Extend the Future RICH ray tracing tools with a vectorised implementation based on Vc (!123) · Merge requests · LHCb / Lbcom

Christopher Rob Jones requested to merge RichFuture-VectoriseRayTracing into master Mar 07, 2017

Uses CPU capabilities detection at run time to select SSE4/AVX/AVX2+FMA implementations.

AVX2+FMA currently disabled (AVX used instead) until such a time as all build targets support it (requires an updated binutils for SLC6). Decided to also disable this for centos7, even though there it could be built, in order to not introduce potential platform differences.
