The following is an example of the error mpicasa produces when running in HTCondor and ${HOME}/.matplotlib isn't already populated. This happens when, for example, we set HOME=${HOME:=$TMPDIR} because we are running on a remote site or simulating it. We have to set HOME to something because mpicasa expects it and HTCondor doesn't set HOME by default.
After many attempts to get matplotlib to generate its own .matplotlib, the results were always inconsistent. So, the solution was to add a poplulated .matplotlib directory to transfer_input_files for each DAG or job.
471 raise RuntimeError("Failed to create %s/.matplotlib; consider setting MPLCONFIGDIR to a writable directory for matplotlib configuration data"%h)

OSError: [Errno 17] File exists: '/lustre/aoc/admin/tmp/condor/nmpost071/executedir_130008/.matplotlib'
In [2]: Do you really want to exit ([y]/n)?
--------------------------------------------------------------------------
casa has exited due to process rank 1 with PID 130184 on
node nmpost071 exiting improperly. There are three reasons this could occur:
1. this process did not call "init" before exiting, but others in
the job did. This can cause a job to hang indefinitely while it waits
for all processes to call "init". By rule, if one process calls "init",
then ALL processes must call "init" prior to termination.
2. this process called "init", but exited without calling "finalize".
By rule, all processes that call "init" MUST call "finalize" prior to
exiting or it will be considered an "abnormal termination"
3. this process called "MPI_Abort" or "orte_abort" and the mca parameter
orte_create_session_dirs is set to false. In this case, the run-time cannot
detect that the abort call was an abnormal termination. Hence, the only
error message you will receive is this one.
This may have caused other processes in the application to be
terminated by signals sent by casa (as reported here).
You can avoid this message by specifying -quiet on the casa command line.
