Outline

• A brief review of Reviews
• What this review is
• What this review isnt
• Review procedures
• Charge to Committee

3
A Brief Review of Reviews

• DOE/NSF ad hoc peer reviews of US LHC software
  and computing started c. 1998
• Provided periodic input to agencies before formal
  beginning of SC Projects
• Most recent Jan. 2000 _at_ DOE
• Also CERN Management Review of LHC Computing
  (Hoffmann Review) in 2000
• This week US Baseline Review

4
What this review is

• A critical evaluation of scope, cost, schedule,
  and project management
• Establishment of near-term project baselines in
  these areas
• An important input to FY2001-2 budgets
• The beginning of a regular, systematic review
  process (a la LHC Detectors)

5
What this review isnt

• An attempt to set long-term project
  baselinesmany things will change
• A construction project Lehman Review
• What are the right metrics?
• An exercise in herding cats
• HEP Computing is on the radar screen

Review Procedures

• Overview sessions today, Wed, Thurs.
• Breakout sessions software, facilities, project
  management (ATLAS/CMS)
• Subcommittees tailored to breakouts
• Closeouts CMS (Wed), ATLAS (Fri)
• Administrative Andreene Witt 1-37 Jackie
  Mooney 1-45

Charge to Review Committee

• we are requesting a detailed technical, cost,
  schedule and management review of only the
  near-term project efforts, up through Fiscal Year
  2002. However, the review committee should make
  its best effort to gauge whether these near-term
  efforts can reasonably be extrapolated to the
  long-term requirements.

Charge to Review Committee II

• The charge for this reviewisto assess
• Overall strategy and scope of US LHC SC
• US contributions to core and detector-specific
  software deliverables
• Function, scope structure of national
• US LHC computing facilities (Tier 1)
• Other aspects of computing structure (e.g.,
  Tier 2, grid computing, networking)

10
Charge to Review Committee III

• Plans for providing computing resources to users
  and success in integrating them into the software
  development process
• Existing and possible common projects
• Project Management Plans, org. structures, and
  adequacy of personnel to pull off the whole
  enchilada

11
Summary

• This review will establish project baselines for
  US LHC software and computing
• We will employ project management tools but we
  realize SC projects are different
• This is a learning process
• Failure is not an option.
• Comments and suggestions are welcome!
