I suspect you'd take more of a penalty when doing the IB fabric initialisation and then at wire-up of connections, once that's done it's probably just a quick decision to decide which port to use for data transfers. So yes, maybe slightly slower (assuming the code has some fast path that is used when there is only a single connection to use) but I'd have thought likely not significant. cheers, Chris -- Christopher Samuel Senior Systems Administrator VLSCI - Victorian Life Sciences Computation Initiative Email: [email protected] Phone: +61 (0)3 903 55545 http://www.vlsci.org.au/ http://twitter.com/vlsci _______________________________________________ Beowulf mailing list, [email protected] sponsored by Penguin Computing To change your subscription (digest mode or unsubscribe) visit http://www.beowulf.org/mailman/listinfo/beowulf
