Disk space allocation directories for the Deuteron experiment. Directory paths marked with [*] are not confirmed as of Feb 09, 2023

For additional info on filesystems, see:

Hall C cdaq-cluster filesystems

1. main directory (for online analyzer, DBs, replay scripts, etc.):


2. output directory (ROOTfiles, REPORT_OUTPUT, PDF files, etc.):

  • Please do take special care to avoid modifying any files outside of your ~/deuteron-2023 directory.
  • File storage directories during the online analysis of Deuteron.
  • There is a README in the first directory with a few notes.
  • It is recommended to make a '~/deuteron-2023/go_analysis_deuteron' shell script that sets up your environment from scratch. For example, no changes/additions to anything in ~/bin, changes to init files like .tcshrc, .bashrc, etc, text editor config files, etc.

Farm/CUE disk allocations

/volatile/hallc/c-deuteron/            ( 4 TB high quota; 2 TB guarantee )
  • Files are NOT backed-up
  • Use for all large file output from analysis or simulation jobs. When guarantee threshold is exceeded it is possible to have files auto-cleaned up (removed). See policy:
  • Files you want to keep should be pushed to tape using jput
/work/hallc/c-deuteron/ directory ( 1TB  quota )
  • Files are NOT backed up.
  • Good place for analysis software, database files, etc.
  • These files should be in GitHub or have similar backups.
  • Nothing that matters should be stored only on /work.
/group/c-deuteron/ directory  still needs to be created   ( 100GB quota )
  • Backed up regularly.
  • Best place for analysis/replay scripts; software that is being actively developed, etc. (But, still use GitHub!)

Tape allocations

  • tape volume for analysis output (ie. simulation output, replay output that you want to keep long-term, etc.)
  • tape volume for raw data output (ie. production CODA files from the Hall)
  • Raw data are NOT accessible directly from tape. To make them accessible, they must be copied over to cache.
