While Greg's analysis makes sense, one should probably note that transistor-count-driven performance improvement assumptions yield smaller practical benefits today where bandwidth continues to lag and parallel performance improvement is not automatic. A gain in throughput performance is guaranteed by the Moore's Law doubling in the multicore era if your workflow is throughput oriented. ;-) rbw _______________________________________________ Beowulf mailing list, Beowulf@beowulf.org To change your subscription (digest mode or unsubscribe) visit http://www.beowulf.org/mailman/listinfo/beowulf
