消息传递是一种广泛应用于集群环境下的并行编程模型.针对简单二维Poisson方程的第一边值问题的典型差分格式,在MPI并行环境下,使用五点差分离散和雅可比迭代法实现了此类方程的并行求解.实际测试表明此类方程在一定问题规模下,其并行算法具有很好的加速比和并行效率.%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.
