Gferasure

Gferasure is a high performance Galois field library for erasure coding and algebraic signature computation. Gferasure implements constant by region multiplication for erasure coding applications and dot product multiplication for algebraic signatures along with normal Galois field multiplication.
Gferasure utilizes Intel's Single Instruction Multiple Data (SIMD) instruction sets Supplemental Streaming SIMD Extensions 3 (SSSE3), Streaming SIMD Extensions 4 (SSE4), and Advanced Vector eXtentions 2 (AVX2) for Intel processors along with NEON instructions for ARM processors. Gferasure currently supports template implementations for field sizes GF(2^8), GF(2^16), GF(2^32), and GF(2^64).
