Sun has recently released their compilers under an opensource license for
Linux as well (Sun Studio Express or something), including their perflib -
which includes Blas and Lapack. Has somebody tried how that combination
performs, compared to Intel MKL or Atlas? I think they are free even for
commercial use.

Just a thought...
