[gentoo-science] benchmarking

Hi Andrea,

that's an interesting little project. I gave your suite a little try but it
broke down for me. I tried both as a normal user and root. I am also confused
as to where the results will be stored. I am guessing I didn't find any because
my test broke down.

Here is what happened:
python main.py cblas cblastests.in axpy axpby rot matrix_vector atv symv syr2
ger trisolve_vector matrix_matrix aat trisolve_matrix trmm
