An evaluation of network architectures for next generation supercomputers

Abstract

We survey network topologies, in particular networks with full all-to-all bandwidth scaling. For more detailed study, we select several recently introduced, promising networks that are cheaper than a 3-level Fat-tree. Through a combination of analysis and simulation on selected supercomputer workloads, we compare these networks according to desirable network properties such as robust performance, low cost, and partitionability. We conclude with observations for future systems.
