Actually, Fortran was designed to be optimized, and IBM's first
compiler was an optimizing compiler. A compiler/language co-design, if
you will. It wasn't very sophisticated compared to today's compilers,
but it was extremely sophisticated for its era.

As for Doug's comments about Summit and Sierra being co-designs, I
think that's great. InfiniPath's design was focused on building the
smallest possible chip that did what MPI needed. I've always wondered
what would have happened to Myricom had they redesigned their chip to
do exactly what their MX software interface needed.
