Or, in 6.7.1 or later, you can add
noop_job = true
to your submit file and Condor will do everything but actually run
your job when you submit it (the submit and terminate events are present)
You could also send a SIGSTP to the DAGMan process running your job, which
woudl prevent it from submitting any new jobs. One problem that you'd
have is that the schedd will eventually kill your DAGMan when it stops
reporting that it's alive. (You can hack around this)
Otherwise, there's really no way to control the flow through the DAG after
DAGMan has started.
