From 154e0d75fccf1784fe9ff6fd76a630b66563da3d Mon Sep 17 00:00:00 2001 From: Kawrakow <48489457+ikawrakow@users.noreply.github.com> Date: Sat, 27 Jul 2024 07:55:01 +0200 Subject: Merge mainline llama.cpp (#3) * Merging mainline - WIP * Merging mainline - WIP AVX2 and CUDA appear to work. CUDA performance seems slightly (~1-2%) lower as it is so often the case with llama.cpp/ggml after some "improvements" have been made. * Merging mainline - fix Metal * Remove check --------- Co-authored-by: Iwan Kawrakow --- llama.cpp | 19340 ------------------------------------------------------------ 1 file changed, 19340 deletions(-) delete mode 100644 llama.cpp (limited to 'llama.cpp') diff --git a/llama.cpp b/llama.cpp deleted file mode 100644 index 169f7d68..00000000 --- a/llama.cpp +++ /dev/null @@ -1,19340 +0,0 @@ -#define LLAMA_API_INTERNAL -#include "llama.h" -
