In fact, these superscalers are being measured by their gigawatts.
Mike CaliseGUEST
It's, wait a minute, what happened to the LINPACK data? Where's the MIPS and the FLOPs?
Elisa WoodHOST
Yep.
Mike CaliseGUEST
No, they're all measured by gigawatts.
John GustafsonGUEST
Well, I understand that you sometimes do things in making up the rules of a benchmark that don't age well, but you have to do it in order to be fair.
John GustafsonGUEST
So one of the rules of the HPL benchmark based on LINPACK is that it has to use 64-bit representation of floating point.
John GustafsonGUEST
It does not have to be a standard floating point because that benchmark has been around since the days of things like the Cray-1.
John GustafsonGUEST
I've actually written a paper about this that's being refereed right now.

John GustafsonGUEST
So I talked to the people behind the NAS parallel benchmarks that suggested that they take the FFT one and make it perfectly scalable.
John GustafsonGUEST
at least by factors of two.
John GustafsonGUEST
And they already have different sizes of it, sort of like the early days of LINPACK.
John GustafsonGUEST
There's a small, medium, large, and even larger, and even colossal.
