There is a large class of computations which alternate non-overlapped compute and communicate cycles. The average over the lifetime of the process can be ~ 100 MB/s, but that could easily mean it is sending at 1 GByte/s for 10% of the runtime. If you slow down communications by a factor of 4, the app will run a lot slower. -- greg _______________________________________________ Beowulf mailing list, [email protected] To change your subscription (digest mode or unsubscribe) visit http://www.beowulf.org/mailman/listinfo/beowulf
