High End Computing (HEC) R&D advances fundamentally new approaches in high-capability computing, including the operation and utilization of systems and applications. These investments are reported in separate program component areas: Enabling R&D in High-Capability Computing Systems (EHCS), and High-Capability Computing Infrastructure and Applications (HCIA).

 

Overview

The HEC Interagency Working Group (IWG) was created in 1991 and currently coordinates Federal HEC R&D across 14 participating agencies and supports activities that extend U.S. leadership in high-capability computing (HCC). Guided by Pioneering the Future Advanced Computing Ecosystem: A Strategic Plan, the IWG focuses on the development of technologies that anticipate future needs, overcome current challenges, and ensure the effective use of HCC systems to support the Nation’s economic competitiveness, security, and leadership in science and engineering. EHCS investments drive innovation in areas such as precision medicine, smart and connected communities, and the next wave of autonomous machines.

The HEC IWG also coordinates the operation and modernization of HCC infrastructure and applications to accelerate scientific discoveries and technological innovations. HCIA investments provide researchers from academia, government, and industry tens of billions of computing hours annually on the Nation’s most powerful computing platforms and provide the ecosystem and expertise the United States needs in areas such as materials discovery and design, earth and space science, detection and treatment of diseases, and other applications of national interest.

Strategic Priorities in Enabling R&D in HCC Systems

  • Deliver innovative and capable HCC systems through novel computing and analytics approaches and technologies, and applications that fully exploit HCC capabilities.
  • Pioneer digital and nondigital frontiers “beyond Moore’s Law” including the advancement of quantum, neuromorphic, and probabilistic computing.
  • Boost productivity, programmability, portability, and usability of HCC systems through development of new architectural benchmarks and common tools for computational modeling, simulation, and data analysis.
  • Extend the breadth and impact of HCC through investigating new uses in and across domains such as weather forecast data assimilation or fusing data from hundreds of video feeds.
  • Ensure the future HEC workforce through improved education and increased training, re-training, and fellowship opportunities at all career levels.

Strategic Priorities in HCC Infrastructure and Applications

  • Acquire, operate, and provide to researchers HCC systems with the capability to meet critical national needs and support research and education in all areas of science and engineering.
  • Develop algorithms and applications software to support, maintain and improve the performance of applications, infrastructure, and the overall HCC ecosystem.
  • Continue to enhance the HCC ecosystem and infrastructure capabilities for computational and data-enabled science, modeling, simulation, and analysis.
  • Provide diverse user communities with efficient, effective, and dependable access to HCC and support collaborations to increase productivity and impact.
