122. 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/WorkBook-PATTutorial
132. 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
142. 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
152. Status of Data-Analysis
Batch system Check which queues you have access to using the command
bqueues -u <username>
