UTA IAC MC Farm and Analysis Resources • Have two independent farms

– Swift farm (HEP)• 22 dual P3 900MHz• 250Mbyte/cpu• A total of .6TB disk space• Generated a total of 3.6M events w/ mcp14

– CSE Farm• 10 P3 900MHz cpu’s w/ 128M memory• Retired Split into two separate farms for CSE Grid computing project• Generated ~1M events w/ mcp14

• Analysis Machines– Four desktop machines of ~2GHz + 0.5GB each– Storage space ~0.4TB

UTA Software Products• McFarm Job control (Drew Meyer)

– As of this workshop, McFarmDST’s re-processed output are certified

• Ganglia resource monitoring (D. Jenkins)– Contains 7 farms (>350 CPU’s), including Tata institute, India

• McFarmGraph: Simulation production job monitoring system using gridftp (Aditya Nishanda, Sankalp Jain)– Provides detailed information for a MC request

• McPerM: MC Farm Performance Monitoring – Langston took this over

• Job Manager McFarm (JMM) for SAM/Grid interface (HyunWoo Kim)

UTA – RAC • Joint HEP and CSE project

– HEP DØ Regional Analysis Center– ATLAS DC Production– Grid 2003 test bed– Video streaming– Database research– Skin resin image database

• Brought online at the end of October, 2003• DØ MC Production begun at the end of Nov. 2003• Generated and delivered over 7M events

1.75M/Mo (Double the DØ capacity in 2003)

Future Projects• Through the end of May: Participate in TMBfix

#2 – 20% of the total will be fixed at DPCC– First step toward the analysis at UTA – RAC– The fixed TMB will be 100% stored at UTA

• McFarm (Meyer + Jenkins)– Incorporate TMB fix– Test RAW reprocessing in the summer– Improve performances– Develop utilities

Future Projects• Inclusion of JMM into SAM/Grid regular release• Installation of calibration database proxy at UTA• Participate in DØSAR grid MC production• MySQL McFarm Monitoring Database for both

McFramGraph and McPerM (Jenkins)• Automated MC Request download and production• Storage and refreshment of TMB data at RAC• Prepare for regional analysis

Conclusions• DØSAR has been the driving force for the great progress

last 6 mo• McFarm improvement is in its mature state

– Ready to participate in any DØ activities• SAM/Grid and McFarm are interfaced

– Official request is being processed • Some analyses have been performed at UTA IAC + RAC• UTA – RAC has been online for the past four months

Immediately doubled the entire DØ 2003 capacity • We are ready for grid based MC production• First proposal (PHANTOM) as the collaborative effort went
