Parallel Virtual File System, Version 2 Parallel I/O continues to be a topic of active development. Recent years have seen the creation of many new options. Even with these new choices, certain factors remain constant. Parallel applications need a fast I/O subsystem. Clusters need a parallel file system that can scale as the number of nodes increases to the thousands and tens of thousands. PVFS2 is our answer. Many institutions and researchers have used the first generation of the Parallel Virtual File System (PVFS) with much success. The time has come for the second generation. PVFS2 continues to serve as both a platform for parallel I/O research as well as a production file system for the cluster computing community. in Public bookmarkswith parallelcontinuestopicactivedevelopmentrecentyearscreation
