基于MPI的二维泊松方程差分并行实现与测试
A simple parallel implementation of two-dimensional poisson equation and test of difference
摘要
Abstract
Message-passing is a widely used cluster environment for parallel programming model. With a simple two-dimensional poisson equation for the first boundary value problem of the typical difference scheme, this paper used five-point difference discretization and the implementation of the Jacobi iterative method for solving such equations in MPI parallel environment. Actual tests showed that such equations in a certain scale of the problem, the parallel algorithm of it had good speedup and parallel efficiency.关键词
