Can the United States Maintain Its Leadership in High-Performance Computing?


March 2022

Subcommittee to:

Maintain world-leading capabilities in key technologies

  • How can the Department maintain critical international cooperation in an increasingly competitive environment for both talent and resources? In areas where the U.S. is leading, how can we sustain our roles and attract the best industry and international partners? In other areas, how can the Department build and maintain its reputation as a “partner of choice”? In general, are there barriers that can hinder our ability to form effective and enduring international and industry partnerships?
  • Identify key areas where the U.S. currently has, or could aspire to, leadership roles in advanced computing and high-end computational science and engineering, including unique or world-leading capabilities (i.e., advanced scientific facilities, testbeds and networks) or leading scientific and technical resources, such as highly trained personnel and supporting infrastructure. This may include emerging areas or opportunities that offer significant promise for leadership.
  • To preserve and foster U.S. leadership roles within reasonable resource constraints, are there particular technical areas or capabilities that could be emphasized? Are there
    other technical resources and capabilities that could be leveraged in to achieve these goals, possibly through collaborations within and beyond the ASCR community?
  • How can programs and facilities be structured to attract and retain talented people? What are the barriers to successfully advancing careers of scientific and technical personnel in advanced computing, computational science and engineering, and related fields and how can the Department address those barriers? A complete answer to these questions should address how we can ensure that we are recruiting, training, mentoring, and retaining the best talent from all over the world, including among traditionally underrepresented groups within the U.S.
