I can only urge to resist the tempation to leave ompi for lam. Check out the
ompi docs; I have been lurking on their lists since we revitalised Debian's
(then dead) open mpi packages.  It is excellent code, the team (from the
likes of llnl.gov, cisco, hp and a few universities) is first rate and very
committed. Also, as noted, lam is dead and will not be developed further.

Plus, under Debian you get the slurm batch process managing tools that need
ompi and won't work with lam.

My $0.02, and your call.   This is off-topic now for r-sig-debian and I'll
stop here.

Enjoy, Dirk
