Interesting that their GraySort result is CPU bound while they are using 3x more CPUs than the record holder from ten years ago.

  How can you determine that it CPU bound from the attached charts?

    Because it hits a read peak in the first wave and never hits it again.

      Could be many other reasons, giving it more CPU won't necessarily increase the read rate.
