- golang-github-minio-blake2b-simd-dev: Fast hashing using pure Go implementation of BLAKE2b with SIMD instructions
BLAKE2b-SIMD Pure Go implementation of BLAKE2b using SIMD
optimizations. Introduction This package was initially based
on the pure go BLAKE2b (https://github. com/dchest/ blake2b)
implementation of Dmitry Chestnykh and merged with the (cgo
dependent) AVX optimized BLAKE2 (https://github. com/codahale/ blake2)
implementation (which in turn is based on the official implementation
(https://github. com/BLAKE2/ BLAKE2). It does so by using Go's Assembler
(https://golang. org/doc/ asm) for amd64 architectures with a golang only
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_amd64.s, compressAvx_ amd64.s, and compress_generic.go
respectively.
