An MPI Framework for HPC Clusters Deployed with Software-Defined Networking

This talk will present our ongoing work on SDN-enhanced MPI, an MPI framework for HPC clusters equipped with Software-Defined Networking (SDN). The goal of this framework is to improve inter-process communication performance and network utilization through dynamically reconfiguring the interconnect based on the communication pattern of applications. We present the overview of SDN-enhanced MPI and summarize recent achievements including several accelerated MPI collectives as well as a network profiling tool for use with our framework.
