摘　　要：作为曙光 30 0 0超级服务器的重要组成部分 ,COSMOS机群文件系统对机群文件系统协议、结构及性能优化等问题进行全面深入的探讨 .首先描述了基于曙光 30 0 0机群高速通信协议 BCL - 3的 COSMOS文件系统的实现 ,然后引入并发带宽利用率 ,描述了通信与 I/ O对机群文件系统性能影响程度 ;As an important component of Dawning 3000 super server, the COSMOS cluster file system allows to explore many important fields in the cluster file system, including architecture, protocol and performance optimization. Described in this paper is the implementation of the COSMOS cluster file system based on BCL 3 high speed communication protocol in Dawning 3000 cluster. Then parallel bandwidth utilization is introduced to describe the influence of communication and I/O subsystem on the performance of the cluster file system. Finally, the related experiments are reported and explained.
