摘要: 以配置有局部存储器和共享存储器的多处理机系统为应用的硬件环境,讨论文[1]中提出的EBE-PCG法的实现问题,特别讨论了与任务的配置、数据的存储与访问以及通讯同步有关的问题。最后利用该算法在神州2-240超并行计算机系统上实现了一个结构静力分析问题的计算。结果表明它能有效节省存储量且在并行计算时能有效提高运算速度,是一种有效的超大规模工程结构分析问题的求解方法。

Abstract: By using multiprocessor systems equiped with local memory and shared memory as the hardware enviroment of the application, the implementation of EBE-PCG method is discussed. with especal attention on the problems relating to configuration of tasks,storation and visiting of datas,communication and synchronization. Finally,a structural analysis problem is solved by use of EBE-PCG method.The results show that the algorithm is effective numerical method for the super-large scale structural analysis problems.

Key words: structural analysis, finite element method, parallel algorithm
