I will continue using Intel. I'm curious whether you have any insight into what about your workload fared poorly on the AMD chip. these particular models are similar in their cache and clocks; I wonder whether your experience could be due to, for instance, code that spends all its time in cache misses (where temporal inteleaving with HT might work well.) or whether the AMD chip was not adequately cooled, preventing it from scaling its clock. or whether your test was hurt by the now well-known module/L1 scheduling issue. specrateFP results seem to indicate AMD is not doing badly. of course, the Intel system is also more expensive. _______________________________________________ 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
