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…

Role-Oriented Code Generation in an Engine for Solving Hyperbolic PDE Systems
Jean-Matthieu Gallard, Lukas Krenz, Leonhard Rannabauer +2
The development of a high performance PDE solver requires the combined expertise of interdisciplinary teams with respect to application domain, numerical scheme and low-level optim…
