You can issue multiple mpirun's simultaneously to do what you want. For
example:
Lamboot [your_hostfile]
mpirun N -np 4 a.out &
mpirun N -np 4 b.out &
mpirun N -np 4 c.out &
mpirun N -np 4 d.out &
The "N" means that it will launch one process per node.
Note that "lamclean" will kill all processes in the entire universe. Hence,
running lamclean will kill all 16 processes.
