* more perfo with llamafile tinyblas on x86_64. - add bf16 suport - change dispache strategie (thanks: https://github.com/ikawrakow/ik_llama.cpp/pull/71 ) - reduce memory bandwidth simple tinyblas dispache and more cache freindly * tinyblas dynamic dispaching * sgemm: add M blocs. * - git 2.47 use short id of len 9. - show-progress is not part of GNU Wget2 * remove not stable test
