Abstract

With the development towards strong-scaling in High Performance Computing (HPC), many HPC applications become communication-bound. One of them is the HPC Molecular Dynamics Simulation library FMSolvr, which we are currently revising. In order to optimize communication, one could improve or develop new communication protocols, but in this work we are focusing on problem-specific communication algorithms. We found two promising candidates, the so-called Shift and what we call the Team Shift algorithm. In this work we present an analytical model for the Shift algorithm and verify it. Our model is based on the Hockney communication model and therefore only needs the two Hockney parameters α and β as input, so it can be used on any network where the Hockney model is applicable.
