摘　　要：机群是当前高性能计算领域的主流体系结构,随着Linux操作系统的成熟和pc机性能的提高,用Linux和pc节点构造的机群系统越来越多地应用于高性能计算领域。I/O子系统和机群文件系统的性能对整个机群系统的性能有重要的影响,本文在曙光3000cosmos犤6,10犦机群文件系统的基础上,针对曙光3000LLinux机群系统设计实现了基于Linux的机群文件系统cosmos-L,对cosmos-L进行了性能测试,并与PVFS文件系统进行了比较。Cluster systems are popular architectures in the area of high performance computing. With the development of Linux and improvement of pcs perfomance,it is more and more popular that cluster systems made up with pc nodes areapplied in high performance computing. The performance of I/O subsystem and cluster filesystem is important to the performance of the whole system. We implement a Linux cluster filesystem based on the Darwing3000 cluster filesystem,which is called cosmos-L. We compared the performance of cosmos-L and PVFS.
