Salut Sylvestre!
Thanks for the superspeedy follow-up!

That would be wonderful. I'd be happy test source packages etc pp

Not sure I fully understand the question. A lot of _tuning_ happens at
_build time_ just like Atlas. That is where the tuning comes from.
What Goto BLAS shares with MKL (and does better than Atlas) is the ability to
_select the number of cores at run-time_. Is that what you meant?
All 'hard' questions I suggest you direct in a friendly email to Ei-ji who
knows so much more about all this than I do...
Cheers, Dirk
