I do not know how big the UK audience of this list is but hopefully a few of you may find it very interesting.
* * CSE SEMINAR * * You are invited to attend a CSED Seminar taking place on Tuesday 13 January 2009 in CR1, A Block at 2pm. The Seminar will be given by Brice Goglan from INRIA, France. Title: "High-Performance Message Passing over Ethernet with Open-MX, why and how?" Abstract: Open-MX is a message passing stack that offers the Myrinet Express features on top of regular Ethernet hardware. We will see what problems one can encounter when trying to mimic high-speed network capabilities without having advanced hardware support underneath. Several solutions based on I/OAT copy offload, interrupt affinities, and multiqueue support will be discussed. Finally, we will see how working on intra-node communication in Open-MX also lead to improving large message performance in MPICH2/Nemesis.
