摘要
为了测试KOKLE PC-C luster008-01微机群并行计算机的并行处理性能,开发了基于M P I函数库的并行处理性能基准测试软件KOKLEBT。该软件使用SOR方法来求解大规模定常热传导工程问题。为了进行并行处理,对数值分析问题进行了纵向和横向域分解,并分配给参与并行计算的微机群,达到了预期的测试目的。
In order to test the parallel computational performance of KOKLE PC-Cluster008-01, this paper set up the testing software,KOKLEBT,based on the MPI function bank. The software was used to solve big engineering problems of heat exchange via SOR. The paper carried out parallel computations by means of horizontal and vertical domain decomposition of numerical analysis and allocating them to every clusters. The results proved that the anticipative aims such as speed-up, efficiency, computational dimensions and calculation-time were attained.
