Coloured and task-based stencil codes
Benjamin Hazelwood, Tobias Weinzierl
Simple stencil codes are and remain an important building block in scientific computing. On shared memory nodes, they are traditionally parallelised through colouring or (recursive…
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…
Stop talking to me -- a communication-avoiding ADER-DG realisation
Dominic E. Charrier, Tobias Weinzierl
We present a communication- and data-sensitive formulation of ADER-DG for hyperbolic differential equation systems. Sensitive here has multiple flavours: First, the formulation red…
