DESCRIPTION;ENCODING=QUOTED-PRINTABLE:ABSTRACT: The understanding of earthquake dynamics is greatly supported by highly resolved coupled simulations of the rupture process and seismic wave propagation.=0AThis grand challenge of seismic modeling requires an immense amount of supercomputing resources.=0AThe increasing demand for parallelism and data locality often requires replacing major software parts.=0A=0AI present a new computational core for the seismic simulation package SeisSol.=0AThe new core is designed to maximize value and throughput of the FLOPs performed in the underlying ADER-DG method.=0AIncluded are auto-tuned matrix kernels, hybrid parallelization up to machine-size and a novel high performance clustered LTS scheme.=0A=0AThe presented computational core reduces time-to-solution of SeisSol by several factors and scales beyond 1 million cores.=0AAt machine-size the new core enabled a landmark simulation of the Landers 1992 earthquake.=0AFor the first time this simulation allowed the analysis of the complex rupture behavior and seismic wave propagation at high geometric complexity.
