Phenomena in the performance behaviour of high-performance computing (HPC) applications can stem from the HPC system itself, from the application’s code, but also from the simulation domain. In order to analyse the latter phenomena, we propose a system that visualizes profile-based performance data in its spatial context, i.e., on the geometry, in the simulation domain. It thus helps HPC expert...
