I added a new framework to Open MPI called carto. You
can brows the code in: http://svn.open-mpi.org/svn/ompi/tmp-public/carto/.
There are some explanations about the carto framework
in the project wiki: https://svn.open-mpi.org/trac/ompi/wiki/OnHostTopologyDescription
and you can read the attached doc.
The carto framework can’t do any damage because
no one calls it. So, if there are no objections, I would like to merge the
carto framework to the trunk.
