1. K. De UTA Grid Workshop April 2002 U.S. ATLAS Grid Testbed Workshop at UTA Introduction and Goals Kaushik De University of Texas at Arlington

2. K. De UTA Grid Workshop April 2002 ATLAS Grid BNL  New paradigm for computing in HEP  Enable collaborative research and resource sharing in large international experiment using distributed computing techniques  Could be the foundation for next revolution in world-wide computing

3. K. De UTA Grid Workshop April 2002 U.S. ATLAS Grid Testbed Lawrence Berkeley National Laboratory Brookhaven National Laboratory Indiana University Boston University Argonne National Laboratory U Michigan University of Texas at Arlington Oklahoma University US -ATLAS testbed launched February 2001

4. K. De UTA Grid Workshop April 2002 Current Status  Eight participating sites running Globus 1.1.x for > 1 year  Tested inter-operability with ‘Hello World’ jobs  Developed and deployed new system tools - GridView, Gripe, PacMan, Magda  Need to move forward:  No user applications running on testbed machines ~90% idle  No user analysis tools  Need coordinated plan to upgrade testbed software  Need organized effort to develop user applications & tools  Need deployment schedule

6. K. De UTA Grid Workshop April 2002 Workshop Goals  General goals for the workshop  uniform deployment of VDT 1.0 at testbed sites  core software deployment at testbed sites (afs, local...)  participation in DC1 data generation (Tier 1, testbed, TeraGrid, other facilities)  plans for scheduling, monitoring, site policies etc.  status of US ATLAS tools like pacman, magda, grappa, gridview, gripe...  other user level grid tools for DC1 data analysis  other software issues/requirements for testbed sites

7. K. De UTA Grid Workshop April 2002 Workshop Plans  Assess available resources and develop plan for testbed hardware  Thursday morning session  Identify ATLAS application(s) for testbed deployment  Thursday after-lunch session  Plan software (toolkit) upgrade and deployment in testbed  Thursday late-afternoon session  Status of system tools  Friday morning pre-coffee break  Plan for summer 2002 demo  Friday morning post-coffee break  Final planning and talks on other grid experiences  Friday afternoon session  Hands on tutorial  Saturday morning session
