Title Gigabit ethernet - an HPC interconnect? II: Further findings from synthetic benchmark studies and enhanced methods for summarising results
Abstract The Message Passing Interface standard (MPI) is currently the most common programming model deployed by the HPC community to parallelise a wide range of applications in computational science and engineering for distributed memory architectures. We build on a previous in-depth study of the performance of a range of Gigabit Ethernet MPI implementations and switches using the synthetic MPI benchmark IMB. This paper is essentially an appendix to that study, and presents results from benchmarks of a further three typical 1U Gigabit switches deployed in ‘plug and play’ mode, along with an enhanced method for analysing the significant amounts of data produced, which aims to accurately capture performance and summarise findings in a more digestible format.
