From 593b7a83f7408e59ab7b3ef7dfc4fe4096d6e3cd Mon Sep 17 00:00:00 2001 From: Xavier Hernandez Date: Tue, 1 Dec 2015 11:50:54 +0100 Subject: cluster/ec: Add support for hardware acceleration This patch implements functionalities for fast encoding/decoding using hardware support. Currently optimized x86_64, SSE and AVX is added. Additionally this patch implements a caching mecanism for inverse matrices to reduce computation time, as well as a new method for computing the inverse that takes quadratic time instead of cubic. Finally some unnecessary memory copies have been eliminated to further increase performance.
