SeisSol is one of the leading simulation codes for earthquake scenarios, in particular for simulating dynamic rupture processes and for problems that require detailed representation of very complex geometries (fault planes, etc.). Spatial adaptivity in 3D is realized by flexible unstructured tetrahedral meshes, using a high-order Discontinuous Galerkin discretization and explicit time stepping following the Arbitrary high order DERivatives approach (ADER-DG). Due to its high degree of locality the ADER-DG method shows near-optimal speedups on supercomputing architectures.Within this project we will prepare SeisSol for petascale simulations on SuperMUC and on next generation supercomputers, as well as improve SeisSol’s computational efficiency and scalability. The improvements will cover the entire processing flow of SeisSol, from inner, cell-local kernels up to large-scale communication structures and parallel I/O. During our work will not only consider requirements of the hardware but also take the numerical setup into account to minimize the time to solution.
