Application based network performance testing
Robin Pinning · 2007
The large scale modelling of many physical phenomena increasingly requires the model to be of a size that is too large for one HPC resource.MPICH-G2 is a grid-enabled MPI implementation that allows the coupling of multiple machines for the running of a single MPI-based application.This work aims to show how the use of light-switched optical networks, such as UKLight, affect codes of this class by running a series of benchmarks using the Intel MPI benchmarking suite Lighting the Blue Touchpaper for UK e-Science -Closing Conference of ESLEA Project March 26-
