Abstract

The HPC landscape is undergoing significant changes and will become increasingly complex over the coming years. The assessment of the real-life performance of HPC systems through application benchmarking is thus becoming ever more important. The Distributed European Infrastructure for Supercomputing Applications (DEISA) is an EU-funded project that tightly couples high performance computing resources in eleven supercomputing centres in Europe. In a collaboration between DEISA, Cray and IBM, this study investigates the effect of performance tuning of selected scientific applications from the DEISA Benchmark Suite on current hardware. The aim is to highlight current knowledge gaps and find the focus for training and education going forward. This includes understanding both science- and user-driven requirements for default machine configurations.
