Parallel programme of WKBZ mode approach to sound propagation in horizontally stratified oceans

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。首先介绍了计算机机群系统,在此基础上,建立了基于LINUX和MPI的PC机群实验环境,实现了WKBZ简正波方法并行计算,并利用建立的试验平台,对并行算法进行了测试,比较了并行WKBZ简正波计算和串行WKBZ简正波计算耗时的差异。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。

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, According to this theory,an appropriate laboratory environment, a simple cluster of PCs based on LINUX and MPI, was established. 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 programs tested, Finally,from the theoretical and practical study,the feasibility of proceeding parallel WKBZ in cluster of PCs was discussed and some meaningful conclusions were also achieved,
