Ah ha... this is revealing:

It seems you have a config file 
/cineca/prod/opt/compilers/openmpi/1.3.3/intel--11.1--binary/etc/openmpi-mca-params.conf
 that is excluding the TCP BTL from being used.

This config file will even prevent the TCP BTL from being shown in ompi_info -- 
remember that ompi_info shows *current* values of MCA parameters.  So you might 
want to do something like this:

    ompi_info --mca btl "" --param btl tcp

That would override the "btl" MCA parameter in your config file, allow the BTL 
TCP to be loaded by ompi_info, and therefore show you all the BTL TCP params.

Make sense?
