一个基于NOW的跨平台并行文件系统的设计和实现

The Design and Implementation of a Parallel File System Based on The Heterogeneous Network of Workstation

1.引言近年来,国内外对并行文件系统做了很多的研究,著名的有:一些商用的并行文件系统,如Intel为iPSC/2和iPSC/860而设计的CFS,以及IntelParagon的并行文件系统PPFS。还有HPF的运行支撑系统PASSION。研究性的则有PIOUS等。它们通常是针对并行机设计的,应用范围较为狭窄。随着对NOW(Network of Workstations,工作站网络)的研究深入。

To improve the I/O performance of a parallel system,we designed and implemented a Parallel File System Based On The Heterogeneous Network Of Workstation(PFSHNOW). It is a cross-platform parallel file system , and has some characteristics such as parallelism, efficiency , cross-platform, convenience of management,and intelligence. This article described the model of the PFSHNOW and the advanced technique used in the file system. At the end ,we also gave the result of evaluation.
