         Unfortunately “real world” reverse-mode computations frequently experience
         prohibitive space costs. To mitigate this space cost, users resort to checkpointing techniques to
         recompute, rather than save, the necessary values. Injudicious checkpointing, however, can destroy
         the favorable time performance that made reverse mode attractive in the first place. Consequently,
         reverse-mode users must spend significant amounts of development time analyzing and developing
         checkpointing schemes that complement their reverse-mode computation code. In this paper, we
         describe a particular instance of this checkpointing problem: we were using reverse-mode code
         generated by Adifor 3.0 to compute derivatives of a large computational fluid dynamics code. Our
         effort labored under the additional constraint that development time was minimal (as always, it was
         needed yesterday). Our solution was to use profiling to narrowly focus our checkpoint analysis. This
         profiling approach worked well for our problem. Furthermore, the profiling idea is sufficiently
         general that it should work well for other problems. This paper details both our results on our
         specific problem and guidelines for applying the profiling technique to other checkpoint-based
         reverse-mode development problems.",
