WKBZ简正波方法的并行实现

The Parallel Programme of WKBZ Mode Approach

声波是人们探测海洋的重要手段,快速准确预报声波在海洋中的传播对人们进一步认识海洋有重大意义。并行算法是解决大数据量运算耗时过久的重要途径,在PC机群上实现并行算法是一种低成本、高效率的解决方案。文章介绍了如何在机群系统上实现WKBZ简正波方法的并行化,对并行算法进行了测试,比较了并行WK-BZ简正波计算和传统WKBZ简正波计算耗时的差异。最后,根据理论研究和实际测试的结果,总结了利用PC机群系统进行并行WKBZ运算的可行性,得出了一些有意义的结论。

Sound wave is an important mean to explore the ocean. It is very important for us to predict the transmission of underwater acoustics o Parallel programming is the important method to enhance the speed of multiple data operation and in the low-cost, high efficiency project proceeded in a cluster of PCs.This paper firstly introduced the basic therapy of parallel algorithms, and then discussed the cluster of PCs system and MPI o Secondly, this paper realized the parallel algorithm of the WKBZ mode approach .The time differences between Parallel WKBZ and traditional one were analysed after this programwas tested. Finally,from tlhe theoretical and practical study, the feasibility of proceeding parallel WKBZ in cluster of PCs was discussed and some meaningful conclusions were also achieved.
