fastest supercomputers

Supercomputers are the high tech computers that are built to perform several quick operations. Many countries have worked on building supercomputers. Developed countries such as China and Japan always compete with each other in building the fastest supercomputer ever. What makes supercomputers special is that they perform millions of functions at one go. Supercomputers made their debut for the first time in the 1960s and have changed a lot since then. Very few countries own supercomputers with China topping the list with 229 supercomputers. Here’s the list of some of the fastest supercomputers in the world.


Currently being the fastest supercomputer in the world, Fugaku was developed by Japan. The speed of the supercomputers is measured with FLOPS (Floating Point Operations per Second). Fugaku works at an unimaginable speed of 415.5 petaFLOPS per second. This is the first of its kind of the new generation of supercomputers. Fugaku is located at RIKEN centre for Computational Sciences in Kobe, Japan. Fugaku is termed to be useful for various social and scientific issues. With the supercomputer already commenced it will officially be started to use in 2021.


The supercomputer that held first place for more than 2 years is Summit. A supercomputer developed by the United States, it is plugged in at Oak Ridge National Laboratory. Summit was once considered a powerful supercomputer with the speed of 148.6 petaFLOPS per second. Summit was always used for health uses to find a cure for diseases and other health issues. Currently, Summit is used to find a cure and discover treatments for coronavirus.


Another super product of the United States is the supercomputer, Sierra. Sierra was designed to keep up with the US government’s ambitious nuclear projects. With the speed of 94.6 petaFLOPS per second, Sierra is the world’s third-fastest supercomputer. Sierra is designed by Lawrence Livermore National Laboratory using some of the powerful CPUs by IBM and GPUs by Nvidia.

SunWay Taihu Light

Being China’s fastest supercomputer and also the world’s fastest supercomputer is SunWay Taihu Light. It was leading the charts when it made its debut in 2016 before the US’s Sierra and Summit. SunWay Taihu Light runs at the speed of 93.01 petaFLOPS per second and is made of over 10,649,000 cores. This supercomputer was made in the National Supercomputing Centre in Wuxi, China. It is being very useful in reading the weather and climate. Currently, weather forecasting is the primary use of SunWay Taihu Light.

Tianhe -2 or Milkyway -2

Milkyway -2 was introduced by China when they were ruling the world of supercomputers. Since making its debut in 2013, Milkyway -2 held the first place before being overtaken by China’s other supercomputer. With a speed of 61.4 petaFLOPS, Milkyway -2 is currently the 5th fastest supercomputer. The National University of Defence Technology developed Tianhe -2 and is used primarily for defence purposes. The uses of Tianhe -2 is kept secret and it is known to run some of the most secret and sophisticated files of the Chinese government.
