CFD显式差分程序的自动并行技术研究

Research on Automatic Parallelization of Explicit Difference Programs of CFD

对显式计算程序的自动并行技术作了研究和探讨。从应用的角度出发,充分利用显式差分的特点和模拟手工并行的过程,集中CFD研究了区域划分、相关性分析以及同步通信与优化等自动并行的核心技术。

The thesis studies the parallelization of explicit difference programs of CFD (computational fluid dynamics) on the distributed systems. Taking full advantage of characteristics of explicit difference and simulating the process of artificial parallelization , the research is focused mainly on domain partition, dependency analysis and the optimization of related synchronization communication which are all kernel techniques of automatic parallelization . Keys wordsAutomatic parallelization; Computational fluid dynamics(CFD); Explicit difference; Eependency analysis; Optimization of communication
