## U.S. ATLAS Testbed Status Report

- Kaushik De
- Univ. of Texas at Arlington
- BNL Workshop, May 2002

## Outline

- 2 week assessment
- Goals
- Planning
- Work organization
- teams
- details
- recent accomplishments
- SC2002: 6 month plan
- 12 month plan

## Assessment

- Testbed Strengths
- Excellent package manager
- Information service plans ready
- Advanced grid portal
- Database manager ready
- Lots of existing hardware
- Experienced people
- Testbed Weaknesses
- Middleware outdated - Globus 1.1.3
- Waiting for other middleware
- No applications, no interfaces
- 8 independent sites
- Need concrete plans for deployment
- Need concrete short term goals

## Testbed Goals

- Demonstrate success of grid computing model for HEP
- in data production
- in data access
- in data analysis
- Develop & deploy grid middleware and applications
- layered structure
- ease of deployment
- Evolve into fully functioning scalable distributed tiered grid

## Testbed Plans

- UTA Workshop as launch-pad
- for testbed middleware upgrade
- to identify tasks & organize effort + resources
- SC2002 as milestone
- demonstrate real working HEP grid applications
- demonstrate middleware and tools developed for HEP
- component integration
- demonstrate inter-operability among experiments

## UTA Workshop

*http:/heppc1.uta.edu/atlas/workshop_april_2002/*
- 21 talks, 8 discussion sessions
- 8 page tasklist

## Testbed Tasklist

- Middleware deployment
- OS, Globus, Condor...
- Physics application deployment
- Information services (MDS)
- Middleware development
- Data production & access
- Integration & testing
- Analysis tools
- Success must be measured by ease of deployment and usefulness to physicists

## Hardware

- Farms - BNL, LBNL, IU, UTA
- +Multiple R&D gatekeepers
- gremlin@bnl - iVDGL GIIS
- heppc5@uta - ATLAS GIIS
- atlas10/14 - EDG testing
- heppc6@uta+bnl - glue schema
- heppc17/19 - GRAT devel
- @iu - Grappa portal
- ? - iVDGL-2 testbed
