## U.S. ATLAS Computing Project: Budget Profiles, Milestones

**Jim Shank**
**Boston University**
- Physics and Computing Advisory Panel Review
- LBNL
- 14-16 Nov., 2002

## The last 2 days...

- Workshop to prepare the 2003 NSF ITR proposal
- Large ITR: $15M over 5 years
- Joint ATLAS/CMS + Computing Sciences
- The Workshop was charged with identifying a critical area of computing needed for LHC that was not being funded by exsting programs
- Participants from a wide spectrum
- LCG project
- EDG project
- Trillium (GriPhyN, iVDGL, PPDG)
- CMS/ATLAS communities
- Some other physics experiments...
- 2 Working groups:
- The BIG Picture group
- The ITR group

## Categories of missing pieces

- Transition to production level grids (middleware support, error recovery, robustness, 24x7, monitoring and system usage optimization, strategy and policy for resource allocation, authentication and authorization, simulation of grid operations, tools for optimizing distributed systems)
- Globally Enabled Analysis Communities (WG2)
- Enabling Global Collaboration (a medium ITR?)

- Slide from WG1 Summary
- (I. Gaines)

## Who Fills in Missing Pieces

- Experiments (from existing budgets) (but remember gap between bare bones funding level and originally proposed leadership funding level)
- LCG (from existing funding)
- Current grid projects (both connected to HEP and more general projects)
- Near future grid projects
- This large ITR: Globally Enabled Analysis Communities
- Additional medium ITR (?): Enabling Global Collaboration

## Globally Empowered Analysis Communities: think globally, act locally

- User Grid Interactions (Mike, Bolek, Craig, Shaowen)
- data browsing tools
- User Interfaces
- Visualisation Tools
- Education outreach
- Interactive tools
- Developing automation (Higher level services, AI)
- Dynamic Resource Control (Sridahara, Kaushik, John)
- Resource scheduling
- job scheduling
- environment control
- resource auditing, priority and priv.
- Data Provenance and workflow (Mike, Rick, David Adams)
- Community sharing and collaboration
- metadata management and tools (Greg and Jaideep, David Malon)
- specification of data sets
- spec. of user analysis
- queries (metadata browser)
- Equivalence
- Data Management (Ian, Torre)
- storage and data management
- data management optimisations (Obj. level)

- Slide from WG2 Summary
- (R. Cavanaugh)

## Template for summarising the different Topics

- Make a strong connection to the use cases
- how it is different from existing projects
- why it is new and revolutionary
- Status of Topic
- Description of abilities
- Generalisation beyond HEP
- How it ties into Title

- Slide from WG2 Summary
- (R. Cavanaugh)

- David R. Quarrie, LBNL               PCAP Review

## Still need...

- $15M spread over 5 years
- scope needs to be consistent with this
- Need deliverables
- Need designated editors for text
- Rob Ed., Ruth assists
- Need list of participants

- Slide from WG2 Summary

## Summary

- Great progress/success with the Data Challenges.
- US ATLAS Testbed has become MUCH more functional
- Driven by DC and the SuperComputing 2002 demonstrations taking place next week
- Interactions with CERN
- ATLAS interaction with LCG needs strengthening although US is quite active.
- International ATLAS responding positively to our pressure: SIT
