    (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)


High End Computing (HEC) is a vital technology enabler for the U.S. government, academia, and industry, which enables and accelerates scientific discovery and product development, advances economic competitiveness and innovation, and helps to ensure national security.

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.

HEC agencies coordinate Federal activities to provide large-scale, shared information technology infrastructure and applications that supports or enables high-capability computing R&D, including computation- and data-intensive systems and applications, and associated software, communications, storage, and data management infrastructure to meet Federal agency mission needs and support national competitiveness.

HEC also focuses on advancing the field of high-capability computing (HCS) through HCS R&D. This includes R&D in HCS hardware and its subcomponents, systems and application software, architecture, algorithms, and software development methods for extreme data- and compute-intensive workloads; and developing fundamentally new approaches to high-capability computing. HCS includes fundamental research, applied R&D, technology development and engineering, infrastructure and applications, demonstrations, testing and evaluation, technology transfer, and education and training. This includes supporting national initiatives and coordinating programs, budgets, and policy recommendations and facilitating information sharing among agencies for HCS R&D.

Example research areas of interest include hardware (e.g., microarchitecture, memory subsystems, interconnect, packaging, I/O, and storage), software (e.g., operating systems, languages and compilers, development environments, algorithms), and systems technology (e.g., system architecture, programming models).

    Session Leader(s) Darren L. Smith, Frederica Darema
    Abstract: In this BOF, representatives from several U.S. federal funding agencies will overview their programs and initiatives related to HPC. DoD, DOE, NASA, NIH, and NSF will briefly present opportunities spanning the areas of applications modeling and algorithms, big-data-enabled applications, programming environments and software tools, systems software, operations support, instrumentation systems, and cyber-infrastructures. The second half of the BOF will be dedicated to questions from the audience. The BOF provides a forum for the broader research community to learn about U.S. federal R&D funding opportunities in HPC and discuss program directions for new research and technology development and supporting infrastructures.

    Supercomputing (SC) 15 Panel

    Event: Supercomputing (SC) 15 Panel- Supercomputing and Big Data: From Collision to Convergence - Austin, Texas, 11/18/2015
    Panelists Peter Lyster, David Bader, Ian Foster, Bruce Hendrickson, Randy Bryant, George Biros, Andrew W. Moore
    Website: http://sc15.supercomputing.org/
    Abstract: As data intensive science emerges, the need for high performance computing (HPC) to converge capacity and capabilities with Big Data becomes more apparent and urgent. Capacity requirements have stemmed from science data processing and the creation of large scale data products (e.g., earth observations, Large Hadron Collider, square-kilometer array antenna) and simulation model output (e.g., flight mission plans, weather and climate models). Capacity growth is further amplified by the need for more rapidly ingesting, analyzing, and visualizing voluminous data to improve understanding of known physical processes, discover new phenomena, and compare results.
    • How does HPC need to change in order to meet these Big Data needs?
    • What can HPC and Big Data communities learn from each other?
    • What impact will this have on conventional workflows, architectures, and tools?
    An invited international panel of experts will examine these disruptive technologies and consider their long-term impacts and research directions.
