Simulation of Shallow Water systems using

Abstract — We address the speedup of the nume-rical solution of shallow water systems in 2D do-mains by using modern Graphics Processing Units. We have considered a first order well-balanced finite volume numerical scheme for 2D shallow water sys-tems. The potential data parallelism of this method has been identified and an efficient implementation of this scheme to solve one-layer shallow-water systems has been derived for GPUs. Numerical experiments which have been performed on several GPUs show the high efficiency of the GPU solver in comparison with a highly optimized implementation of a CPU solver
