Abstract:

Interconnection network is one of the most important infrastructures in high performance computing systems (HPC). Network topologies determine the scalability of HPC interconnection networks. In this paper, we study several typical HPC topologies, and conduct extensive performance eva- luation using our in-house large-scale interconnection network simulator. We compare the performance of different topologies by varying different configuration settings, including traffic patterns and routing algorithms.
