I wouldn't make this comparison. The Cray 2 local store was much easier to use than Cell's software-managed memory. And almost no one actually used the Cray 2 local store. Which ought to be a lesson learned. Another example of a modern machine with software-managed local store is QCDOC. Again, this is the easy-to-use kind, very unlike Cell. -- greg _______________________________________________ Beowulf mailing list, [email protected] To change your subscription (digest mode or unsubscribe) visit http://www.beowulf.org/mailman/listinfo/beowulf
