In this paper, we describe the analysis of the effect of vertical computational scaling on the performance of a simulation based training prototype currently under development by the U.S. Army Research Laboratory. The United States military is interested in facilitating Warfighter training by investigating large-scale realistic virtual operational environments. In order to support expanded training at higher echelons, virtual world simulators need to scale to support more simultaneous client connections, more intelligent agents, and more physics interactions. This work provides an in-depth analysis of a virtual world simulator under different hardware profiles to determine the effect of increased vertical computational scaling.
