That would be most useful, possibly avoiding a lot of wasted resources.

So it is = useful to understand the parallel speedups of a code one has
already decided to use, but it is misleading to = compare parallel
speedups of different codes = without looking at the actual time to
solution = for representative calculations (being careful to compare
