+The ticket #31 tracks work on this. + {section: The problem: } We have actual users using Condor-C submit to submit hundreds or thousands of jobs with the same executable. For Condor-C copy_to_spool must be true. Furthermore, for Condor-C, we can't use clusters to share an executable; each job becomes a new cluster. You end up with one copy of the executable per job. Given a moderately large executable, you can end up with gigabytes of duplicate executables. This is a waste of disk space and bandwidth.
