ON THE BENEFITS OF USING GPUS TO SIMULATE SHALLOW FLOWS WITH FINITE VOLUME SCHEMES.

M. J. Castro, S. Ortega, M. De La Asunción, J. M. Mantas

Resumen


In this paper, we focus on the efficient implementation of path conservative Roe type high order finite volume schemes to simulate shallow flows. The motion of a layer of homogeneous non-viscous fluid is supposed to be governed by the shallow-water system, formulated under the form of a conservation law with source terms. The implementation of the scheme is carried out on Graphics Processing Units (GPUs), thus achieving a substantial improvement of the speedup with respect to normal CPUs. Finally, some numerical experiments are presented.

 

Key words:    GPUs,    Finite    volume    methods,    shal low-water,    high-order schemes.
