glusterfs.git/xlators/cluster/ec/src/ec-code-avx.c, branch v3.9.0rc2 cluster/ec: Add support for hardware acceleration 2016-09-10T02:19:13+00:00 Xavier Hernandez xhernandez@datalab.es 2015-12-01T10:50:54+00:00 05505c86e02a01ccd4ba2752de2bea4ebd9385a6 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. >Change-Id: I26c75f26fb4201bd22b51335448ea4357235065a >BUG: 1289922 >Signed-off-by: Xavier Hernandez <xhernandez@datalab.es> >Reviewed-on: http://review.gluster.org/12837 >Tested-by: Pranith Kumar Karampuri <pkarampu@redhat.com> >Smoke: Gluster Build System <jenkins@build.gluster.org> >NetBSD-regression: NetBSD Build System <jenkins@build.gluster.org> >CentOS-regression: Gluster Build System <jenkins@build.gluster.org> >Reviewed-by: Pranith Kumar Karampuri <pkarampu@redhat.com> BUG: 1374841 Change-Id: I83731663922ed11ca84536deab5737463416e1e0 Signed-off-by: Pranith Kumar K <pkarampu@redhat.com> Reviewed-on: http://review.gluster.org/15455 Smoke: Gluster Build System <jenkins@build.gluster.org> NetBSD-regression: NetBSD Build System <jenkins@build.gluster.org> CentOS-regression: Gluster Build System <jenkins@build.gluster.org> 
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.
