Performance comparison between two-sided MPI, MPI-3 RMA and OpenSHMEM for a particle cluster algorithm

Year: 2025

Type: article

Abstract: We present a performance benchmark of a parcel cluster algorithm for N-body simulations that uses either MPI point-to-point, MPI-3 remote memory access (RMA) or OpenSHMEM communication for the nearest-neighbour graph splitting step. The benchmarks are performed on ARCHER2 (Slingshot 10 interconnect), Cirrus (InfiniBand interconnect) and hotlum (Slingshot 11 interconnect).
