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.
