  16. 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 • Most areas on LEARN lit • The “Last Mile” connection problem still exists

  20. CSE Student Exchange Program • Joint effort between HEP and CSE • David Levine, Gergley Zaruba and Manfred Huberare primary contacts 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 worked for UTA and back into Ph.D program • 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 and completing their tenure • Participating in ATLAS Panda monitoring project • One student working on pilot factory using condor glide-in • Finalizing the integration into the regular service • Facing some budget cut issues here

  21. The LAW Project • Co-Linux based Condor System OU established as the model • Had a meeting between OU team and UTA IT management in Feb. during the HiPCAT meeting • We are very grateful for the OU team willing to come and help • A team of UTA IT personnel designated to work on this project, looking into various aspects • Head of Academic Computing Services is the lead • Had a meeting with her two weeks ago • 28 new machine lab in Engineering as the trial case • IT wants to start with 5 machines or so first • IT will manage and support based software, OS and Co-Linux • All other software related responsibilities on HEP

  22. Conclusions • MonALISA based panda monitoring providing info to LHC Dashboard • New server was brought up Waiting for BNL to separate panda monitor servers out • Completed a project in DDM monitoring • Completed EG2 (photon) CSC note • Plan to connect to 10GB/s NLR via 1GB connection to UTD • Quite expensive to make the final connectio • Involved in ATLAS Computing Operations Support • Working closely with HiPCAT for State-wide grid activities • Started working on setting up a Co-Linux Condor Cluster
