Just to further show my confusion (since I wrote much of the TM support):
If you get an interactive allocation and then type "mpirun ....", mpirun will execute on the node upon which you are sitting. Jeff's statement is -only- true if you "qsub" the job - i.e., you run it in batch mode.
From your prior notes, I was under the impression you were running interactively. If this is true, then you only need OMPI to be built with TM support on the node which you are interactively working on.
If you are running it in batch mode, then Jeff is correct - you will need OMPI built with TM support on all nodes since you (in general) cannot know which node PBS will launch you on.
Hope that is clear
