BLAKE2b-SIMD Pure Go implementation of BLAKE2b using SIMD
optimizations. Introduction This package was initially based
on the pure go BLAKE2b (https:/
implementation of Dmitry Chestnykh and merged with the (cgo
dependent) AVX optimized BLAKE2 (https:/
implementation (which in turn is based on the official implementation
(https:/
(https:/
fallback for other architectures.
.
In addition to AVX there is also support for AVX2 as well as SSE. Best
performance is obtained with AVX2 which gives roughly a 4X performance
increase approaching hashing speeds of 1GB/sec on a single core.
.
BLAKE2b is a hashing algorithm that operates on 64-bit integer values. The
AVX2 version uses the 256-bit wide YMM registers in order to essentially
process four operations in parallel. AVX and SSE operate on 128-bit
values simultaneously (two operations in parallel). Below are excerpts
from compressAvx2_
respectively.
