The design of a file system for a multiprocessor interactive computer system is described. The architecture of the computer system is such that direct access to a resource allocated to a process is not allowed to any other process. Thus, sharing of files can only be done by transmission of copies. The file system is functionally distributed so that different functions run on different processors and some functions are implemented in firmware. Also, there are no global file directories. The construction of a one process file system that is extensible and very modular is detailed, and facilities for file sharing among processes are then presented.
