I've been trying to run 13b models in kobold. CLBlast's API is designed to resemble clBLAS's C API as much as possible, requiring little integration effort in case clBLAS was previously used. I got boost from CLblast on AMD vs pure CPU. Feb 11, 2010 · When porting the marchine learning framework I use to CUDA, I was very disappointed to see that for the type of operations I’m doing, CUDA is actually slower that CPU code. But it’d be interesting to see when the “crossing over” point is, where the GPU attains higher FLOPS than the CPU (using the same precision). Sep 14, 2014 · Just of curiosity. Apr 19, 2023 · I'm trying to use "make LLAMA_CUBLAS=1" and make can't find cublas_v2. If the dot product performance is compareable it's probably the better choice.
