A commercial compiler - Intel / Pathscale /Portland will always give you better performance from an application. The guys who work on those compilers care about optimization. And think about this - if an optimizing compiler can give you 20 percent faster code you effectively can save buying 20% more hardware, and are saving on 20% power and space. _______________________________________________ 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
