Ntuple Structure:

Data Storage

Setup

  • The storage h/w is pcdream:/mnt/storage
    • It is a 3 TB external disk connected to pcdreamdaq2
  • The storage element at TTU
    • Used to mirror, via GlobusOnline, the pcdream:/mnt/storage/ disk
    • ~Daily TTU mirror procedure: Note: REQUIRES the TTU endpoint to be activated by Michele, Sehwook or Alan by grid proxy ahead of time to work
      • Login to the dreamtest account on pcdreamdaq2, or to any other account that has ssh keys stored in the Globus dreamdaq identity store
      • Execute: ssh -t dreamdaq@cliNOSPAMPLEASE.globusonline.org scp -r -s 0 -v pcdreamdaq2personal:storage/ TTU-Sigmorgh-DREAM:/lustre/hep/osg/dream/2015/
    • The script ~/bin/ttuls from the dreamtest directory (on pcdreamdaq2) lists files hosted in the storage element at TTU. The bin area is in the path for the dreamtext account, so the command ttuls should work without prefix.
      e.g.: ~ttuls data or ttuls data/datafile_run100*.dat for a limited range, etc.
    • How to retrieve data by anyone in DREAM from the storage element at TTU: .see GridHelp / GridSetup / GlobusOnline / DataTransfer pages

    • Where are the data files?

    1. In pcdreamdaq2:~dreamtest/storage/
    2. In a disk at TTU. Use the ttuls data script to lists them (How to copy ntuple on your PC)

    Where are the pedestal files?

    1. In pcdream:/mnt/storage/pedestal
    2. In a disk at TTU. Use the ttuls pedestal script to lists them (How to copy ntuple on your PC)

    Where are the ntuple files?

    1. In pcdreamdaq2:/mnt/storage/ntuple
    2. In a disk at TTU. Use the ttuls ntuple script to lists them (How to copy ntuple on your PC) 

    [pcdream] /home/dreamtest/working/ntuple >              DRS 32 channels
[pcdream] /home/dreamtest/working/ntuple/silvia >     DRS read with 16 channels

    Example macros

    A few example macro to analyze the DREAM ntuples.
