That seems like way too strong a statement to me. Firstly, top 500
gives you something like an estimate upper bound on the performance of
almost any code you might write. It tells you how much you are giving
up by not making your code more linpack-like.

Secondly, some code, eg simple computer vision algorithms, don't look
that different from linpack, and might scale just as well. It seems
wrong to call those algorithms as having absolutely nothing to do with
