World’s most strongest supercomputer & World’s most powerful supercomputer

8. Fujitsu’s K

Fujitu’s K computer was the first supercomputer to have ever broken the ten petaFLOPS barrier in November 2011. The K in its name refers to the Japanese word “kei,” or 10 quadrillion—a reference to the number of FLOPS. To compute at this level, the K combines the power of 80,000 separate CPUs through specialized connectors designed to transmit data at high speeds. A water-cooling system makes individual CPU cores less likely to overheat.

7. Oakforest-PACS

Resulting from a collaboration between the University of Tokyo, the University of Tsukuba and Fujistu Limited, the supercomputer dubbed Oakforest-PACS broke the 25 petaFLOP barrier thanks to Intel’s latest generation of Xeon Phi processors, making it the fastest supercomputer in Japan. The system is made up of 8,208 computational nodes, and is used for furthering computational science research and teaching young researchers how to conduct high-performance computing.

6. Cori (NERSC)

The National Energy Research Scientific Computing Center near Oakland, California named its newest supercomputer creation “Cori,” after Gerty Cori, the first American woman to win a Nobel Prize. The system is a Cray XC40, manufactured by the company responsible for major breakthroughs in supercomputer performance during the 1970s. Cori can theoretically achieve a processing speed of 29.1 petaFLOPS. It achieves this through the use of Haswell architecture Intel Xeon and Xeon Phi processors.

5. Sequoia

The Sequoia is a supercomputer built to measure the risks of nuclear warfare by making advanced weapons science calculations. It’s owned by the Lawrence Livermore National Laboratory in California. With 98,304 nodes, it’s ranked as the fifth most powerful supercomputer on the planet. According to the Linpack benchmark, it has a speed of 17.2 petaFLOPS.

4. Titan

Perhaps one of the best-known supercomputers in the Western world, Titan at Tennessee’s Oak Ridge National Laboratory was the fastest supercomputer on the planet until the Tianhe-2 (below) jockeyed it out of first place in 2013. Titan is the first supercomputer to combine AMD Opteron CPUs and NVIDIA Tesla GPUs, bringing its total theoretical peak output to 27 petaFLOPS (Linpack approximates its output at 17.6). This kind of power enables researchers to perform the complex simulations needed in climate science, astrophysics, and molecular physics.

3. Tianhe-2

The Tianhe-2, also known as MILKYWAY-2, is a supercomputer developed by China’s National University of Defense Technology. It became the world’s fastest supercomputer in June 2013 with a peak performance of 33.86 petaFLOPS (although peak theoretical performance could be much higher), though it has slid down to third place in the years since. 16,000 computer nodes, made up of Intel Ivy Bridge and Xeon Phi processors, enable simulations of government security applications. It also serves as an open research platform for scientists in southern China.

2. Piz Daint (2017)

In late 2016, the Piz Daint supercomputer in Lugano, Switzerland gained a huge hardware upgrade. That new power tripled its computing performance and brought its theoretical peak performance up to 19.6 petaFLOPS (their own measurements pin it currently at 25.3), making it the fastest supercomputer outside Asia. Named after a mountain in the Swiss Alps, the Piz Daint also creates advanced visualizations and high-resolution imaging simulations. It will soon provide processing power to the Large Hadron Collider at CERN, helping it analyze huge amounts of data.

1. Sunway TaihuLight

Currently ranked as the fastest supercomputer in the world, the Sunway TaihuLight supercomputer measures in at 125 petaFLOPS (theoretical peak)—five times as fast as the supercomputer in second place. Housed in the National Supercomputing Center in Wuxi, it is comprised of 10.6 million cores and is being used for climate research, earth systems modeling and data analytics. On top of being the fastest supercomputer in the world, the Sunway TaihuLight is currently ranked as the fourth most energy-efficient one as well, requiring substantially fewer megawatts per megaFLOPS.
