Top 10 Supercomputers in the world.

Supercomputer as the name suggests is a powerful computer which handles high level of work. Supercomputers are used in a variety of fields like climate research, quantum mechanics, weather forecasting, molecular study and others. The first supercomputer was a joint venture between the Manchester University and Ferranti, developed by Control Data Corporation and was named Atlas. This supercomputer was designed by Seymour Cray, who went on to establish his own company Cray Research and develop some of the fastest and powerful supercomputers of that time. The performance and capacity of a supercomputer can be measured by using floating point operations per second or FLOPS.

Here is a list of the top 10 supercomputers in the world.

Sunway TaihuLight 

This supercomputer located in Wuxi, China is the world’s most powerful supercomputer as of November 2016. This supercomputer was constructed entirely using processors made in China. The supercomputer has Sunway MPP and Sunway SW26010 260C 1.45 GHz. It houses 10,649,600 cores and has 93 petaflops per second and can reach up to 125 petaflops/s. This has been rightly called the Zeus of supercomputers.

Tianhe 2

The second most powerful supercomputer also belongs to China. Located in Guangzhou, China, this supercomputer uses the Intel Xeon E5-2692v2 processor and has 3.1 million cores. It scores 33.8 petaflops/s and can reach up to 54.9 petaflops/s. Also called the Milky Way 2. It was built by the Chinese National University of Defense Technology.

The Piz Daint is located at the Swiss National Supercomputing Center. This supercomputer used to run on the Cray XC30 but after its upgrade to Cray XC40/XC50 it has become Europe’s most powerful supercomputer. It operates on the Cray Linux Environment processor and has recorded 19.59 petaflops per second.


Spurce: Oak Ridge Leadership Computing Facility

This US based supercomputer is located in the Oak Ridge National Laboratory in Tennessee. Built by Cray Inc. this supercomputer uses AMD opteron CPU’s and NVidia Tesla GPUs. It houses 560,640 cores and has a performance of 17.5 petaflops per second. This used to be the fastest and most powerful supercomputer until the Tianhe 2 came along.


Located in United States, California this IBM built supercomputer was built for US National Nuclear Security Administration. Later it was transferred to the Lawrence Livermore National Library. This supercomputer performs up to 17.173 petaflops per second.

Cori Supercomputer

This was named after United States’ very first female Nobel laureate in Science Gerty Cori. This Cray XC 40 supercomputer performs 14.014 petaflops per second with 622,366 cores. This supercomputer was built for the National Energy Research Scientific Computing Center in the US.


Located in Japan this Fujitsu built supercomputer operates on the Intel Xeon Phi processor. With performance of 13.554 petaflops/s this supercomputer takes the 7th position in the top 10 list.

K Computer

Located in the Advanced Institute of Computational Science in Japan this supercomputer is built by Fujitsu. It houses 705,024 cores and performance of 10.51 petaflops/s.


This supercomputer in the US is built by IBM for the Argonne National Laboratory. It has a performance of 8.586 petaflops/s with 786,432 cores.

Trinity Supercomputer

This Cray built supercomputer in the United States is used by National Nuclear Security Administration. It has a performance of 8.1 petaflops per sec with cores up to 301,056.
