Gfarm v2: A Grid file system that supports high-performance distributed and parallel data computing

Grid Datafarm architecture is designed for facilitating reliable file sharing and high-performance distributed and parallel data computing in a Grid across administrative domains by providing a global virtual file system. Gfarm v2 is an attempt to implement a global virtual file system that supports a complete set of standard POSIX APIs, while still retaining the parallel and distributed data computing feature of Grid Datafarm architecture. This paper discusses the design and implementation of Gfarm v2 that provides a secure, robust, scalable and high-performance global virtual file system.
