Thanks Greg. A somewhat naiive question I suspect. What's the best way to test the "memory bandwidth sensitivity" of my code? Given the fact that I have only the AMD Opterons available currently. Any active / passive tests that can throw some metrics out at me? I don't think our codes have been very well profiled in the past and this might be the first time we are approaching this process so rationally. -- Rahul _______________________________________________ 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
