  • High End Computing
    (HEC IWG)

    The HEC IWG coordinates the activities of the Enabling R&D for High-Capability Computing Systems (EHCS) and High-capability Computing Systems Infrastructure and Applications (HCSIA) Program Component Areas.



High End Computing (HEC)
Interagency Working Group (IWG)


The HEC IWG focuses on R&D for advancing high-capability computing and revolutionary computing paradigms, as well as providing the Nation with state of the art compute, communication, software, and associated infrastructure.

HEC R&D (known as EHCS) includes R&D of increasingly capable computing technologies and emerging computing technologies, such as quantum computing, neuromorphic computing, and other novel computing technologies, as well as support for hardening of research software. These have the potential to lay the foundation to extend U.S. global computing leadership, spur technological innovations, and create new economic opportunities. HEC R&D includes, but is not limited to, R&D of hardware (e.g., microarchitecture, memory subsystems, interconnect, packaging, I/O, and storage), software (e.g., operating systems, languages and compilers, development environment, algorithms), and system technology (e.g., system architecture, programming models) for high capability compute-intensive and data-intensive computing. HEC R&D includes fundamental research, applied R&D, technology development and demonstration, test and evaluation, technology transfer, and development of future workforce who will advance the field of HEC.

HEC also focuses on providing computation- and data-intensive high-capability computing infrastructure and application (HCIA) to support agency mission needs and diverse initiatives that advance U.S. priorities. HCIA includes computation- and data-intensive systems and applications, associated software, communications, storage, and data management infrastructure, and other resources needed to enable agencies and the wider HEC community to fully utilize and exploit the capabilities of these infrastructure.

HEC IWG coordinates programs, budgets, and policy recommendations and facilitates information sharing among agencies for EHCS and HCIA.
