Launching with LSF
==================
PRRTE supports the LSF resource manager.
Verify LSF support
------------------
The ``prte_info`` command can be used to determine whether or not an
installed Open MPI includes LSF support:
.. code-block::
shell$ prte_info | grep lsf
If the PRRTE installation includes support for LSF, you
should see a line similar to that below. Note the MCA version
information varies depending on which version of PRRTE is
installed.
.. code-block::
MCA ras: lsf (MCA v2.1.0, API v2.0.0, Component v3.0.0)
Launching
---------
When properly configured, PRRTE obtains both the list of hosts and
how many processes to start on each host from LSF directly. Hence, it
is unnecessary to specify the ``--hostfile``, ``--host``, or ``-n``
options to ``mpirun``. PRRTE will use LSF-native mechanisms
to launch and kill processes (``ssh`` is not required).
For example:
.. code-block:: sh
# Allocate a job using 4 nodes with 2 processors per node and run the job on the nodes allocated by LSF
shell$ bsub -n 8 -R "span[ptile=2]" "prterun mpi-hello-world"
This will run the processes on the nodes that were allocated by
LSF. Or, if submitting a script:
.. code-block:: sh
shell$ cat my_script.sh
#!/bin/sh
prterun mpi-hello-world
shell$ bsub -n 8 -R "span[ptile=2]" < my_script.sh
