Sorry, forgot that. So I executed
mpiexec -np 1 -d --mca pls tm --mca pls_tm_debug 1 -x
PATH --prefix /opt/openmpi hostname > openmpi1.log 2>&1
and the log is attached.

Well, all the nodes share the installation through NFS. The PATH is entered
into $HOME/.bashrc, but I also export the PATH variable as you can see above.
LD_LIBRARY_PATH is not necessary as openmpi was only built with static
libraries and libtorque.so can be found through /etc/ld.so.cache on all
nodes.

In my first two posts, all the linebreaks were missing. But if you say it was
okay for you then I won't worry any longer!
