One core gets each interrupt. cat /proc/interrupts to see how this works in your system. > I personally like the concept that Level 5 Networks used in conjunction > with their GigE cards - user space drivers. This is how everyone does their EtherNot devices: InfiniPath, Myrinet, Quadrics, yadda yadda. Then the next question is, why are you bothering with TCP? With EtherNot, you can avoid all of the interrupts. A typical InfiniPath system only has a couple of interrupts after running for weeks; bringing the link up causes a couple. MPI doesn't cause any. -- greg _______________________________________________ Beowulf mailing list, [email protected] To change your subscription (digest mode or unsubscribe) visit http://www.beowulf.org/mailman/listinfo/beowulf
