The Peano software---parallel, automaton-based, dynamically adaptive grid traversals (2019)
Journal Article
We discuss the design decisions, design alternatives, and rationale behind the third generation of Peano, a framework for dynamically adaptive Cartesian meshes derived from spacetrees. Peano ties the mesh traversal to the mesh storage and supports on... Read More about The Peano software---parallel, automaton-based, dynamically adaptive grid traversals.
Studies on the energy and deep memory behaviour of a cache-oblivious, task-based hyperbolic PDE solver (2019)
Journal Article
We study the performance behaviour of a seismic simulation using the ExaHyPE engine with a specific focus on memory characteristics and energy needs. ExaHyPE combines dynamically adaptive mesh refinement (AMR) with ADER-DG. It is parallelized using t...

A simple diffuse interface approach on adaptive Cartesian grids for the linear elastic wave equations with complex topography (2019)
Journal Article
In most classical approaches of computational geophysics for seismic wave propagation problems, complex surface topography is either accounted for by boundary-fitted unstructured meshes, or, where possible, by mapping the complex computational domain...
