ATLAS Midwest Tier 2 University of Chicago Indiana

ATLAS Midwest Tier 2 University of Chicago Indiana University Rob Gardner Computation and Enrico Fermi Institutes University of Chicago WLCG Collaboration Board Meeting February 3, 2006 2/3/06 R. Gardner - MWT 2 Status

MWT 2 Description n Midwest Tier 2 center is a joint project between UC and IU q q q n n Project is building from i. VDGL prototype Tier 2 centers, which are now in place and have been active in ATLAS DC 2 and Rome production Three dedicated project FTEs hired, 2 in place now q q n to provide a computing resource for Monte Carlo production facilitate physics analysis of AOD samples To present this as a single service to ATLAS physicists, abstracting away site differences Marty Dippel @ UC; Kristy Kallback-Rose @ IU Dan Shroeder to arrive 2/06 @ IU. Continued contributions from Andrew Zhan (Gri. Phy. N/i. VDGL) and from Greg Cross (UC Teraport project) 2/3/06 R. Gardner - MWT 2 Status 2

Current Scale - Chicago n n n 64 dual 3. 0 GHz Xeon nodes, 2 GB memory Interconnected by Cisco Catalyst 3750 G A storage system consists of four servers with dual 3 Ware disk controllers, providing 16 TB of attached RAID storage. Eight front-end nodes provide grid GRAM and Grid. FTP servers from VDT (OSG and OSG Integration testbed gateways) The facility also has interactive login nodes to support local batch analysis that we are providing on a best effort basis until official US ATLAS Tier 2 policies are developed. 4 machine development cluster (Rocks and Condor configuration trials, OSG integration testbed) 2/3/06 R. Gardner - MWT 2 Status 4

Current Scale - Indiana n n n The prototype Tier-2 consists of dedicated use of 64 2. 4 GHz Xeon processors possible through an in-kind contribution by IU (AVIDD, NSF-MRI) to ATLAS. The site has 1. 5 TB of dedicated fiber channel disk. Additional 8. 0 TB of Network Attached Storage for ATLAS production use. Archival tape system New MWT 2 equipment will be located at the ICTC machine room on the Indianapolis campus of IU (IUPUI) 2/3/06 R. Gardner - MWT 2 Status 5
