You actually probably want:
ompi_info | grep btl
That will show you the names and versions of the "btl" plugins that are
available on your system. For example, this is what I have on my system from a
development build (this is on the Open MPI development head; not in a release):
----
$ ompi_info | grep btl
MCA btl: ofi (MCA v2.1.0, API v3.1.0, Component v4.1.0)
MCA btl: self (MCA v2.1.0, API v3.1.0, Component v4.1.0)
MCA btl: vader (MCA v2.1.0, API v3.1.0, Component v4.1.0)
MCA btl: openib (MCA v2.1.0, API v3.1.0, Component v4.1.0)
MCA btl: usnic (MCA v2.1.0, API v3.1.0, Component v4.1.0)
MCA btl: tcp (MCA v2.1.0, API v3.1.0, Component v4.1.0)
MCA fbtl: posix (MCA v2.1.0, API v2.0.0, Component v4.1.0)
----
You can get fancy and get parsable output, too:
----
$ ompi_info --parsable | grep :btl: | grep component
mca:btl:ofi:version:"component:4.1.0"
mca:btl:self:version:"component:4.1.0"
mca:btl:vader:version:"component:4.1.0"
mca:btl:openib:version:"component:4.1.0"
mca:btl:template:version:"component:4.1.0"
mca:btl:usnic:version:"component:4.1.0"
mca:btl:tcp:version:"component:4.1.0"
