Parallel Algorithm For Solution Of The Node Equations On River Network
Abstract:In order to solve large linear equations in river flow calculation, this paper introduces a parallel algorithm of SOR iteration method based on MPI. In addition to represent the process of parallel computing minutely, the author test and analyze the final results. The results show that the parallel algorithm has good parallel efficiency. And the method is a universal program, which can easily be extended to the parallel computing of other models.
Keywords: river flow calculation linear equation SOR parallel computing
