Analyzing available routing engines for InfiniBand-based clusters with Dragonfly topology

Abstract

Dragonfly topologies have gathered great interest as one of the most promising interconnection patterns for the networks at the core of HPC clusters. In this paper, we configure several simulated InfiniBand-based clusters with a Dragonfly topology, and we analyze the performance in these configurations of the routing engines included in the latest release of the InfiniBand Subnet Manager (OpenSM v3.3.19).
