Hmm...If you are just adding tcp and keeping openib in the btl grouping, it might be possible that it is using the openib btl with the simplier commandline. Can you try the simplier commandline without tcp in the btl? Also, please show the commands you are running (working and non-working). Is there a reason why the mpirun command you are using is so complex?
