Yes, it's right! Now i can see btl_tcp_if_include flag:
MCA btl: parameter "btl_tcp_if_include" (current value: <none>, data source: default value) MCA btl: parameter "btl_tcp_if_exclude" (current value: "eth0,ib0,ib1", data source: file [/cineca/prod/opt/compilers/openmpi/1.3.3/intel--11.1--binary/etc/openmpi-mca-params.conf]) My actual configuration is: btl = ^tcp btl_tcp_if_exclude = eth0,ib0,ib1 oob_tcp_include = eth1,lo But is it right?
