I tried adding '-mca btl ^sm -mca mpi_preconnect_all 1' to the mpirun
command line but it still fails with identical error messages.
I don't understand the issue with allocating nodes under bproc. Older
versions of OMPI have always just queried bproc for the nodes that
have permissions set so I can execute on them. I've never had to
allocate any nodes using a hostfile or any other mechanism. Are you
saying that this no longer works?

Actually, I just looked at my notes on bluesteel and see that it is an
unscheduled system - i.e., no LSF to allocate the nodes. That's a
problem
with the current code.
I assume you must be feeding it a hostfile or something?? How are you
telling mpirun which nodes to use?
Brian and I just talked about the more general bproc allocator
question and
I can commit a change later today to fix the situation for
bluesteel. Until
then, I fear that we may not run on that system, though you could
give it a
try anyway.

Oh yeah - Galen noted that you also have to do a preconnect, so
what you
need to add to your command line is:
-mca btl ^sm -mca mpi_preconnect_all 1

These all appear to be available on the nodes.
I tried a recent (today/yesterday?) svn trunk. It works but it is
very slow (I am using tcp now).

Does that mean that 1.2 does not support bproc?
