Quantifying performance benefits of overlap using MPI-2 in a seismic modeling application
2010
Proceedings of the 24th ACM International Conference on Supercomputing - ICS '10
AWM-Olsen is a widely used ground motion simulation code based on a parallel finite difference solution of the 3-D velocitystress wave equation. This application runs on tens of thousands of cores and consumes several million CPU hours on the TeraGrid Clusters every year. A significant portion of its run-time (37% in a 4,096 process run), is spent in MPI communication routines. Hence, it demands an optimized communication design coupled with a low-latency, high-bandwidth network and an
