That's weird, given that it's an implementation choice. Presumably Intel is keeping the PathScale tiny rank state as a feature? Reliability, now that's a serious issue! And not one that's trivially fixed for any problem that must be tightly-coupled. -- greg _______________________________________________ Beowulf mailing list, Beowulf@beowulf.org sponsored by Penguin Computing To change your subscription (digest mode or unsubscribe) visit http://www.beowulf.org/mailman/listinfo/beowulf
