Cedar File System (CFS)

Xerox PARC, USA David K. Gillford, Roger M. Needham, J. Donahue and Michael D. Schroeder

Short Description:
The Cedar File System is a part of the Cedar Parallel Programming System. It is a workstation file system that provides access to both a workstation's local disk and to remote file servers via a single hierarchical name space. Cedar is designed to support group programming in the context of a collection of personal workstations, each with a local disk. Workstations are connected to shared file servers by a local area network, and all shared information is kept at the file server computers. CFS differs fro m previous distributed file systems by changing the semantics of the traditional interface to reflect the intended use.
