摘要
从解决高性能计算机I/O瓶颈面临的问题着手,首先详细分析并设计了并行网络文件系统——PNFS的结构、存储机制、管理机制和工作机制,然后对并行网络文件系统PNFS的原型系统进行了性能测试,从而验证了并行网络文件系统PNFS可以有效地解决传统网络文件系统在可扩展性、可用性和性能上存在的问题,能够为高性能文件系统的建立提供一种行之有效的解决方法。
Beginning with the problems of solving the I/O bottleneck of high performance computer. First, this paper mainly analyzed and designed the architecture, access mechanism, management mechanism and operating mechanism of parallel network file system-PNFS. Second, we made the test of PNFS, and the results show that PNFS can resolve the problems of traditional file systems about scalability, availability and performance and provides an effective method for building high performance file system.
