DescriptionThe US Department of Defense High Performance Computing Program (DoD HPCMP) provides the DoD computational science and engineering community three key elements of an HPC ecosystem: 1) five computer centers with a total computing capacity of 31 PetaFLOPS, 2) DREN, a high-bandwidth, low-latency network to connect the customers with the computers, and 3) application software support. The exponential growth in computing power over the last 60 years now gives DoD engineers the ability to accurately predict the performance of full-scale weapon systems (e.g., a full-size ship or airplane). To realize this capability, the CREATE program was launched in 2007 to develop and deploy eleven physics-based HPC engineering tools for the design and analysis of ships (e.g. aircraft carriers, destroyers,..), air vehicles (fighters, bombers, submarine surveillance airplanes,...), ground vehicles (trucks, personnel carriers, tanks,...), and radio frequency radars and antennas, together with the ability to generate the meshes and geometries needed for analysis. These tools enable engineers to develop virtual prototypes of weapon systems. By analysis of those prototypes with high-fidelity, physics-based tools, design defects and performance shortfalls can be identified and fixed before metal has been cut. This reduces rework and the risks, costs, and time of acquiring and maintaining major DoD weapon systems. The tools are being used by more than 160 DoD engineering organizations (government, industry, and academia) and approximately 1,400 users. Illustrative examples of these applications and their impacts will be described during the presentation.
