1. U.S. ATLAS Testbed Status Report
Kaushik De
Univ. of Texas at Arlington
BNL Workshop, May 2002

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

3. Assessment Testbed Strengths Testbed Weaknesses
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Middleware outdated - Globus 1.1.3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

4. 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

5. Testbed Plans UTA Workshop as launch-pad SC2002 as milestone
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

6. UTA Workshop 21 talks, 8 discussion sessions 8 page tasklist
21 talks, 8 discussion sessions
8 page tasklist

7. Testbed Tasklist Middleware deployment Physics application 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
