A supercomputer has a high level of performance as compared to a general-purpose computer.

The performance of a supercomputer is commonly measured in floating-point operations per second (FLOPS).

Since November 2017, all of the world's fastest 500 supercomputers run Linux-based operating systems.

Supercomputers play an important role in the field of computational science.

It is used for a wide range of computationally intensive tasks in various fields, including ... 

quantum mechanics, weather forecasting, climate research, oil and gas exploration, molecular modeling.

China currently dominates the list with 188 supercomputers.

Since June 2020, the Japanese Fugaku is the world's most powerful supercomputer.

Fugaku is a petascale supercomputer at the Riken Center for Computational Science in Kobe, Japan.

It started development in 2014 as the successor to the K computer, and started operating in 2021.
