 processes launched by mpiexec must therefore be equal to the product of number of ensemble members
 (3, in this case) with the number of processes to be used for each ensemble member (``M=2``, in this case).

 The subcommunicators in each ensemble member are: ``Ensemble.comm`` and ``Ensemble.ensemble_comm``.
 ``Ensemble.comm`` is the spatial communicator. ``Ensemble.ensemble_comm`` allows communication between
