    I have created simple fink ( packaging
for open-mpi v1.1 on MacOS X. The packaging builds open-mpi with its
default settings in configure and appears to pass all of its make check
without problems. However, the lack of clear documentation for open-mpi
still is a problem. I seem able to manually run the test programs from
the open-mpi distribution using...

mdrun -np 2 ...

after starting the orted daemon with....

orted --seed --persistent --scope public

I can see both cpus spike when I do the mdrun's so I think
that works. However, I can't figure how the proper way to
monitor the status of the available nodes. Specifically,
what is the equivalent to the lamnodes program in open-mpi?
Also, is there a simple test program that runs for a significant
period of time that I can use to test the different options to
monitor and control the open-mpi jobs that are running under
orted? Thanks in advance for any clarifications.
ps I assume that at v1.1, open-mpi is considered to be a usable
replacement for lam? Certainly, gromacs 3.3.1 seems to compile
its mpi support against open-mpi.
