The project ASCETE (Advanced Simulation of Coupled Earthquake-Tsunami Events) forms an interdisciplinary research consortium that will couple advanced simulation technologies for earthquake rupture dynamics and tsunami propagation to understand the fundamental conditions of tsunami generation. The main objective is to study the interaction of undersea earthquake rupture mechanisms, resulting ocean bottom displacements, and the corresponding sea level disturbance and subsequent potential tsunami generation. Within ASCETE, our subproject will study the optimization of the parallel performance of the respective simulation software packages (SeisSol for dynamic rupture; sam(oa)² for tsunami propagation), in particular questions of efficient memory access on shared-memory nodes (cache efficiency, NUMA effects)and efficient load balancing on large numbers of cores. The latter will include how to level load imbalances caused by locally different time-step sizes (in the ADER-DG method used by SeisSol) and how to optimize parallel adaptive mesh refinement for tsunami simulation.
