Re: libacml.a


here's the url to the site that has libgoto, http://www.tacc.utexas.edu/resources/software/,  its quite good, Kazushige Goto has been working on more LAPACK function calls, so it should be interesting to see what they cook up.

ACML is an optimised, proprietary math library by AMD, and is available free
of charge from their web site. By the way, since you are apparently doing
heavy linear algebra calculations, you may want to check also the GOTO
library (I don't remember the URL, google for GOTO blas lapack library and
you will find it). It's a hand-tuned linear algebra library which can give
an appreciable boost, especially on opterons.

Have fun, and please keep me informed on your progress with mpqc: I do heavy
quantum chemical calculations myself, although I currently mostly (ab)use
NWChem and Gaussian, and I'm interested in comparing that with mpqc (I never
tried it yet).
