U.S. ATLAS Physics and Computing Project Status John Huth Harvard University
Outline • Project Management Plan • Organization • Scope • Facilities • Software • Milestones • Budget
Projectization • Access/MS Project Database • Reporting/tracking function • Reporting Scheme • Formal reports quarterly • Written reports monthly • PCWS, PCWP, ACWP tracking (same as construction project) • Inputs from all Level 2 managers
PMP Overview • Description of ATLAS • CSG etc • Description of U.S. Organization • Job descriptions • Policies • Reporting and oversight • Working appendices • Budget • WBS • Deliverable list • Major Milestones

Advanced Information Technology Professional Information Technology Professional I Information Technology Professional II Information Technology Technician Student Travel Stores Space Power Low value materials High value materials Licenses Maintenance Consulting Technical services Administrative service Cost Categories
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
Software • U.S. Responsibilities • Control/framework • Data management • Major detector reconstruction • Liquid Argon Calorimeter • Tile Calorimeter • Muons • Status • Major milestones passed in creation of control/framework • 7 FTE software professionals working • Preparation for software agreements with ATLAS
Grid Computing • Petabyte scale virtual data grid • Hierarchy of centers (Tier 0 = CERN, Tier 1= BNL, Tier 2 = Universities) • Grid middleware linkages • Resource allocation and discovery • Security • Automation • Status • U.S. ATLAS testbed planning • Participation in GriPhyN, PPDG projects
U.S. ATLAS Testbed Boston University Esnet, Mren UC Berkeley LBNL-NERSC NPACI, Abilene Argonne National Laboratory Calren Esnet, Abilene, Nton Brookhaven National Laboratory Esnet Abilene Indiana University HPSS sites
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
Summary • Functional Organization • Software effort backbone of Intl. ATLAS • International ATLAS starting to coalesce • Grid tasks beginning • Funding profile must be addressed • PMP (minus WBS, budget) available for comment • Steps to projectization
