[FRIAM] Acronyms

[Marcus Daniels]

I don't disagree with that interpretation.   

What I meant at the time was that there is really no group of people that have a better understanding of optimizing code for, and knowledge of, microarchitectures than the people that build compilers.    People that fancy themselves experts at tuning application code performance should direct their attention to doing the Real Work of improving compilers.   I don't mean "leave it to the experts", I mean "Know what you don't know and maybe what you don't even want to know."

Exactly. Marcus said it well with something like "If the compiler doesn’t do what one expects, one probably expects wrong." We can translate that to human intercommunication. If people react in unexpected ways to what you said, perhaps change your expectations of how people will react to what you said. No sense of clarity is necessary, only repeatability and reliability. E.g. I don't particularly care whether my cat thinks that laser dot is a bug or not. What I care about is that he demonstrates his agility chasing it around the room. I seem to have developed a bit of a palsy as I age. And on days when it's bad, he *really* chases it ... like with gusto. But on days when my hand is steady, I have to fake the palsy to get him to engage completely. Why? I don't care. But I know it to be True.

This reminds me of homomorphic encryption, computing over encrypted things.
