=================================

We use the same mechanisms as MPI to launch LCI, so you can use the same way you run MPI parcelport to run LCI
parcelport. Typically, it would be ``hpxrun``, ``mpirun``, or ``srun``.
parcelport. Typically, it would be ``hpxrun.py``, ``mpirun``, or ``srun``.

If you are using ``hpxrun.py``, just pass ``--parcelport lci`` to the scripts.
``hpxrun.py`` serves as a wrapper for ``mpirun`` and ``srun``.
If you are using ``hpxrun.py``, pass ``-p lci`` to the scripts. You also need to pass either ``-r mpi`` or
``-r srun`` to select the correct run wrapper according to the platform.

If you are using ``mpirun`` or ``srun``, you can just pass
``--hpx:ini=hpx.parcel.lci.priority=1000``, ``--hpx:ini=hpx.parcel.lci.enable=1``, and
``--hpx:ini=hpx.parcel.bootstrap=lci`` to the |hpx| applications.

The ``hpxrun.py`` argument ``-r none`` (the default option for the run wrapper) and its corresponding |hpx| arguments
``--hpx:hpx`` and ``--hpx:agas`` do not work for the MPI or the LCI parcelport.
