### Project DS7 — High Performance Computing Modernization Program

The High Performance Computing Modernization Program (HPCMP) addresses the supercomputing requirements of Department of War (DoW) scientists and engineers by (1) demonstrating and maturing the most advanced, leading-edge computational architectures and exploiting the resulting systems by employing complementary specialized expertise; (2) demonstrating and maturing the Defense Research and Engineering Network (DREN) which investigates, demonstrates, and matures leading-edge digital networking and security technologies to securely deliver computational capabilities to the distributed DoW Research, Development, Test, and Evaluation (RDTE) and acquisition engineering communities; and (3) leveraging specialized expertise from DoW, other federal departments/agencies, industry, and academia to demonstrate and mature leading-edge software application codes. DoW Supercomputing Resource Centers (DSRCs) provide extensive computational capabilities and demonstrate and mature emerging technologies that address the supercomputing requirements of the DoW RDTE and acquisition engineering communities in the areas of hardware, software, and programming environments. HPCMP sites are interconnected to each other, the DoW High Performance Computing (HPC) RDTE community, and other major defense sites via DREN, a research network which investigates, demonstrates, and matures (a) state-of-the-art digital networking technologies to ensure a robust distributed environment and (b) the most advanced digital security capabilities to effectively protect the intellectual property of the DoW and its contract entities as they employ HPCMP advanced capabilities. The HPCMP's software application effort (a) optimizes, enhances, demonstrates, and matures critical DoW physics-based and engineering software to allow scientists and engineers to execute calculations with precision and efficiency on leading-edge supercomputers, (b) demonstrates and matures immersive collaborative programming environments to improve science and engineering workflows, and (c) demonstrates and matures leading-edge computational technology from academia and industry.

| Activity (R-2A) | FY2025 | FY2026 | FY2027 |
|---|---|---|---|
| Department of War Supercomputing Resource Centers | 136.9 | 132.5 | 125.0 |
| Defense Research and Engineering Network (DREN) | 54.4 | 51.0 | 46.2 |
| Software Applications | 39.9 | 53.1 | 43.9 |

> R-2A activities carry the prior, current and budget year only — no five-year plan. Coverage is partial, so count them, never total them.

## Mission & acquisition strategy

The High Performance Computing Modernization Program (HPCMP) addresses the supercomputing requirements of DoW scientists and engineers by: (1) demonstrating and maturing the most advanced, leading-edge computational architectures while exploiting the resulting systems by employing complementary specialized expertise; (2) demonstrating and maturing the Defense Research and Engineering Network (DREN), which investigates, demonstrates, and matures leading-edge digital networking and security technologies to securely deliver computational capabilities to the distributed DoW RDT& community; and (3) leveraging specialized expertise from DoW, other federal departments and agencies, industry, and…
