[] MOS: A Multicomputer UNIX Distributed System Amnon Barak Department of Computer Science The Hebrew University of Jerusalem This talk describes the goals and the architecture of MOS, a general-purpose time-sharing distributed system which makes a set of independent computers behave like a single UNIX system. The main goals of the system are network transparency, decentralized control, load balancing and concurrency through dynamic process migration. The architecture is characterized by modularity, high degree of information hiding and hierarchical organization. We describe the load balancing policy which consists of three algorithms: The local load, used by each node to monitor its own load; the information exchange algorithm, for exchanging load information between the nodes, and the process migration algorithm which dynamically migrates processes, at any stage of the execution. The load balancing policy creates an environment which encourages concurrent processing. Some performance results of this policy will be given.
