| 摘 要： | 针对三维冲击问题,基于分块数据结构在共享内存并行机上实现OpenMP并行计算.分块数据结构不仅能有效利用计算机多层存储结构,而且增加OpenMP的并行粒度.数值实验表明:在使用分块数据结构后,串行程序的计算速度能提高3倍.通过柱体冲击平板数值模拟实验讨论并行程序的加速比和效率,表明并行程序能有效减少总计算时间.

| Abstract: | As to 3D impact problem,OpenMP parallel computation is implemented in shared memory parallel computer based on block data structure.Block data structure is not only effective use of computer multi-storage structure,but also improves the OpenMP parallel granularity.The numerical experiment indicates that the serial program with block data structure is three times faster than original version.The speedup and efficiency of parallel program are discussed by a numerical simulation on impact of cylinder into a plate and the result shows that the parallel program can decrease the total computation time effectively. |
