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Advanced grid portal Database manager ready Lots of existing hardware Experienced people Testbed Weaknesses Middleware outdated - Globus 1.1.3 Waiting for other middleware No applications, no interfaces 8 independent sites Need concrete plans for deployment Need concrete short term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

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 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

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

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

Hardware 8 gatekeepers - ANL, BNL, LBNL, BU, IU, UM, OU, UTA 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

Fabric Software Jason Smith, Saul Youssef, KD, Eric Myers Use kickstart for OS upgrade Upgrade to RH 7.2  Pacman to distribute software First stage deployment Globus, cernlib  JS & KD joined VDT team last week to facilitate use in ATLAS Second stage deployment Magda, GDMP, Condor...

Applications Team Horst Severini, KD… Start with Athena-atlfast afs based package - requires standard ATLAS distribution  Sandbox atlfast - generic site  Build sandboxed DC1 application package Released GRAT version 0.1 on 4/12/02  version 0.2 on 4/22/02  version 0.3 on 5/7/02
