Abstract: This paper is intended to serve as an introduction to two other papers: User-Directed Control of Parallelism: The CAGE System; and Poligon: A System for Parallel Problem Solving, two different skeletal systems, representing two models of concurrent problem solving, are described in those reports. Both systems are designed for parallel execution of application programs built with the systems. This paper describes the context in which these systems are being developed and summarizes the differences between the two systems.
