Renaissance Computing Institute
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?

– Eric Jackobsson, Center for Bioinformatics and
Computational Biology, NIH
• for Elias Zerhoni, Director, NIH

– retrospective on PITAC and agency responses
Renaissance Computing Institute
1999 PITAC Principal Finding
• Drift away from long-term fundamental research
– agencies pressed by the growth of IT needs
• IT R&D 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
R&D dollars
• problems solved by IT are critical to the nation
– engineering design, health and medicine, defense
– Most IT R&D 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 R&D 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

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?

What’s 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
