    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,
