Abstract
An adaptive Dual-Cache Scheme(DCS) and dynamic prefetching scheme were designed to improve the performance of the Parallel File System for Linux(PFSL). PFSL is a parallel file system for a clustering environment and is implemented using a multi-threaded programming technique with POSIX thread libraries supported by Linux. The proposed adaptive DCS and dynamic prefetching scheme both reflect the current file request. The former reduces the first file request response time, whereas the latter improves the file system performance by adjusting the amount of data for prefetching.
