+## Executing an MPI Job
 
 In this example we demonstrate how to wrap and execute an mpi hello world job with PSI/J. The base mpi command is `mpiexec -n 36 -ppn 36 echo Hello world`. This example is introducing the concept of a [job launcher](https://exaworks.org/psij-python/docs/programming.html#launchers), in this case **mpi**, e.g. `job.spec.launcher = "mpirun"`. The complete example script can be found [here](./).
