Hello Saktheesh,

NICs do not appear in the topology yet. This is under development in the libpci branch. You can take a look at
    https://svn.open-mpi.org/svn/hwloc/branches/libpci
and tell us what you think of the interface. If you're talking about infiniband NICs, hwloc/openfabrics-verbs.h might help you in the meantime.

By the way, what do you mean by "distance" ? There is also some work about exposing NUMA distances (and more) in the API, see
    https://svn.open-mpi.org/svn/hwloc/branches/distances

Hi all,

I am trying to identify NIC in a topology with the help of HWLOC.
Is NIC considered as a object in the topology.I am able to find other objects in the mailing list such as CORE,PU,CACHE etc.

I am trying to find this because I am interested in finding distance between a Socket and a NIC in a given topology.

With kind regards,
Saktheesh.
