Breaking the constraints to a high performance metacomputing system : a system approach

The Theory of Constraints (TOC) maintains that every system has its goal. There are necessary conditions that must be satisfied in order to achieve the goal. A constraint is a condition that prevents a system from satisfying a necessary condition or reaching the goal. This paper, by using a system approach, starts by identifying users' requirements, presents a discussion on system goal and necessary conditions for a metacomputing system on the Internet. Constraints that prevent a system from achieving applicability, efficiency, scalability and reliability are particularly exploited. Corresponding injections to break and/or balance the constraints are presented.
