 When properly configured, Open MPI 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``.  Open MPI will use PBS/Torque-native mechanisms
+options to ``mpirun``.  Open MPI will use LSF-native mechanisms
 to launch and kill processes (``ssh`` is not required).
 
 For example:
 
-.. error:: TODO Need LSF specific content here
-
 .. code-block:: sh
 
-   # Allocate a PBS job with 4 nodes
-   shell$ qsub -I -lnodes=4
+   # 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]" "mpirun mpi-hello-world"
 
-   # Now run an Open MPI job on all the nodes allocated by PBS/Torque
-   shell$ mpirun mpi-hello-world
 
 This will run the MPI processes on the nodes that were allocated by
 LSF.  Or, if submitting a script:
 
-.. error:: TODO Need LSF specific content here
-
 .. code-block:: sh
 
    shell$ cat my_script.sh
    #!/bin/sh
    mpirun mpi-hello-world
-   shell$ qsub -l nodes=4 my_script.sh
+   shell$ bsub -n 8 -R "span[ptile=2]" < my_script.sh
