FLOPs

This is project for awesome code of Mystical available at "how to achieve 4 flops per cycle".

Usage

Just make then run. If you do not have min. Sandy Bridge / AVX CPU avxflops build will fail, but you can still test with sseflops.

Use make CXX=c++compiler to build test with other compiler, the output files will be suffixed with -c++compiler.
