Hi, I don't know if there is a way to do it in configure, but after installing you can go into the $prefix/lib/openmpi directory and delete mca_btl_tcp.*
This will remove the tcp component and thus users will not be able to use it. Note that you must NOT delete the mca_oob_tcp.* files, as these are used for our internal administrative messaging and we currently require it to be there.
