求最长公共子序列的并行算法

Parallel Algorithm for Longest Common Subsequence in a String

Tirtharaj Dash, Tanistha Nayak

摘要:

在模式识别和匹配领域中,寻找最长公共子序列是一个非常重要的问题。本文提出了一种基于并行计算的算法。我们使用OpenMPAPI包作为中间件将数据发送到不同的处理器。我们已经测试了我们的算法在一个系统中有四个处理器和2 GB的物理内存。最好的结果表明,并行算法的性能(计算速度)提高了3.22。

英文摘要:

In the area of Pattern Recognition and Matching, finding a Longest Common Subsequence plays an important role. In this paper, we have proposed one algorithm based on parallel computation. We have used OpenMP API package as middleware to send the data to different processors. We have tested our algorithm in a system having four processors and 2 GB physical memory. The best result showed that the parallel algorithm increases the performance (speed of computation) by 3.22.
