Exploiting the Space Filling Curve Ordering of Particles in the Neighbour Search of Gadget3
Antonio Ragagnin, Nikola Tchipev, Michael Bader +2
Gadget3 is nowadays one of the most frequently used high performing parallel codes for cosmological hydrodynamical simulations. Recent analyses have shown t\ hat the Neighbour Sear…
Influence of A-Posteriori Subcell Limiting on Fault Frequency in Higher-Order DG Schemes
Anne Reinarz, Jean-Matthieu Gallard, Michael Bader
Soft error rates are increasing as modern architectures require increasingly small features at low voltages. Due to the large number of components used in HPC architectures, these…
Studies on the energy and deep memory behaviour of a cache-oblivious, task-based hyperbolic PDE solver
Dominic E. Charrier, Benjamin Hazelwood, Ekaterina Tutlyaeva +5
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 a…
Efficient implementation of ADER discontinuous Galerkin schemes for a scalable hyperbolic PDE engine
Michael Dumbser, Francesco Fambri, Maurizio Tavelli +2
In this paper we discuss a new and very efficient implementation of high order accurate ADER discontinuous Galerkin (ADER-DG) finite element schemes on modern massively parallel su…
A simple diffuse interface approach on adaptive Cartesian grids for the linear elastic wave equations with complex topography
Maurizio Tavelli, Michael Dumbser, Dominic Etienne Charrier +3
In most classical approaches of computational geophysics for seismic wave propagation problems, complex surface topography is either accounted for by boundary-fitted unstructured m…
