构建面向对象的并行有限元计算集群

Building PC cluster for parallel FE analysis by object oriented method

介绍了一种面向对象的方法来组建计算机集群进行并行有限元分析。将构成集群系统的软、硬件组件设计成不同的类层次结构,形成一个完整的集群系统类库,并以系统分析、总体设计、结点通信以及系统效率测试等过程尝试以系统化的方法来分析整个构建过程。实际结果及并行有限元分析算例表明,这样的设计策略,可以非常清晰地从整体上把握系统的实现,大大降低系统构建的复杂性,使所生成的系统具有很好的可扩展性。

This paper represents an object oriented method to build the PC cluster to perform parallel finite element analysis. This method is to design all the components installed in cluster, including all software and hardware, into some kinds of classes, and use these classes to show the connectivity between different parts in a cluster, a complete class hierarchy map will be formed in the end. By this way, a systematic method can be made to analyze the whole building process which includes system analysis, whole structure design, communication between computing nodes and system tests. Examples show that this kind of method can make full use of kinds of advanced parallel and distributed computing tools nowadays, decrease the complexity to build a cluster for parallel FEA, and serve as a good base for the future grid computing.
