Whoops, should have thought of that. Note the output is formatted for
80 columns, so it may look a little dodgy in 72 columns - attached it
instead.
Sorry it's a bit large, but needed to show the difference, but feel free
to clip out the middle CPUs or something. This is from a 4-node 8-cpu
box.
Cheers,
