How do I effectively control placement when I don't know how big my cache is? How can I cache block loop nests when I don't know how big my cache is? IBM has experience with shared caches on Power4/5 -- and they seem to do a good job of fairly sharing. The rest of us, well, we live in FUD. -- greg _______________________________________________ Beowulf mailing list, [email protected] To change your subscription (digest mode or unsubscribe) visit http://www.beowulf.org/mailman/listinfo/beowulf
