Vectorization and Minimization of Memory Footprint for Linear High-Order Discontinuous Galerkin Schemes
Jean-Matthieu Gallard, Leonhard Rannabauer, Anne Reinarz +1
We present a sequence of optimizations to the performance-critical compute kernels of the high-order discontinuous Galerkin solver of the hyperbolic PDE engine ExaHyPE -- successiv…

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…
