A parallel hydrodynamic model for shallow water equations

摘要

A parallel implementation of a finite difference model for solving two-dimensional, time-dependent, open channel flows is presented. The algebraic equations resulting from the finite difference discretization of the two dimensional shallow water flow equations are solved by using explicit MacCormack scheme. The parallel code has been implemented on distributed–shared memory system, by using domain decomposition techniques. The message passing interface (MPI) protocols are incorporated for inter processor data communication. The effect of using two different geometry partitions is investigated. A comparison of the wallclock time of the code between these two partitions is made, and code performances with respect to different number of processors are presented.
