Yes, there are application that don't utilize the interconnect and therefore will show the same results on 1GigE and 100GigE. I was referring to the application that do utilize the interconnect, and those are the ones that I test. Anyway, the I/O is not just bandwidth, but also provides latency, CPU overhead and other important characteristics, and all of them need to be considered. _______________________________________________ Beowulf mailing list, [email protected] To change your subscription (digest mode or unsubscribe) visit http://www.beowulf.org/mailman/listinfo/beowulf
