GENERAL CONSIDERATIONS
(1) Challenge is for Fusion SciDAC projects to
effectively utilize terascale computing to
produce significant new scientific
insights/conceptual breakthroughs that are well
appreciated by the FES as well as the general
scientific community (2) Need to clearly
demonstrate how the partnerships with CSET (e.g.,
in the OASCR-funded Fusion SciDAC Collaboratory)
is delivering new capabilities --
collaboratively building the necessary software,
visualization, networking, etc. to enable
effective use of hardware to accelerate
scientific progress (3) Fusion SciDAC Program
should demonstrate how it can play a key role in
helping to make case for future experimental
facilities such as ITER -- cost-effective
assessment of new ideas and operating
scenarios -- impact real decision-making in the
large scientific options space

CHARGE FOR PSACI PAC MEETING___________________
______________________

• Assessment of the accomplishments of the Fusion
  SciDAC Projects
• How has each project made tangible progress
  toward achieving scientific targets proposed by
  Fusion SciDAC centers/projects?
• How have high-end computing resources been
  effectively utilized to accelerate progress
  toward achieving these goals?
• Are productive collaborative activities evident
  within each project and with other SciDAC
  activities (including relation between projects
  and enabling technology resource centers)?

Collaboratory Goals -- enable more efficient
use of experimental facilities by developing more
powerful between pulse data analysis -- enable
better access by researchers to analysis
simulation codes, data, and visualization
tools -- create standard tool set for remote data
access, security, and visualization
Collaboratory Partners -- 3 large fusion

CHARGE FOR PSACI PAC MEETING___________________
______________________

• Consider and provide guidance on the key areas
  targeted in the next 3-year phase of the FES
  SciDAC Program (beginning in June of 04)
• What is the likelihood of timely delivery of
  significant new scientific insights/conceptual
  breakthroughs enabled by the FES SciDAC Program?
• What is the likelihood of timely delivery of
  reliable computational modeling capabilities
  addressing burning plasma physics issues relevant
  to ITER?
• How can the FSP (Fusion Simulation Project)
  component of the FES SciDAC Program best be
  organized to successfully achieve the targeted
  goals of this new effort.

INTEGRATED MODELING U.S. Fusion Community has
proposed Fusion Simulation Project (FSP)

• Endorsed by US Fusion Energy Science Advisory
  Committee (FESAC) and DOE
• Proposed 20M/yr with start-up planning activity
  in FY 05 at about 2M
• Plan to leverage results from SciDAC Program for
  fundamental physics foundations and on Applied
  Math/Computer Science communities for needed
  algorithms
• Fusion Simulation Project is a potentially
  valuable US contribution to ITER
