摘要
分析桥梁结构软件的应用情况,介绍桥梁仿真计算中采用串行计算方式与并行计算方式的区别。着重介绍应用MPICH重构桥梁结构分析软件,使串行的桥梁结构分析软件在计算单元及节点的活载效应时具有并行计算的功能,并介绍并行化计算中处理器任务的分配。最后简要介绍桥梁结构分析软件中常用到的MPI函数,以及并行化计算方法的实践应用情况。
This paper analyzes the application of the software for bridge structure analysis, makes a difference between the ways of serial calculation and parallel calculation applied to bridge structure simulation calculation and describes in detail the application of the MPICH to reconstruction of the software for bridge structures analysis in order to make the serial calculation software have the parallel calculation function when used for calculating live toad effect of a unit and node and also the job allocation in the processor for the parallel calculation. In addition, the paper briefs the MPI functions frequently used in the software and the practical application of the way of the parallel calculation.
