Exaflops/s : WTF are Exaflop accelerating?
I’ll help with a layman explanation in addition to what op already defined.
Teraflops is a measure of raw compute power often used to measure GPUs(but isn’t really accurate to use to compare 2 different kinds, but that’s a whole nother conversation). Exaflops are a million times more than teraflops.
Right, but flops is floating point operations per second. Adding another /s makes it acceleration.
Where is the other s?
Exaflop is 1 quintillion flops (floating point math operations in a second.). Yes, probably can run DOOM.
That’s the joke. The table has Exaflops/s => Exaflop /s2 => acceleration. Ah, no it doesn’t, it has Exaflop/s rather that the normal Exaflops. My bad. Funny how you see what you expect to, no?
Since this article is very light on details-
It’s using Huawei LX2 ARMv9 cores, 304 cores @1.5ghz 690W (with 1x? SVE2 unit and an SME unit, nice) with two seats per node, originally it was to have 20,480 nodes in 90 cabinets for 40,960 CPUs (12,451,840 cores…) but the TOP500 listing has more cores (13,789,440 - 4,400 more) than some of the original documentation, so they must have added a few cabinets.
Pretty neat, brute-forcing it with CPUs makes for an infinitely more useful machine than GPU compute, despite the higher power cost. (42MW vs. 29MW for El Capitan)
