This session presents some of the challenges facing the military simulation and training community as we extend the operational life of existing simulators thru technology insertion and modernization. Solutions to these challenges involve embracing the application of virtualization to existing system architectures, and extending into cloud based services as part of future architectures. We specifically look at unique requirements for real-time 3D image generation and explore approaches to using NVIDA virtual GPU technologies to provide the required performance while capitalizing on the reduced footprint and enhanced sustainability afforded by virtualize GPUs.
