> 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.
