The Exascale Era is Upon Us: The Frontier supercomputer may be the first to reach 1,000,000,000,000,000,000 operations per second

In 2018, a new supercomputer called Summit was installed at Oak Ridge National Laboratory, in Tennessee. Its theoretical peak capacity was nearly 200 peta-flops-that's 200 thousand trillion floating-point operations per second. At the time, it was the most powerful supercomputer in the world, beating out the previous record holder, China's Sunway TaihuLight, by a comfortable margin, according to the well-known Top500 ranking of supercomputers. (Summit is currently No.2, a Japanese supercomputer called Fugaku having since overtaken it.)
