Hmmm...well, it looks from your original error message that Rmpi/snow is using
a single "master" process and then comm_spawn'ing a whole bunch of "workers". I
tried replicating that on a slurm machine by having a single master comm_spawn
a whole bunch of processes, and that worked fine. Of cours
Ah - okay, my misunderstanding. Would you be willing to give the trunk a try?
It might help to know if the problem is solely in 1.6, or continues.

Guess I'm confused - your original note indicated that something had changed in
Rmpi that broke things. Are you now saying it was something in OMPI?

Ok will see, Rmpi we had working with 1.4 and has not been updated after 2010,
this this kinda stinks.
I will keep digging into it thanks for the help.

Ralph,
Rmpi wraps everything up, so I tried setting them with
export OMPI_plm_base_verbose=5
export OMPI_dpm_base_verbose=5
and I get no extra messages even on helloworld example simple MPI-1.0 code.

Well, it looks like comm_spawn is working on 1.6. Afraid I don't know enough
about Rmpi/snow to advise on what changed, but you could add some debug params
to get an idea of where the problem is occurring:
-mca plm_base_verbose 5 -mca dpm_base_verbose 5
should tell you from an OMPI perspective.
Weird - looks like it has done a comm_spawn and having trouble connecting
between the jobs. I can check the basic code and make sure it is working - I
seem to recall someone else recently talking about Rmpi changes causing
problems (different ones than this, IIRC), so you might want to search ou
I have ran into a problem using Rmpi with OpenMPI (trying to get snow running).
I built OpenMPI following another post where I built static:
./configure --prefix=$INSTALL/gcc-4.4.6-static
--mandir=$INSTALL/gcc-4.4.6-static/man --with-tm=/usr/local/torque/
--with-openib --with-psm --enable-stati
