ATLAS SWT2 (2007) SWT2-PH1@UTACC SWT2-PH2@UTACPB 320 Xeon 3.2 GHz cores = 940 GHz 2GB Ram/core = 640GB 160GB Internal/unit  25.6TB 8 dual core server nodes 16TB of storage assisted by 6I/O server Dedicated Gbit internal connections 200 Optaron 3.2 GHz cores = 640 GHz 2GB Ram/core = 400GB 8GB SATA /unit  4TB 8 dual core server nodes 75TB of storage by 10 Dell MD100 Raid assisted by 8 I/O servers Dedicated Gbit internal connections 9/27/2007

Network Capacity History at UTA Had DS3 (44.7MBits/sec) till late 2004 Choke the heck out of the network for about a month downloading D0 data for re-reconstruction Met with VP of Research at UTA and emphasized the importance of network backbone for attracting external funds Increased to OC3 (155 MBits/s) early 2005 OC12 as of early 2006 Connected to NLR (10GB/s) through LEARN (http://www.tx-learn.org/) via 1GB connection to NTGP $9.8M ($7.3M for optical fiber network) state of Texas funds approved in Sept. 2004 9/27/2007

LEARN Status 9/27/2007

NLR – National LambdaRail ONENET LONI LEARN 10GB/sec connections 9/27/2007

Software Development Activities MonALISA based ATLAS distributed analysis monitoring A good, scalable system Software development and implementation completed ATLAS-OSG sites are on the LHC Dashboard New server purchased for OSG at UTA  Activation to follow shortly Working on DDM monitoring project 9/27/2007

Centralized LHC Distributed Computing Monitor 9/27/2007

CSE Student Exchange Program Joint effort between HEP and CSE David Levine is the primary contact at CSE A total of 10 CSE MS Students each have worked in SAM-Grid team Five generations of the student Many of them playing leading roles in grid community Abishek Rana at UCSD Parag Mashilka at FNAL Sudhamsh Reddy working for UTA at BNL New program with BNL implemented First student on completed the tenure and is on job training Second set of two Ph.D. students at BNL Participating in ATLAS Panda project One student working on pilot factory using condor glide-in Working on developing middleware 9/27/2007

Conclusions MonALISA based panda monitoring activated New server needs to be brought up Working on DDM monitoring Will be involved in further DDM work Leading EG2 (photon) CSC note exercise Connected to 10GB/s NLR via 1GB connection to UTD Working closely with HiPCAT for State-wide grid activities Need to go back on to the LAW project but awaiting for successes at OU and ISU 9/27/2007
