Project Office

Information in ACCESS DB Tracking functions automated Use of project office for procurements

Major procurements: 10% Mock Data Challenge (’03) 40% Facilities ramp (end of 04) 100% Facilities ramp (05)


Coordination with Intl. ATLAS

Common WBS, schedule Working to same milestones Trying to ramp up presence at CERN Multiple Tutorials given on

control/framework Software Agreements in progress

(control/framework is prototype agreement)


Contingency

Major issue: Funding profiles very tight Uncertainties large for a fixed set of

deliverables Factors of 2 or more in some cases

Adopt this model: “Build to cost” – drop requirements as

needed to meet deliverables Add 10% project reserve to help put deal

with crises – year by year allocation Agreement with CMS


Major U.S. Project Components

Regional Center at Brookhaven User support facility

Software “Core” software

Control/framework Data management

Detector Specific reconstruction Support, training

Physics Event generators, physics objects

Computational grids Tier 2 facilities


Regional Center

Goals: Support U.S. Physicists in analysis Support ATLAS Collaboration Hub of U.S. ATLAS Grid

Status: Support hires Center running, providing support Planning for ATLAS, Grid activities Acquisition of more Linux boxes

Support for CPU intensive jobs– Shielding calculations

– Trigger studies


Muon Level 2 Trigger

Radius of curvature map for muons.


Neutron Background Studies

Total neutron flux KHz/cm2

Challenges in Project Planning

“Projectizing” Accounting and tracking systems (DONE) Revision to Project Management Plan (DONE) Preparations for “Lehman” review (NOW)

Integration with International ATLAS Need more support functions at CERN (In

Progress) LHC Computing review (in progress)

Concerns about CERN IT division

Coping with funding profiles ($5M short integral) Poor match particularly in software Seeking relief in FY 02-04

Profile Effects

Substantial delay in services at Regional Center Mass Storage System support delayed until

FY 04. Impacts ability to perform ’03 Mock data

challenge

Software development can’t work with this profile Need flatter profile (FY 02-04) Still, integral eliminates all detector

specific tasks (mainly impacts universities)


Fallbacks

Overall: scale back on requirements Software:

Degree of grid automation Overall requirements

– (e.g. carrying two vs. one DB product) Shifting personnel

– (e.g. CERN location of SW pros)

Hardware Reduction of scope of RC… Delay of purchases – Moore’s law Alternative data-analysis strategies

Comment: user part of facilities is conservative
