面向水下声场计算的PC集群构建

水下声场计算复杂,计算量大,目前的模型难以满足在水下战场环境仿真中对声场的实时性的要求.计算机技术的发展,特别是高性能集群的出现,为解决此问题提供了一种可行的方法.文中首先介绍了如何将单PC机通过以太网连接起来,构建实验环境下的用于水下声场计算的PC集群,然后给出了在此系统上运行水平不变声道中WKBZ简正波并行计算方法及FOR3D模型的并行方法的结果.实验结果表明,此系统能够可以为水下声场计算提供一个很好的并行环境,集群系统在水下声场及其相关领域必将有很大的应用空间.

Constrction of PC Cluster Based on Linux

The computation of underwater acoustic field is complicated,and always costs a lot of time.The present model of acoustics is hard to meet the requirement of the real time computation of acoustic filed in battlefield environment simulation.The development of computer technology,especially the development of high performance cluster provide a feasible method to solve this problem.This papaer introduces how to connect the single PC to PC cluster,by using Ethernet for computing acoustic field,and gives out the test result by using parallel programme of WKBZ mode and FOR3D model.The experiment result indicates that this system can provide a very good parallel environment for the computation of underwater acoustic filed.The PC cluster will have a large application space in computation of underwater acoustic field.
