Chapter 21
High performance seismic simulations
Abstract
Results using SeisSol, which simulates wave propagation and dynamic ruptures based on the arbitrary high-order accurate derivative discontinuous Galerkin method, on Knights Landing are discussed. The unique combination of the described individual steps allows the acceleration of seismic simulations. Data reorganization and low-level matrix kernel implementations are key.
