| Abstract: | In parallel computing environment in a large-scale cluster system,I/O efficiency is always a key factor that affects the system’s overall performance.Parallel file system technology provides an effective way to solve I/O bottlenecks.The article describes the current status of the development of parallel file systems and parallel file system types,elaborates the architecture of SNFS parallel file system and load balance DLC(distributed LAN client)technology implementation principles,and presents an implement approach for SNFS file system load balance technology in large-scale cluster system environment.Finally,through application analysis the paper illustrates the advantage of the technology in improving I/O performance. |
