There was a big overhead difference. But the HTX product is retired, and the current DDR PCIe Infiniband chip has overhead similar to the HTX chip. I guess you must run a lot of 2-node 2-core jobs, if you're so concerned with ping-pong latency ;-) ;-) -- greg _______________________________________________ Beowulf mailing list, Beowulf@beowulf.org To change your subscription (digest mode or unsubscribe) visit http://www.beowulf.org/mailman/listinfo/beowulf
