Dragonfly-of-Torus: A Reconfigurable Network Topology for High-Performance Computing

Abstract

We propose a reconfigurable network topology, Dragonfly-of-Torus, for High-Performance Computing (HPC), which embodies the good characteristics of both Dragonfly and Torus topology to accommodate various communication demands. Numerical analysis validates Dragonfly-of-Torus outperforms Mesh, Dragonfly, and Torus in terms of latency (at least 24.4%), throughput (at least 15.28%), and the average path length (at least 17.43%).
