高性能服务器上爆轰波传播的并行计算

Parallel Computing of Detonation Wave Propagation on High Performance Server

在基于CC-NUMA结构的高性能计算机上,研究三维空间非理想爆轰波传播的并行化计算。通过对原串行程序进行分析与测试,确定了以曲率计算、第一次差分计算和第二次差分计算等为并行化的重点。结合并行机结构特点,采用“分而治之”和负载平衡等并行处理技术,将串行程序转化成并行程序。在高性能服务器上进行数值模拟计算与测试表明,爆轰波传播并行程序的运算速度得到了大幅度的提高。

The parallel computing of non-ideal 3-D space detonation wave propagation on HPC with CC-NUMA structure is introduced. Through the analysis and test of original serial program system, curvature computing and first difference, second difference etc. are defined as key objects. Using 揇ivide and Conquer? loaded balance and many other parallel processing techniques, serial program is transformed to parallel program. The numerical simulation and test on high performance server show that the operation speed of detonation wave propagation parallel program is enhanced greatly.
