[SciPy-User] In which numpy modules should MKL be better then ATLAS
Sat Oct 1 04:55:51 CDT 2011
I had a chance to test this sample on different setups on same PC:
import numpy as np
%timeit np.dot(A, B)
because of OS reinstalling.
1x = ATLAS on Linux (reference speed)
2x = MKL with GNU compilers on Linux
2x = MKL with Intel compilers on Windows 7
30x = bare numpy
I didn't plan to do this so I didn't test additional calculations, and I was
using latest version to date for all products.
On Internet I usually find that MKL should outperform ATLAS. I'm curious
what would linalg module testing give, but as said I didn't test it. So in
which modules should user expect impact of MKL over ATLAS? In matrix dot
product obviously not.
