Re: [gentoo-soc] Benchmarking suite - Report 6

[Andrea Arteaga]

I forgot to say that an important feature that has been added to the
script is the capability to generate an HTML report that contains the
plots resulting from the tests.

Moreover, an objective for the next week is the implementation of an
accuracy test for LAPACK, and the support for CBLAS besides BLAS.

Best regards
