GPU Acceleration of the Discontinuous Galerkin Shallow Water Equation Model with OpenACC
This paper presents porting of a discontinuous Galerkin shallow water equation model (DG-SWEM version 3.0.2), a discontinuous Galerkin solver for hurricane storm surge, to NVIDIA graphics processing units (GPUs). Time-explicit discontinuous Galerkin methods contain a large number of degrees of freedom but have been...
