Software for the Parallel Conservative Scheme for the Shallow Water Equations

Abstract

This report contains the host and node programs for the solution of the shallow water equations with topography on an INTEL iPSC/2 hypercube. Finite difference scheme conserving potential enstrophy and energy is employed in each subdomain. In this report we supply software for the numerical solution of the shallow water equations on an INTEL iPSC/2 hypercube. The method is based on domain decomposition with overlap. Finite difference scheme is used to solve in each subdomain. The scheme conserves potential enstrophy and energy. The efficiency of the algorithm is 81% when using 8 processors.
