Fastest Super Computers

World's Fastest Super Computers

the world's most powerful supercomputer for the first time since 2012, but China remains the global supercomputing leader. 

In the June 2018 edition of the TOP7500 rankings, China accounted for 206 of the 500 fastest machines, while the USA's total of 124 is its lowest since the list was established 25 years ago.

Japan came in third with 36 supercomputers on the list, while the UK climbed to fourth after expanding its arsenal from 15 systems in November 2017 to 22 today. Germany with 21 and France completed the pack of supercomputing superpowers.

1. IBM Summit

The IBM Summit at the Oak Ridge National Laboratory is capable of making 200 quadrillion calculations per second, which makes it more than 1 million times more powerful than the world's fastest laptop.

Summit is also 60 percent faster than the TaihuLight that previously topped the rankings, ending a five-year spell in which China was home to the world's most powerful supercomputer. Summit will be used to accelerate our understanding of diseases and to identify next-generation materials.

Top speed: 122.3 petaflops

Total cores: 2,282,544

2. Titan – United States

The Titan computer is a Cray XK7 system used by the United States Department of Energy at their Oak Ridge National Laboratory. The former top-ranked Jaguar supercomputer was upgraded in 2012 to become the then most powerful computer (until the Tianhe machine overtook it).

The system performs at 17.59 Pflop/s using 261,632 NVIDIA K20x cores.

3. Sequoia – United States 

The Sequoia computer is based on the now unsupported IBM BlueGene framework. It has been used to make key advances in climate, astronomy and energy application areas.

Located in California’s Lawrence Livermore National Laboratory, the Sequoia platform has achieved 17.17 Pflop/s and uses 1,572,864 cores.

4. K Computer – Japan

The K computer was manufactured by Fujitsu at the RIKEN Advanced Institute for Computational Science (AICS) in Kobe, Japan.

This system hit 10.51 Pflop/s and uses 705,024 SPARC64 processing cores.

5. Mira – Unites States

Also built around the BlueGene architecture, the Mira is one of the older computers on the list. Primarily used by the Unites States Department of Energy (and now housed at the Argonne National Laboratory outside Chicago), it is being succeeded by the upcoming Aurora supercomputer.

The Mira computer has peaked at 8.59 Pflop/s and uses 786,432 cores.

6. Piz Daint – Switzerland

The Piz Daint, a Cray XC30 system, is the most powerful computer in Europe. It’s installed at the Swiss National Supercomputing Centre (CSCS) in Lugano, Switzerland.

Piz Daint achieved 6.27 Pflop/s on the Linpack benchmark, using 73,808 NVIDIA K20x accelerator cores.
