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 Brice Le 27/12/2010 02:32, S.A.Saktheesh a écrit : > 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. > > > _______________________________________________ > hwloc-users mailing list > hwloc-us...@open-mpi.org > http://www.open-mpi.org/mailman/listinfo.cgi/hwloc-users >
