COMMIT: http://review.gluster.org/12837 committed in master by Pranith Kumar Karampuri (pkarampu) ------ commit 593b7a83f7408e59ab7b3ef7dfc4fe4096d6e3cd Author: Xavier Hernandez <xhernandez> Date: Tue Dec 1 11:50:54 2015 +0100 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.
