Subject: Re: [OMPI users] btl_tcp_if_exclude param

Ok,

this is my output:

ompi_info --param btl tcp

MCA btl: parameter "btl_base_verbose" (current value: "0", data source:
default value)
                          Verbosity level of the BTL framework
                 MCA btl: parameter "btl" (current value: "^tcp", data
source: file

[/cineca/prod/opt/compilers/openmpi/1.3.3/intel--11.1--binary/etc/openmpi-mca-params.conf])
                          Default selection set of components for the btl
framework (<none> means use all components that can be found)
                 MCA btl: parameter "btl_base_warn_component_unused"
(current value: "1", data source: default value)
                          This parameter is used to turn on warning messages
when certain NICs are not used
