Computational Science Charter
  • How well is the Federal government targeting the
    right research areas to support and enhance the
    value of computational science? Are agencies
    current priorities appropriate?
  • How well is current Federal funding for
    computational science appropriately balanced
    between short term, low risk research and longer
    term, higher risk research? Within these research
    arenas, which areas have the greatest promise of
    contributing to breakthroughs in scientific
    research and inquiry?
  • How well is current Federal funding balanced
    between fundamental advances in the underlying
    techniques of computational science versus the
    application of computational science to
    scientific and engineering domains? Which areas
    have the greatest promise of contributing to
    breakthroughs in scientific research and inquiry?

Computational Science Charter
  • How well are computational science training and
    research integrated with the scientific
    disciplines that are heavily dependent upon them
    to enhance scientific discovery? How should the
    integration of research and training among
    computer science, mathematical science, and the
    biological and physical sciences best be achieved
    to assure the effective use of computational
    science methods and tools?
  • How effectively do Federal agencies coordinate
    their support for computational science and its
    applications in order to maintain a balanced and
    comprehensive research and training portfolio?
  • How well have Federal investments in
    computational science kept up with changes in the
    underlying computing environments and the ways in
    which research is conducted? Examples of these
    changes might include changes in computer
    architecture, the advent of distributed
    computing, the linking of data with simulation,
    and remote access to experimental facilities.
  • What barriers hinder realizing the highest
    potential of computational science and how might
    these be eliminated or mitigated?

  • written testimony accessible at www.nsf.gov
  • Eric Jackobsson, Center for Bioinformatics and
    Computational Biology, NIH
  • for Elias Zerhoni, Director, NIH
  • Michael Strayer, DOE
  • for Ray Orbach, DOE Office of Science
  • Ken Kennedy, Rice
  • former PITAC co-chair
  • Kennedys testimony
  • retrospective on PITAC and agency responses

1999 PITAC Principal Finding
  • Drift away from long-term fundamental research
  • agencies pressed by the growth of IT needs
  • IT RD budgets have grown steadily but not
    dramatically
  • IT industry has accounted for over 30 percent of
    the real GDP growth over the past five years, but
    gets only 1 out of 75 Federal RD dollars
  • problems solved by IT are critical to the nation
  • engineering design, health and medicine, defense
  • Most IT RD agencies are mission-oriented
  • natural and correct to favor the short-term needs
    of the mission
  • This trend must be reversed
  • continue the flow of ideas to fuel the
    information economy and society

1999 PITAC Recommended Remedy
  • Increase the Federal IT RD investment
  • by 1.4 billion dollars per year
  • ramp up over five years
  • focus on increasing fundamental research
  • Invest in key areas needing attention
  • software
  • scalable Information Infrastructure
  • high-end computing
  • social, economic, and workforce Issues
  • Develop a coherent management strategy
  • establish clear organizational responsibilities
  • diversify modes of support

1999 PITAC Funding Recommendations
  • Increase current funding for IT RD as follows

Kennedy Observations
  • PITAC 1999 message focus on long-term research
  • think big and make it possible for researchers to
    think big
  • increase the funding and the funding term
  • unique responsibility of the Federal Government
  • Positive result funding has increased
  • most of the measurable growth has gone to NSF
  • modes of funding diversified
  • new programs initiated
  • Concerns
  • HPC software still not getting enough attention
  • amounts and nature of funding
  • Is the leadership and management adequate?
  • Are we returning to an era of short-term thinking?

Whats Next
  • Subcommittee work starts in earnest
  • meetings, workshops, one-on-one interviews
  • agency discussions and information gathering
  • Report target
  • February 2005
  • How can you help?
  • talk to committee members informally
  • share position documents
  • issues, needs, opportunities,
  • start community discussion
