High parallel efficiency is a important goal in high performance computing (HPC) environments. The seismic simulation software SeisSol and the PDE (partial differential equation) solver engine ExaHyPE both try to achieve this goal. Measuring and comparing the parallel efficiency is important to give a better insight on how far the goal is reached. Two large scale seismic scenarios are used to measure the parallel efficiency. The scenarios were simulated on the same HPC system to provide the equal resources. The performance was then measured with different numbers of cores to provide a wide range of parallel scalability. The measured values for SeisSol were overall on a solid niveau. In contrast, the measured values for ExaHyPE were not satiesfying in the simulated scenarios. The results suggests that SeisSol has a better parallel performance than ExaHyPE. However, ExaHyPE provides other advantages like accessibility, customization and user friendlyness.     «
