It doesn't imply that there's an MMU, either. I know that Myricom uses a little lookup routine in software on their nic, which most people wouldn't call an MMU. I don't know what Mellanox does for this, they don't talk much about what's hardware and what's software on their nic. I think Quadrics actually uses the TLB of their risc cpu on their nic for this lookup, but that's just a guess. -- greg _______________________________________________ openib-general mailing list [email protected] http://openib.org/mailman/listinfo/openib-general To unsubscribe, please visit http://openib.org/mailman/listinfo/openib-general
