has anyone done work with hwloc on scalemp systems? They provide
their own tool numabind, but we are looking for a more generic
solution to process placement and control that works well inside our
MPI library (openMPI in most cases).
Any input on this would be great!

Not here, but I guess something could be done, yes.

Because it doesn't know what these actually are, just that there is some
distance being involved :)
