OpenBLAS and CLBlast support

[Fr0d0Beutl1n]

Is there a reason that OpenBLAS and CLBlast are not mentioned in the README?

I compiled it with cmake -DLLAMA_OPENBLAS=1 -DLLAMA_CLBLAST=1 .. && cmake --build . --config Release (on Linux), and it appears to be working as expected.

I am focusing currently cpu + the cuda with cublas variants.

Right now I believe metal, clblast and openblas will work but if I mention it in the readme I am forced to fix problems with them and keep them synchronized with new features.
I can't test metal and I had to focus on one variant - I'm most familiar with cuda+cublas.
clblast won't react to reserved memory or override-gpu flags, so we already move a bit out of support.

We will likely move gradually out of support for some variants, except if someone keeps updating them to stay compatible with new features added. Given how much better Falcon is than Llama it's well possible people will work on keeping their favorite compilation options running.

I can't seem to get past these errors, always compiled without GPU-support. I have cblast installed, but those two files are not on my system?

CLBlastConfig.cmake
clblast-config.cmake

CLBlast is what gives you GPU support. Cmake can't find the config file CLBlastConfig.cmake that would enable it to compile the program with GPU support. The problem you have, is not with ggllm.cpp. Either, you did not install CLBlast correctly, or you specified a wrong path.

On my system (Arch Linux) CLBlastConfig.cmake is in /usr/lib/cmake/CLBlast, and I don't have clblast-config.cmake. The log message you provided states, that you only need one of those two files, which makes sense, considering that I was able to compile it with just one of them. I assume that they are just different names for the same file.

Maybe this helps? If the installation fails for whatever reason, you could just build CLBlast, and then, when building ggllm.cpp, specify the directory where you built CLBlast with -DCMAKE_INSTALL_PREFIX=/path/to/install/directory.

Forgot to answer: try switching off cublas defines, it looks like cublas is being compiled but you want clblast.
