UTA Site Report

The University of Texas at Arlington (UTA) is advancing its involvement in the ATLAS experiment, co-led by Kaushik De and Jae Yu, focusing on the development of a distributed analysis framework called Panda. The workshop highlighted the capabilities of UTA's computing resources, including the DPCC facilities and collaboration with multiple disciplines. UTA's significant hardware investments enhance analysis and data management for ATLAS. As UTA transitions from DØ to ATLAS, new networking capacities are expected to boost future projects and innovative computing methods.

  1. UTA Site Report Jae Yu Univ. of Texas, Arlington 2nd DOSAR Workshop UTA Mar. 30 – Mar. 31, 2006

  2. Introduction • UTA has been focusing on conversion to ATLAS experiment • Kaushik De is co-leading development of distributed analysis framework – Panda • Part of ATLAS SW Tier 2 is at UTA • Its phase I implementation in progress • Jae Yu is participating in developing distributed analysis leg of panda • Along with distributed analysis monitoring based on MonALISA • UTA is a member of HiPCAT, a Texan grid organization • HEP group working with other discipline in shared use of existing computing resources, notably DPCC

  3. UTA Swift Farm • Hardware capacity • 38 CPU’s of P3 900MHz • Total Disk: 0.5TB • Memory: 250MBytes/cpu • Produced and delivered over 4 million events 2003 - present • This farm has retired from the participating in active production • Turned to a test farm

  4. UTA DPCC • UTA HEP-CSE + UTSW Medical joint project • NSF MRI supported • Hardware Capacity • Linux system • 197 CPU’s of mixture of P4 Xeon 2.4 – 2.6 GHz • Total disk: 76.2TB • Total Memory: 1GB/CPU • Network bandwidth: 68Gb/sec • Additional equipment will be purchased (about 2 more racks) • 3 IBM PS157 Series Shared Memory system • 8 1.5GHz Power5 processors • 32 GB RAM • 6 140GB Internal Disk drives • 1 2Gb fibre Channel Adapter • 2 Gigabit Ethernet Nics

  5. UTA DPCC • Participated strongly on DØ and ATLAS MC production as well as DØ data reprocessing • Other disciplines also use this facility • Biology, Geology, UTSW medical, etc • Converted over for more focused ATLAS tasks • Will use opportunistic computing tactics for DØ and other Tasks

  6. ATLAS SW Tier 2 • Joint effort between (UTA, OU, LU and UNM) • Two locations: at UTACC – Phase I and at CPB

  7. Network Capacity • Had DS3 (44.7MBits/sec) till late 2004 • Increased to OC3 (155 MBits/s) early 2005 • Now at OC12 • Expected to be connected to NLR (10GB/s) through LEARN soon (http://www.tx-learn.org/) • $9.8M ($7.3M for optical fiber network) state of Texas funds approved in Sept. 2004 • Initial implementation completed

  8. Software Development Activities • Initial effort put in for DIAL, interactive distributed analysis system • MonALISA based ATLAS distributed analysis monitoring • The feasibility has been investigated • Scalability has been tested within the UTA domain • Mariam John will cover the details • We are hiring a postdoc/software specialist to focus on development of the distributed analysis system • Will work closely with the Panda team

  9. CSE Student Exchange Program • Joint effort between HEP and CSE • David Levine is the primary contact at CSE • Two CSE MS Students each have worked in SAM-Grid team • Five generations of the student • PPDG project ending • New program with BNL being implemented • First set of the students will begin this summer • Two CSE MS or UTA Honor College Seniors • Will participate in ATLAS distributed computing projects • Write theses for documentation

  10. Physics Analyses • Higgs search - JY • One Ph.D. Student already resident at CERN • Participating in e-ID development using H-matrix technique • Can use DOSAR resources • SUSY search – KD and AW • One other Ph.D. student is getting ready to go to CERN • Diffractive physics and QCD – AB • Working with ATLAS for detectors and physics

  11. Conclusions • UTA’s initial transition from DØ to ATLAS has been successfully completed • ATLAS distributed analysis and development work started • Physics analysis also picking up speed • The new network capacity (hope to be in place in the next 2 years) of 10GB/s will give a big boost • Our activities naturally integrates into the role of DOSAR
