We consider a hybrid Electronic Packet Switched (EPS) and Optical Circuit Switched (OCS) interconnection network (IN) for future HPC and DC systems. Given the point-to-point communication graph of an application, we present a heuristic algorithm that partitions logical parallel tasks to compute resources and configures the (re-configurable) optical part of the hybrid IN to efficiently serve point-to-point communication. We measure the performance of a hybrid IN employing the proposed algorithm using real workloads, as well as extrapolated traffic, and compare it against application mapping on conventional fixed, electronic-only INs based on toroidal topologies. © 2012 Springer-Verlag.
