Wonderful, thank you! I've attached what it shows on our
SGI Altix XE270 management node (with a dual ported IB card).

Does the information occur to the right of the socket with
the closest distance to the devices ?

Well at the moment that looks rather nice to me, though it
would indeed be good to see GPUs labelled to - though I've
seen your comment in the source saying:

/* FIXME: what about gpus? could try class "drm", but
   proprietary drivers won't appear there */

I don't have any boxes at all with GPUs in them, so I'm not
sure what to suggest there. :-(

cheers,
Chris
