Check Which Tags Are In A CMSSW Release

  • look into /afs/cern.ch/cms/sw/slc5_compiler/cms/cmssw/CMSSW_X_Y_Z/src/PackageList.cmssw, e.g. /afs/cern.ch/cms/slc5_amd64_gcc462/cms/cmssw/CMSSW_6_0_0_pre2/src/PackageList.cmssw

OR

* from https://cmstags.cern.ch/tc/, select the release and the Show All Packages option and then click on the submit button

Check Which Global Tag Was Used To Process A Data File

edmProvDump rfio:rootfile | grep globaltag

Find The Most Up-To-Date JSON file

  • on afs at /afs/cern.ch/cms/CAF/CMSCOMM/COMM_DQM/certification/Collisions11/7TeV/
  • on the web here

How to check a trigger path description

Info taken from the following hypernews, https://hypernews.cern.ch/HyperNews/CMS/get/hlt/2640/1/1.html.

When you open a menu there's a "Summary" tab at the upper right that if you click will try to display only the thresholds/cuts used in the last filter modules in the HLT paths.

and then follow the links to "HTML view of physics algorithms and scales"

How to check when a particular trigger path was prescaled

edmConfigFromDB --runNumber 136132 | hltDumpStream | grep '\<HLT_L1MuOpen\>' | head -n1

How To Resubmit a specific job on CRAB

  • if the status of the jobs in question is "Killed", "Aborted" or "Done" and the "Exit_Code" is not 0, they can be resubmitted immediately with the same executable and the same settings by
    crab -resubmit job-id -continue crab_?_date_time where job-id can be a single crab job-id, a comma separated list of job-id's or a range of job-id's from the status check.

  • To resubmit all "failed" jobs at once (ignoring jobs with "Done" or "Cleared" status)
    crab -resubmit -continue crab_?_date_time

  • IMPORTANT: if the status is "Done" and the "Exit_Code" is not 0, the user has to retrieve the job output before he can resubmit the job
