Ah, you didn't mention the MPICH_NO_LOCAL environment in your previous 
email. In that case, the TCP communication makes sense.

The verbose output seems fine, so mpiexec and mosrun don't seem to have 
any weird interactions as I originally suspected. Btw, the above command 
is OK. You don't need to do any "preparation step" like mpd launch anymore.

Btw, does this problem not occur if you don't run it with mosrun and 
directly launch the application?
