SWT2 Growth Courtesy M. Ernst US ATLAS Transparent Distributed Facility Workshop 3/04/08 4/17/2008

ATLAS SWT2 Capacity Current Capacity for Project Funded Resources Total CPU ~ 1,200K SI2K Total Disk ~ 92TB (usable) Additions to SWT2_CPB Total CPU ~ 2,200K SI2K Total Disk ~ 300TB (usable) Future Purchases will be weighted more to storage growth 4/17/2008

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 4/17/2008

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 brought back into service for OSG at UTA Completed a DDM monitoring project Working on Achelois, the ATLAS Operations Support System 4/17/2008

CSE Student Exchange Program Joint effort between HEP and CSE David Levine, Gergley Zaruba and Manfred Huber are 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 4/17/2008

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 4/17/2008

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 4/17/2008
