Describes a computer operating system boss-slave relationship between processes, different from the normal relationship between processes, which is useful for a number of purposes. These purposes include debugging of programs, analysis of process behavior, control of a process to enhance security, and extension of the capability of the operating system supervisor for a variety of purposes, including simulation of other operating systems. Varieties of this mechanism have been successfully implemented in several operating systems, and have proved quite valuable. This paper discusses the important aspects of the implementation of the boss-slave relation, and the uses to which it can be put. 13 pp. Ref.
