This is great news, but I have a question.  Given that ATLAS by
definition tunes for CPU and memory microarchitecture (at least, and
thus will generally be different in a matrix for a PPro, PII, PIII,
Celeron, Athlon, Alpha (per MHz) as row identifiers and EDO, PC66,
PC100, PC133 (etc) as column identifiers) what is it prebuilt for?

a factor of 2-3 difference in performance in linear algebra calls, and
is a lot cheaper than buying 2-3 times as many nodes:-)...

I ask because I need ATLAS (and of course the actual LA packages) for
all of the above to properly cover our base of installed systems.
