having been a pre-sales engineer in a previous life, i certainly understand (all too well). i don't have anything specific in mind, just poking the bears on the list... but in all seriousness, if someone wanted some unbiased benchmarks run on something i have or have access to, i would do it. that was really all my original point was. _______________________________________________ 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
