DSMC交互式并行化系统性能预测模型

Performance Forecast Model of DSMC Interactive-parallelizable System

对机群环境下的DSMC并行计算问题考虑了初始数据划分、系统负载平衡和网络通信情况等因素,建立了DSMC交互式并行化系统中的性能预测模型,分析了机群系统的物理参数如何影响DSMC并行模拟计算的效率。对两个实际DSMC问题的研究结果表明,性能预测结果与实际测试结果基本吻合,说明该方法是正确有效的。

The paper concerns such factors as initial data partition, system load balance and network communication, etc. in DSMC parallel computing problem under the condition of distributed computers, sets up a performance forecast model for DSMC interactive-parallelizable system and analyzes how the physical parameters of the distributed computers affect the efficiency of DSMC parallel simulation computation. The results of the study of two actual DSMC problems indicate that the DSMC parallel performance forecast model in this paper are practical and effective to the DSMC problems.
