A US supercomputer is now the world's fastest.

The US has developed the world's first 'true' exascale supercomputer, fulfilling a pledge made by President Obama almost seven years ago and ushering in a new era of computing.

The world's fastest supercomputers were petascale, doing a quadrillion computations per second. Exascale has a quintillion operations per second.

The Oak Ridge National Laboratory's Frontier supercomputer is the world's first to reach 1.1 exaFLOPS (1.1 quintillion floating point operations per second, or FLOPS).

High-Performance Linpack validated the finding (HPL). Frontier can potentially execute 2 quintillion computations per second, Oak Ridge said.

standardised HPL benchmark indicates it's currently the world's fastest supercomputer.
Frontier has a precise HPL score of 1.102 exaFLOPS, making it the first real exascale machine.

Folding@home's distributed computing project passed the exascale barrier in 2020. Frontier is the first real exascale machine since computations weren't dispersed over home computers like Folding@home
