For TCP you can get the list of available MCA parameters using
"ompi_info --param btl tcp". The one involved in selecting the
network are:
btl_tcp_if_include
btl_tcp_if_exclude
You just have to set one of them as they are exclusive. So if you
want to select the second network interface (let say it is named
eth1) you have to add in the mca-params.conf file the following line:
bl_tcp_if_include=eth1
FWIW, I added a bunch of "MPI Tuning:" sections to the FAQ today -- I
added all this information into the "MPI Tuning:TCP" section:
