[Numpy-discussion] OpenBLAS on Mac

[Olivier Grisel]

Indeed I just ran the bench on my Mac and OSX Veclib is more than 2x
faster than OpenBLAS on such squared matrix multiplication (I just
have 2 physical cores on this box).

MKL from Canopy Express is slightly slower OpenBLAS for this GEMM
bench on that box.

I really wonder why Veclib is faster in this case. Maybe OSX 10.9 did
improve its perf...
