Short version: just don't list that host in the OMPI hostfile.
Long version:
In LAM, we had the constraint that you *had* to include the local
host in the hostfile that you lambooted. This was undesirable in
some cases, such as lambooting from a cluster's head node (where you
didn't want
In LAM/MPI, I can use "portal.private schedule=no" if I want to
launch a job from a specific node but not schedule it for any work. I
can't seem to find reference to an equivalent in Open MPI.
Thanks.
