GVFS (originally named PVFS) is a virtualized distributed file system for providing high-performance data access in grid environments and seamless integration with unmodified applications. It leverages existing NFS (Network File System) support in operating systems, and uses user-level proxies to authenticate and forward RPC (Remote Procedure Call) requests between the native NFS client and server, and map user identities between different domains. GVFS helps users to access Grid data the same way as using NFS in LAN. It is also an important component of In-VIGO virtualization middleware for computational Grids. |
