> 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.
