Type of Change
feature or bug fix or documentation or others: feature
API changed or not: yes
support S3_CLIP quant-type in BesTLA
supported ISA: AVX512F/AVX512_VNNI/AMX_INT8/AMX_BF16
note: not support most of client CPUs without bit_mask instructions.
usage:
auto ptr = kernel.createStorage(n, k, blocksize, BTLA_DTYPE::S3_CLIP, BTLA_DTYPE::F32, BTLA_DTYPE::F32, false);Description
nearly 17% next-token perf improvement compared with int4(gptj model, gs=128, int8-cmpt)
