>From the blurb on SGI MPT -(their ICE systems have multirail)
http://www.sgi.fr/WP_MPT_SGI.pdf SGI MPT utilizes multiple InfiniBand rails to perform message pathway distribution and message striping. Message pathway distribution is done by strategically mapping individual routes (source to destination) to the available rails. Since routes are mapped to different rails, more aggregate bandwidth is available in situations where many MPI processes are communicating at the same time. SGI MPT performs message striping by sending portions of large messages on each rail in parallel with the effect of nearly doubling the effective MPI point-topoint bandwidth. _______________________________________________ Beowulf mailing list, [email protected] To change your subscription (digest mode or unsubscribe) visit http://www.beowulf.org/mailman/listinfo/beowulf
