摘要
提出了基于网络机群的有限元并行分析方法,结合网络机群体系的特点,分析了这一方法所应具有的基本特点:分布式并行建模;子区域间计算任务弱相关;节点负载平衡。在自建的网络并行平台上,实现了无重叠区域分解直接算法的并行处理,并进行了算例验证。
In this paper, a parallel finite element method based on cluster system is proposed. According to the characteristics of cluster system, the basic properties of this method, distributed parallel modeling; weak relevancy of computing task between subdomains; equilibrium of node computing loading are presented. A 4-node cluster system is built and a parallel computing program is developed using non-overlap domain decomposition direct algorithm. The program is also verified by numerical example.
