Isn't #1 the simplest to implement? Turnaround on the send queue should be pretty quick, so send performance should be fine. I say do whatever is simplest, and then optimize from there, and to me that means #1 at the moment. What are the reasons to *not* do #1? - Fab _______________________________________________ openib-general mailing list [EMAIL PROTECTED] http://openib.org/mailman/listinfo/openib-general To unsubscribe, please visit http://openib.org/mailman/listinfo/openib-general
