I do know that these benchmarks can be somewhat unrealistic and the
real test is the actual application that you want to run. I already
have those timed-benchmarks for my particular computational chemistry
code and more specifically with a job representative of what we might
consider "typical" for computations on our cluster.

Yet, while speaking to larger audiences sometimes FLOPS becomes a
commonly reported and understood benchmark and hence my desire to
compute it.

That is another reason why the exact-FLOPS capacity is of not so much
interest to me as a approximate value.
