The High Performance Computing Modernization Program (HPCMP) delivers world-class commercial, high-end, high-performance computational capabilities to the Department of Defense's (DoD’s) Research, Development, Test and Evaluation (RDT&E) and Acquisition Engineering (AE) communities through its five DoD Supercomputing Resource Centers (DSRCs).

The DSRCs provide DoD scientists and engineers with the resources necessary to solve the most demanding computational problems. Each Center is a robust collection of high-performance computing (HPC) capabilities, which include: large-scale HPC systems, high-speed networking, multi-petabyte archival mass storage systems, and customer support services. Complementing our DSRCs and providing additional services to the DoD HPC community are four Affiliated Resource Centers (ARCs), an HPC Help Desk, and a Data Analysis and Visualization (DAV) Center. Our Centers enable scientific productivity for HPCMP customers using a potent combination of synchronized resource, workload, and enterprise system management services.

Centers assist customers through collaboration, technology, and service support.

All five Centers were provided new supercomputing capabilities from Liqid and Penguin Computing during the latest supercomputer acquisition cycle. These supercomputers enable the DoD science and research communities to test and model defense systems that cannot be modeled in the real-world due to time, financial, physical, or safety constraints. In some cases, they can accomplish this work in a matter of hours as opposed to the days, weeks, or even months that traditional research methods can require.
