U.S Get World's Fastest Super Computer By 2021

As you know from the tittle that U.S Get the super computer which can do 1billion in 1 sec.

The Aurora will be the first exaflop computer in the US for sure, but may not necessarily be the first in the world. China is also trying to build a similar system by 2020, and they'll likely achieve it in that timeline too.
The two companies had signed go build the super computer for America. The first is Aurora which is famous for his monstrous computers

For those of you a little lost, an exaflop is a thousand petaflops which means the supercomputer will be able to perform one quintillion calculations per second. To put that into perspective, an average desktop these days is capable of about a hundred gigaflops. A thousand gigaflops makes one teraflop, and 1,000 teraflops make a petaflop.

Even some of the most powerful supercomputers in the world today are only capable of petaflops. So what did the Argonne Lab need such a powerful computer for? As it turns out, a lot. They plan to use the supercomputer for everything from researching renewable energy, to planetary science, to genetics, to climate change, and much more.
