* iq1_s: WIP basics * iq1_s: CUDA is working * iq1_s: scalar CPU dot product * iq1_s: WIP AVX2 dot product - something is not right * Fix tests * Fix shadow warnings * Fix after merge with latest master * iq1_s: AVX2 finally works * iq1_s: ARM_NEON dot product. Works, but not very fast * iq1_s: better grid * iq1_s: use IQ2_XXS for attn_output At a cost of 0.04 extra bpw this gives a big improvement in PPL. * iq1_s: Metal basics Dequantize works, but not dot product * iq1_s: Metal works, but quite slow As usual, Apple Silicon does not like the code I write. * iq1_s: Tests * iq1_s: slightly faster dot product --------- Co-authored-by: Iwan Kawrakow <iwan.kawrakow@gmail.com> |
