摘　　要：Beowulf集群系统是基于广泛应用于通用网络环境下由一些微机组成的计算机群系统,它可以运行于多种操作系统(如Linux、Windows等)。主要研究了在WindowsXP操作系统下异构Beowulf集群系统的构建,利用计算圆周率的并行算例进行了系统性能测试,并与Sun高性能服务器测试结果进行了比较。测试结果表明实验构建的Beo-wulf集群具有很高的并行计算效率和并行加速比,能够达到比较好的实际效果。The Beowulf cluster system is a collection of personal computers interconnected by widely available networking technology running any one of several operating systems as Linux or Windows. The construction of the heterogeneous Beowulf cluster system under Windows XP is researched. With the parallel example of PI this Beowulf system is tested,and the results are compared with Sun high-performance servers. Results show that the Beowulf cluster system could run high parallel computing efficiency and parallel speedup, and get a better effect.
