Abstract : The Joint Experimentation on Scalable Parallel Processors (JESPP) project exemplified the accessibility and the utility of High Performance Computing for large-scale simulations. In order to simulate the future battlespace, the US Joint Forces Command's (USJFCOM) Experimentation Directorate (J9) required expansion of its joint semi-automated forces (JSAF) code capabilities; including number of entities, behavior complexity, terrain resolution, infrastructure features, environmental realism, and analytical potential. The USJFCOM J9 was charged with developing a very large-scale simulation capability of future combat environments, particularly urban areas, with more than one million civilian simulated entities. Synthetic forces have long run in parallel on networked computers. The JESPP strategy exploited the scalable parallel processors (SPPs) of the High Performance Computing Modernization Program (HPCMP). SPPs provide a large number of processors, interconnected with a high performance switch and a collective job management framework. To achieve the goal of simulating one million entities, software routers were developed that replaced multicast with point-to-point transmission of interest-managed packets. This final report lays out that design and development. It also details several experimentation events that have simulated up to one million clutter entities, which were "Thought" from Suffolk, VA.
