In a similar vain, I would guess that another straw on the back of Road Runner is the fact that it is a unique design with no next generation or upgrade path. I also know that I/O rates are an important design requirement for these machines that, of course, is not addressed by HPL rank (but makes for good news stories). -- Doug -- Mailscanner: Clean _______________________________________________ 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
