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. > > > Regards > Laura Johnston > > Science & Technology Facilities Council > Daresbury Laboratory > Keckwick Lane > Warrington > WA4 4AD > > Tel: +44 (0)1925 603529 > Fax: +44 (0)1925 603634 >
