中文摘要：

讨论了应用普通的PC机和Linux操怍系统以及其他免费软件实现的BESⅢ在线数据获取系统的测试计算机集群的设计与实现。系统运行正常．并且为在线软件提供了很好的反馈以及诊断，所采用的技术将被应用到实际的BESⅢ在线数据获取系统上。同时也可以应用到其他目的的集群系统上，如物理分析。

英文摘要：

The design and implementation of the BESⅢ online data acquisition system test farm with PC, Linux and other free software are presented. The system has been running smoothly and provided good feedback and diagnose for the online software. It will be ported to the real online system. The idea presented here can be applied to other purpose farm, such as a physics analysis farm, too.
