gcc on Opteron is, relatively speaking, one of the best gcc ports. When PathScale ported back to MIPS, they were able to beat gcc on that processor by a much higher margin than on Opteron or Intel. PathScale was always really good on VASP, by the way, I know we clobbered Intel's compiler on Opteron, don't recall if we were better than Intel's compiler on Intel's chips. -- greg who used to work for PathScale, way back when _______________________________________________ Beowulf mailing list, Beowulf@beowulf.org sponsored by Penguin Computing To change your subscription (digest mode or unsubscribe) visit http://www.beowulf.org/mailman/listinfo/beowulf
