Abstract:
This paper presents a framework for distributed simulation that is based on system-theoretic and logical-process concepts. The framework describes a three part world-view for developing simulation models. These are modeling formalisms, abstract simulators, and computational environments. A unified view of time and causality allows for the application of system-theoretic notions of causality within a distributed simulation environment. Within this framework, we introduce a unified notion of causality. Further we describe an approach for developing distributed simulation models which evolve from modeling constructs to simulation algorithms and their implementations. The framework is exemplified using the Discrete EVent System Specification (DEVS) modeling formalism, its abstract simulator, and a parallel algorithm that implements the abstract simulator.
