I think that in pure OpenMPI environment (without any resorce manager) you should be able to run applications like this:
mpirun -np 2 mpi_executable
mpirun -np 4 -machinefile machines.list mpi_executable
where machines.list contains a list of your computers identified by their host names.
The former command should run the program locally on 2 processors/cores, the latter
one on those specified in the list.
