Real CRAB

Hint for good job

  • If you want to store data at castor, before submit CRAB you should do following first. (ex: stored directory : /castor/cern.ch/user/h/hckim/JulyExercise10/JulyExercise10_HardEnriched_Dilepton_skim0)
    • rfrm -r /castor/cern.ch/user/h/hckim/JulyExercise10/JulyExercise10_HardEnriched_Dilepton_skim0
    • rfmkdir /castor/cern.ch/user/h/hckim/JulyExercise10/JulyExercise10_HardEnriched_Dilepton_skim0
    • rfchmod 775 /castor/cern.ch/user/h/hckim/JulyExercise10/JulyExercise10_HardEnriched_Dilepton_skim0

  • At MIT, maximum capacity to process job is about 2000, so it will be good to reduce the number of job per task. In my experience, less than 200 is OK.

  • Because of unknown reason, sometimes crab submit can be failed with exit code 60307. That means the folder to store data doesn't have permit to write by group. At that time, please remove that folder, kill that job and create and submit new job.
  • If you face to exit code 8018, do following list. (ex : trouble job : 13, 119)
    • crab -get(or -getoutput) 13, 119
    • crab -resubmit 13, 119
