For those of you interested in this topic, there's an interesting article by Patrick Geoffrey in HPCWire entitled "A Critique of RDMA".
http://www.hpcwire.com/hpc/815242.html (you might have to be a subscriber, but I'm sure Patrick would send you a copy if you ask.) It's basically a critique of why SEND/RECV is better for MPI implementations than PUT/GET. Even if you don't agree with him, it's good reading. For motivation, you might want to note that most of the SEND/RECV-based products mentioned achieve better MPI 0-byte latency than IB Verbs-based MPI implementations. While I don't agree with everything Patrick says, this does get back to my point that I've run into many people who assume that PUT/GET is always the right way to do things. And it isn't. -- greg _______________________________________________ openib-general mailing list openib-general@openib.org http://openib.org/mailman/listinfo/openib-general To unsubscribe, please visit http://openib.org/mailman/listinfo/openib-general
