On a quad-socket system from a major system vendor with 4x Opteron 2218 (Rev. F, dual-core, 2.6 GHz), I measure 90 - 92 nsec for memory latency, 5.5 GB/s for serial STREAM performance, and 17 GB/s for OpenMP STREAM w/ 8 threads, on 4 sockets. -Tom > > --john > > _______________________________________________ > Beowulf mailing list, [email protected] > To change your subscription (digest mode or unsubscribe) > visit http://www.beowulf.org/mailman/listinfo/beowulf > _______________________________________________ Beowulf mailing list, [email protected] To change your subscription (digest mode or unsubscribe) visit http://www.beowulf.org/mailman/listinfo/beowulf
