# Presentation: 476265

## Atlas CAP Closeout

- Thanks to all the presenters for their work in preparing documentation, presentations, web sites, and demos!
- Personal thanks for tolerating my “inability” to travel

## Project Overall

- The excitement is building – real data is now only a year away!
- U.S. Atlas (and International Atlas) have made good and encouraging progress in the past 12 months
- Budgets remain very tight (as always)

## Management (1)

- Overall, the management of the Software & Computing part of the research program appears healthy...
- Leadership is clearly engaged within the U.S. project, within International ATLAS, and in related grid projects

## Management (2)

- (Formal) Change Control has made progress in the last 12 months
- Process is being used
- Triggers are better defined
- ...but there is still room for improvement so that it becomes a useful management tool.
- Once again multiple changes were rolled into an aggregate “omnibus” change, which is not a recommended approach.
- Recommendation: Utilize Change Control more formally, even allowing documented requests to appear earlier that may or may not be approved, or may be deferred.

## Management (3)

- For FY2007, an adequate management reserve is being maintained.  For FY2008, it is ephemeral, in that the computing project needs are of the scale of the full reserve (i.e. there is no reserve).
- The leadership did state that the currently unfunded (held in management reserve) components would have to compete for the funds (hence cannot be assumed).
- Full Dress Rehearsal is a concern; we encourage management to review carefully goals & readiness, and interact with International ATLAS if it appears too ambitious (partitioning may be needed).

## Facilities (1)

- There has been healthy growth in all aspects of facilities this year
- Tier 1 capacity growth
- Tier 1 staff growth
- Tier 1 network bandwidth upgrades
- Selection of final 2 tier 2’s
- SC 4 was a success. Achieved 200 MB/s sustained (average)
- Impressive: U.S. ATLAS contributed 28% of distributed event production; the BNL Tier 1 is recognized as doing very well.
- There are no procurement issues in 2007
- Starting in 2008-9, planned facilities growth is dependent upon consumption of 50% of the management reserve.
- In 2010, even that reserve will not be sufficient to maintain the goal of U.S. ATLAS additional capacity (beyond International ATLAS commitments)

## Facilities (2)

- There is no ATLAS specific cybersecurity plan.  The Tier 1 plans appear reasonable, but U.S. Atlas is dependent upon the Tier 2 sites (and OSG) to address the distributed cybersecurity problem.
- We endorse the goal of identifying cybersecurity manpower for ATLAS, and believe in the current culture it will become essential (even mandatory)
- We encourage the project to finalize plans with BNL for deployment space for 2009 and beyond.

## Distributed Computing (Grid)

- Impressive progress on Panda in the last 12 months, moving from a relatively new prototype (2 months old) to a rapidly maturing production tool.
- The next 12 months will be key as Panda makes opportunistic use of OSG resources.
- Engagement level w/ OSG has significantly ramped up.
- Full Dress Rehearsal is a concern

## Software (1)

- U.S. Atlas is involved at a healty level in event generators, infrastructure for tracking, calorimeter, muons, and monitoring
- We endorse the plans for a graphics programmer, and expect the need to continue at some level beyond 2 years
- Generator support may be needed in the out years (currently drops to 0 in 2008)
- Development of a Derived Physics Data format (standard) is encouraged, lest multiple formats emerge

## Software (2)

- The demos were very good!
- pathena demo convincing, showing that the system is now a reality
- status browsing harder for non expert to follow; more complex, lots of detail

## Analysis Support

- Great progress made in 2006
- better defined than a year ago
- many plans from a year ago have been realized
- Distributed model looks promising, good way to get more people involved
- Jamborees are popular, successful; congratulations on enthusiasm generated
- Services of ASG are not being taken advantage of fully yet.  If new staff is needed for the Jamborees, then proceed quickly.  Otherwise, pace to growth in demands for support.
- Need to address support for people at CERN
