Title: Architectural Design of Grand Clos Collective Network for Supercomputers
Keywords: Collective Networks, Supercomputers, Grad Clos Architecture, Network Topology Design, OMNET++, Communication Performance Evaluation

Abstract: As modern research and engineering computing methodologies, the demands for high-speed computational resources are growing at a rapid rate. The communication performance of collective network is a crucial factor influencing the communication performance of supercomputers which form the prevailing parallel architecture of modern high-performance computer systems. In this paper we have proposed a modular high-speed switch architectural design and a new collective network design of “Grand Clos” topology to meet the demands of efficient and high-speed communications on supercomputers. The communication performance parameters such as network latency and throughput are evaluated on the basis of parallel simulation models using the framework OMNET++ (C++, MPI) and run on IBM HS22 Blade Center. Analysis and comparison of simulation results has been performed and presented considering the impact of the traffic pattern and the packet size on the communication efficiency of the collective network
