Machine-adapted Methods: High-order DG Wave Propagation on GPUs

Speaker: Andreas Kloeckner, CIMS

Location: Warren Weaver Hall 1302

Date: Nov. 19, 2010, 10 a.m.

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.
