MPI is only an interface (API) and there are multiple implementations
of MPI. KestrelHPC-openmpi module install openmpi on the frontend and
on the node image, and adds some event scripts which modify openmpi's
hosts file when a node is waken up, or when is shut down. This way you
can run mpi jobs over all the connected nodes without having to
specify them one by one.

We don't have a kestrel module for jppf, but you can install it by
hand on your frontend and on the node image. Remember that the node
images are hosted on /var/lib/kestrel/images/<image_name>, and that
you can also use kestrel-images --chroot to open a terminal under the
node image.
