I disagree. The tests integration sucks and some of the tests themselves are poorly written. For example, last time I looked, bench_lat_bw measures *8* half-RTTs with MPI_Wtime(). If your MPI_Wtime() is not using cycle counting instructions by default (which is not portable), then you are screwed.
Getting the timing right is benchmarking 101. Patrick _______________________________________________ Beowulf mailing list, [email protected] To change your subscription (digest mode or unsubscribe) visit http://www.beowulf.org/mailman/listinfo/beowulf
