You can also get info specifically on the openib params by:
ompi_info —param btl openib —level 9
Your error indicates that udcm may not be enabled on your infiniband network,
and I don’t see it listed in your IB modules - we require it for use of the
opneib btl.

Maybe here you found what need:

also you can try run gdb via mpirun to get debug info:
mpirun -np 2 xterm -e gdb ./your_program

Sorry, I attached the wrong output of ompi_info... this one is the right
one.
I also forgot to add the configure-line:
> configure --prefix=/sw/mpi/openmpi/1.8.5-gnu_sschu/
> --enable-orterun-prefix-by-default --enable-mpi-thread-multiple
> --with-verbs --with-tm=/sw/tools/torque/5.1.0/
