While sgemm/tinyblas was designed to speed up prompt processing using tiled matrix multiplications, llama.cpp also calls it for inference as a 1x1 computation. Personally I think it makes more sense for us to use our dedicated
ggml_vec_dotfunctions for the inference dot products and leave sgemm for prompt processing only. We can optimize each one for its respective purpose and so forth.See my PR #8049 for an example where sgemm has faster prompt processing while
ggml_vec_dothas faster inference.
