"Frontier, the name of the massive machine at Oak Ridge National Laboratory, was declared on Monday to be the first to demonstrate performance of one quintillion operations per second — a billion billion calculations — in a set of standard tests used by researchers to rank supercomputers. The U.S. Department of Energy several years ago pledged $1.8 billion to build three systems with that “exascale” performance, as scientists call it. "

"The system, built by Hewlett Packard Enterprise uses two kinds of chips from Advanced Micro Devices..."
...
"the system, composed of 74 cabinets that each weighs 8,000 pounds...

IBM's system at Oak Ridge held the #1 spot in 2019.

"Megaflops, gigaflops. teraflops, petaflops - A gigaflop is a billion floating-point operations per second, a teraflop is one trillion, and a petaflop is a quadrillion. "

"This new exascale technology integrates electrical and optical devices on the same piece of silicon, enabling computer chips to communicate using pulses of light—instead of electrical signals—resulting in smaller, faster and more power-efficient chips than is possible with conventional technologies."

Thus we now have exaflops.

Dang!
