MPI＋OpenMP混合求解偏微分方程

摘要

Finite Difference Method is one of the most important numericaI tooI for soIving PDE.PracticaI probIems can benefit by paraI eI computing of these Finite Difference Equations.A hybrid paraI eI method based on MPI and openmp is studied,and heat conduction probIem is impIemented by this method in this paper.%差分方法是求解偏微分方程的最主要工具之一，并行求解差分方程可以快速解决工程问题。研究了基于MPI与OpenMP混合的并行计算方法，基于该方法测试了稳态传热问题的计算，结果表明，混合并行模式对于提高计算速度有加大的帮助。
