Summary:Cray Red Storm is a new distributed memory massively parallel computing platform designed to scale to tens of thousands of nodes. Red Storm has a custom network designed around the Cray SeaStar network interface and router. In this paper, we present an evaluation of three different MPI implementations for Red Storm: the vendor-supported MPICH2 implementation, and two other implementations based on MPICH 1.2.6. We discuss the differences in these implementations and show how various implementation strategies impact performance and scalability.
