“…As these all required significant additional compute power, software systems stressing efficient inter-node communications were necessary to achieve desired scalability . These developments rested on the work that was led by Paul Messina at Caltech (Messina et al 1997). The Synthetic Forces Express project (SF Express) began to explore the utility of SPPs as a solution to the communications bottlenecks that were then being experienced.…”

“…More than 100,000 vehicles were simulated in 1998, using several different types of SPPs at nine separate sites, linked by a variety of widearea networks. (Brunett 1997) This type of simulation frequently has a map visualization, as shown in Figure 2. The menu on the left allows the operator to lay down entities on the map, give them direction, modify their behaviors, and adjust their movements.…”

This paper presents the case that education in the 21 st Century can only measure up to national needs if technologies developed in the simulation community, further enhanced by the power of high performance computing, are harnessed to supplant traditional didactic instruction. The authors cite their professional experiences in simulation, high performance computing and pedagogical studies to support their thesis that this implementation is not only required, it is feasible, supportable and affordable. Surveying and reporting on work in computer-aided education, this paper will discuss the pedagogical imperatives for group learning, risk management and "hero teacher" surrogates, all being optimally delivered with entity level simulations of varying types. Further, experience and research is adduced to support the thesis that effective implementation of this level of simulation is enabled only by, and is largely dependent upon, high performance computing, especially by the ready utility and acceptable costs of Linux clusters.

“…These sites were linked by a variety of wide-area networks. (Brunett, 1997) This work depended on the existing DIS standard utilized by the SAFs at that time. That standard was replaced by the HLA/RTI standard that was purportedly more scalable, but several years of use has shown the clear limits of this simulation approach.…”

DISTRIBUTION CODE ABSTRACT (Maximum 200 Words)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 "fought" from Suffolk, VA.

The cover illustration shows an unstructured symmetry plane surf ace grid and tetrahedral fie1d cut for a NASA Space Shuttle Orbiter configuration. The complete volume grid contains 547,741 nodes and 3,026,562 tetrahedral elements and was used for an inviscid CFD analysis. The geometry preparation and grid generation work were performed by David L. Marcum and J. Adam Gainther using SolidMesh with AFLR volume and surf ace generators at the MSU/NSF Engineering Research Center for Computational Field Simulation at Mississippi State University.
