If you are doing depletion analysis, you may have to set
.. code-block:: python
openmc.deplete.pool.USE_MULTIPROCESSING = False
in your python file before making any calls to the integrator depending on whether
or not your MPI is compatible with forking (e.g., see the `OpenMPI FAQ entry about
forking <https://www.open-mpi.org/faq/?category=tuning#fork-warning>`_). If it is
not compatible, and this in not set, random hangs and crashes can result.

Depletion
*********
If you are running a depletion simulation and are experiencing random hangs or
crashes, you may need to set::
openmc.deplete.pool.USE_MULTIPROCESSING = False
in your Python file before making any calls to the integrator. This can be
caused by an MPI implementation that is not compatible with forking (e.g., see
the `OpenMPI FAQ entry about forking
<https://www.open-mpi.org/faq/?category=tuning#fork-warning>`_).
