mpirun / mpiexec can launch applications on any node, regardless of the
"schedule" attribute. So you can do something like:
mpiexec n0 master : -np 4 slave
Which will run "master" on n0 (regardless of its schedule attribute)
and then use default scheduling for the slaves (i.e., not use n0).
See the mpirun(1) man page for more details.
