SKKULab - Meeting SKKU Lab-meeting, 28.April.2014 Dong-hyun Kim on behalf of the cern-904 team Department of physics, sungkyunkwan university, korea
Content 1. Status of Korea-Chambers 2. Status of Data-analysis
Status of Korea-Chambers • Complete constructed Korea-Chambers 8 – RE4/2 type, 2 – RE4/3 type • Finished all quality test at QC3 Visual test / Dark current test / Cosmic-ray test
2. Status of Data-Analysis • Support to Higgs to WW Work Event generation Massive production Using the lxbatch - Continuum - Signal - Interference Generate 400K Events for each data types Pythia simulation Detector simulation • - 7 & 8 TeV • Width(GeV) • 25 & 1 MC Signal Continuum Interference
2. Status of Data-Analysis • Representative Feynman graphs for the LO amplitude of gg->WW-> l(Higgs signal (a) and continuum background (b) contributions)
- G r a p h Total
- G r a p h OnPeak Head
- G r a p h Soulder Tail
2. Status of Data-Analysis • Study state • CMS Batch Job - http://information-technology.web.cern.ch/services/batch • CMS Software Framework • CMS PAT Tutorial - https://twiki.cern.ch/twiki/bin/view/CMSPublic/WorkBookPATTutorial
2. Status of Data-Analysis • Batch system • Scheduling system with access to many cores(farm) • User adds his jobs to the queue • Scheduling system starts jobs on one of the cores -> ATLAS and CMS users have a very small share on the CERN batch. All users are recommended to use the Grid, since their turnaround will be higher -> Limited by farm size
2. Status of Data-Analysis • Batch system • Submit a job in your home directory to the 1-hour queue bsub–q 1nh ~user1/jobs/job1.csh • Submit job2 with a 20MB memory limit (it is recommended to specify a memory limit) bsub–M 20000 job2 • Submit job3 to the 8-hour queue with a runtime limit of 120 minutes (it is recommended to specify a runtime limit) bsub -q 8nh -W 120 job3 • Run job4 on an SLC5 host bsub–R "type=SLC5_64" job4
2. Status of Data-Analysis • Batch system • Check which queues you have access to using the command bqueues -u <username>
