Parallel Conservative Scheme for Solving the Shallow-Water Equations

The article of record as published may be found at http://dx.doi.org/10.1175/1520-0493(1993)121To improve the simulation of nonlinear aspects of the flow over steep topography, a potential enstrophyand energy-conserving finite-difference scheme for the shallow-water equations was derived by Arakawa and Lamb. Here a parallel algorithm is developed for the solution of these equations, which is based on Arakawa and Lamb's scheme. It is shown that the efficiency of the scheme on an eight-node INTEL iPSC/2 hypercube is 81 %. Forty mesh points in the x direction and 19 in they direction were used in each subdomain.Office of Naval ResearchNaval Postgraduate SchoolOffice of Naval ResearchNaval Postgraduate Schoo
