Synopsis

Having recently shown that high-order unstructured discontinuous
Galerkin (DG) methods are a spatial discretization that is well-matched
to execution on GPUs, in this talk I will explore both core and
supporting components of high-order DG wave solvers for their
suitability for and performance on modern, massively parallel
architectures. Components examined range from simple linear forward
solvers to shock capturing schemes and time steppers, for which I will
present a selection of design considerations, algorithms, and
performance data.
