基于多块结构网格的并行计算及负载平衡研究

从并行计算流体力学程序的稳定性和效率两大问题入手,针对多块结构网格的通用数据传输方法和基于遗传优化算法的负载平衡方法,并在已有串行多块结构网格程序基础上发展了相应的并行程序.该并行程序以物理区域分割为基础,采用MPI实现消息传递,适用于各种不同的并行机体系结构,具有很好的可移植性.大量数值实验证明,本文发展的并行程序具有良好的稳定性和并行效率,可以进一步应用于大规模实际工程计算.

Study on Parallel Computation and Load Balance Strategy Based on Multiblock Structured Grid

In order to improve stability and efficiency of computational fluid dynamics(CFD) program,a general data transfer method and a genetic algorithm load balance strategy-based,are presented in this paper,A parallel program is developed on the basis of existing serial program for the multiblock structured grid.This parallel program whose message transport mechanism is based on the MPI can be run on different parallel computer architectures and has better portability.Many numerical experiments show that the para...
