PC Scene Generation Bridge Architectures for Streaming Balanced Computation.

The proposed study will examine near-term bridging and switch fabric technology trends as a basis for a Personal Computer ("PC") based cluster architecture. The objective is to bring multiple Central Processing Units ("CPU") and Graphics Processing Units ("GPU") to bear on appropriate classes of existing and near-term Missile Defense Agency ("MDA") computational problems, such as physics-based sensor/guidance system simulations, missile plume atmospheric and radiometric phenomenology, and hardware-in-the-loop guidance development. We propose to perform case studies on MDA-related algorithms in conjunction with alternative candidate interconnection and CPU/GPU computational architectures. This approach is designed to identify an early practical application which will demonstrate the potential of switch fabric architectures with GPU processing. In the Phase I option, we propose to demonstrate a switch fabric architecture in which solutions to MDA problems can be prototyped.
