver version : 25.0.7-0ubuntu0.24.04.2 (Linux x64)
Compute units : 8
Clock frequency : 1183 MHz "" after this just did the computation. I would like tlo use OpenCL and please consider this weird AMD website driver situation versus from how each distro able to make it work on their flavs, I was glad I could game right after install and reboot but then many don't consider rusticl. I got it to work, yes can be alil frustrating. and In my case the export RUSTICL_ENABLE=radeonsi is specific to my card as its a bit more older compared to say RDNA 1 to 4 If I remember correctly, which are newer. Not to sure what will be needed for that. Just trying to help though with at least for me to get this to work, hoping that Devs and opencl projects like this will also make it happen for us rusticl users as well..
