Jobsub Wrapper Script

Overview

Jobsub actually submits to condor a wrapper script which calls the executable you specify on the jobsub_submit command line. This document describes that wrapper script, which is generated from the template templates/simple/simple.sh

Startup actions

Initially the wrapper sets

  • umask to 0022
  • clears environment variables that sites set that they shouldn't
    • CPATH
    • LIBRARY_PATH
  • Sets BEARER_TOKEN_FILE to the token file condor pushes
  • makes a .empty_file file.
  • sets temp dir related variables: JSB_TMP,_CONDOR_SCRATCH_DIR,TEMP,TMPDIR based on initial _CONDOR_SCRATCH_DIR
  • sets up CONDOR_DIR_INPUT
  • sets up ifdhc
  • copies in files specified with -f on the jobsub_submit command line
  • copies in (if needed) unpacks, and set INPUT_TAR_FILE, INPUT_TAR_FILE_1, etc. for --tar-file-name
  • makes JOBSUB_OUT directories for -d parameters
  • Does per-experiment custom config

Running the executable

  • finds the executable from the jobsub command line, which got copied in with the job
  • logs a message about starting the exectable
  • runs executable
  • logs message about completion

Finalize actions

  • generates truncated stdout, stderr files to prevent overflowing copy back
  • copies out -d files
