Abstract

PM is a new object-oriented methodology which allows a more structured approach to the specification and implementation of software for distributed and multiprocessor architectures. In order to evaluate the correctness and efficiency of the PM prototype implementation, it has been decided to build a highly parallel distributed file system as a first application.This paper outlines the design of this file system. Starting with the proposal of an overall structure for the system, we will then detail each type of object it will be made of and propose solutions in response to the classical problems encountered in the area of file systems, provision of a transaction mechanism and guarantee of the consistency of the users' data.
