Actually, this was also the subject of another email thread on the
user list earlier today. The user noted that we had lost an important
line in our Makefile.am for the tm plm module, and that this was the
root cause of the problems you and others have been seeing. We don't
see it here because we always configure as shown below.
This has been fixed in the upcoming 1.3.1 release.
In the meantime, if you configure with --enable-static --enable-
shared, the required library will be linked into OMPI and will be
available.
Sorry for the problem.

Hey,
I've just installed OpenMPI 1.3 on our cluster, and am getting
this issue on jobs > 1 node.
mpiexec: symbol lookup error: /usr/local/openmpi/1.3-pgi/lib/
openmpi/mca_plm_tm.so: undefined symbol: tm_init
As reported before, I saw someone saying that they solved this
with: --enable-mca-static=plm:tm
A new install using this configure option does work for me, but
only for code recompiled with this new mpicc. Existing code
doesn't spawn properly.
No, it won't since the static libraries for tm plm component
weren't linked directly into the code.
Ahh, didn't think of that.
As such, I'd much rather get the existing install working again.
It was suggested that I need the torque libraries on the compute
nodes, which they are. However adding them to ld.so.conf has not
solved this, so I'm not sure what more needs to be done to solve
this without recompiling openmpi.
I'm not sure what you mean by adding them to ld.so.conf. What you
need to do is install the torque libraries on the compute node in
the same absolute path where they reside on the node where OMPI was
built. OMPI points the executable to look for that location.
Other than that, there shouldn't be a problem.
This is what confuses me.
We export /usr/local from the mgt node to all compute nodes.
Both torque and openmpi are installed to /usr/local.
So why are we hitting this issue?
cheers,
