You're absolutely right. While i absolutely respect HPL (and it's creators) as a valid benchmark and we do use it is a generalization on expected performance. It doesn't give us any real indication on the maximum potential of a computers performance with respect to our codes. _______________________________________________ Beowulf mailing list, [email protected] sponsored by Penguin Computing To change your subscription (digest mode or unsubscribe) visit http://www.beowulf.org/mailman/listinfo/beowulf
