An efficient parallel sorting algorithm,which is implemented on a shared memory multiprocessor system,is presented.The sequence that has n elements to be sorted are partitioned to p subsequences(length n/p ).First the p subsequences are sorted in parallel by 2 hashing,its average time is O( n/p ).Then the p sorted subsequences are merged in parallel to a sorted sequence(length n ),its time is O( n-n/p ).The total parallel execution cost is O( np ).This scheme can be extended to the...

本文提出一个在共享存储多处理机系统上实现的快速、有效的并行排序算法:将长度为n的待排序数据划分成p个长度为n/p的子序列,引入散列技术并行地对这p个子序列的数据进行二次散列排序,这一阶段所需的平均时间为O(n/p);最后并行地将p个有序子序列归并成一个长度为n的有序序列,归并阶段所需的时间为O(n-n/p)。整个排序算法的并行执行代价为O(np)。本排序方法可以拓广到网络并行机群环境。

Largescale numerical analysis of pollutant distributions in the Three Gorges Project requires a parallel processing algorithm to simulate shallow water flow. A parallel algorithm was developed using domain decomposition and a reordering algorithm. The parallel solution of the shallow water equations was verified by analyzing the flow around a circular cylinder at low Reynolds number (Re≤300) in shallow water. The results, including the values of Strouhal number and the circulation zone length, agreed well with previous results. The calculating program and its corresponding parallel algorithm are numerically stable, precise and quickly convergent. The algorithm can be used to simulate flow in rivers.

针对大规模水环境预测的需要,建立了网络并行机群系统(COW),进行浅水流动的并行计算研究。并行计算实现过程中引进了一种基于图论的区域分解算法,同时提出了一种针对并行计算的网格重新编号算法。作为浅水流动并行程序的验证,计算了较低Reynolds数情况下(Re≤300)圆柱绕流的流态,将各种特征物理量如Strouhal数、回流区长度等与前人的结果进行了比较。计算结果表明:浅水流动计算程序及相应的并行算法具有计算效率高、收敛速度快以及计算精度高等优点,可进一步应用于天然河道流场的并行模拟。
