An anecdote in a similar vein:
I was involved in writing (Fortran) code for Crays in the 90s. For the T3D, we speeded up the code with the usual set of tricks -- loop unrolling, array padding and so on. With the later T3E, it turned out that not only could the compiler now do all that, but that code hand-optimised in this way performed worse.
- kenjackson 16y agoHeh, we may know each other. I also developed code on the T3D and T3E. I figure can't be too many people in the world that developed for both. I still have the big gray Cray binders with the documentation laying around somewhere.
