What's exascale?

in very simple terms computing power of supercomputers is often defined by FLOPS (floating point operations per second) because a lot of simulations require just that.

1 FLOP would be 1 operation per second. And just like with storage you can pre-pend it with kilo, mega, giga, ...

So 1 kiloflop would be 1000 operations per second, 1 megaflop would be 1000 kiloflops, ... etc.

Then mega -> giga -> tera -> peta -> exa. So yeah, we're finally breaching exaFlops of computing power which is big. Even just a couple of years ago we were barely reaching 100 PFLOPS and now we're already aiming beyond 10 EFLOPS. We're talking absolutely INSANE levels of computing power

Exascale is a Quintillion Floating Point Operations per second, or: 1,000,000,000,000,000,000 FLOPS. That is an absolutely enormous number
