There is a table near the bottom of
<https://docs.einsteintoolkit.org/et-docs/Vectorisation>. Hopper and
Kraken had very similar configurations when this table was made.

At this point, vectorisation did not work with PGI, leading to
439.572s (PGI) vs. 272.993s (Intel) for the run time for this
benchmark.

Of course, this is a benchmark, and your numbers will vary.
