A distributed, parallel implementation of the widely used Modular Semi-Automated Forces (ModSAF) Distributed Interactive Simulation (DIS) is presented, using networked high-performance resources to simulate large-scale entity-level exercises. Processing, communication and I/O demands increase dramatically as the simulation grows in terms of size or complexity. A general framework for functional decomposition and scalable communications architecture is presented. An analysis of the communications load within a single computer and between computers is presented. Ongoing activities to address more dynamically communication limitations and processing load using Globus are discussed.
