I suggest you look at http://bellatrix.pcl.ox.ac.uk/~ben/pbs/#lam
which patches LAM to use the PBS TM interface (via. Mpiexec) for job
startup. It's then a trivial matter of using "lamboot; mpirun ..." in
your PBS script; all cleanup should be automatic, providing lamd doesn't
die catastrophically, although you can catch even this with a cronjob
that scans /tmp/lam-*@pbs*. (PBS also needs some patching, as it doesn't
behave well with daemons started from job scripts - see mom_softkill.patch
on the same page.)

In this case, the only difference would be that you'd have to install
Mpiexec on each cluster machine.
