    <p>I'm not going to dispute your claims, but I think you're probably
      a statistical anomaly in this regard. I'm guessing your code isn't
      that old, so it was built using current 'best practices' for
      parallelization (loop independence, data parallelism, overlapping
      communication and computation, etc) for the get-go, or was at
      least kept 'modern'  which made it easy for the compilers to
      optimize for the Phis. <br>

    Can you comment on this? <br>
