What is the most powerful supercomputer in the world now?

1. Tianhe-2

Tianhe-2 is a supercomputer developed by the National University of Defense Technology of China. Its floating-point operation speed is as high as 33.86 petaflops per second. It has been continuously It has ranked first in the world's TOP500 supercomputers list for four consecutive times, and is nearly twice as fast as the second-place "Titan". Tianhe-2 uses Intel Xeon Phi processors.

2. Titan

Titan is located at the Oak Ridge National Laboratory under the U.S. Department of Energy and is mainly used for scientific research. It is built on Cray's XK7 system, using Nvidia Tesla GPU and AMD Opteron CPU, with a speed of 17.5 petaflops. By 2018, Titan will be replaced by IBM's Summit.

3.Sequoia

This behemoth located at the Lawrence Berkeley National Laboratory in California once ranked first among supercomputers. Its main purpose is to extend the life of old nuclear weapons and expand Experiments related to nuclear fusion. Sequoia uses the IBM Blue Gene/Q system, which has 96 racks, 98,304 computing nodes, nearly 1.6 million processor cores, and a memory capacity of 1.6PB (1,600TB). It is capable of 17.1 petaflops.

4.K Computer

K Computer is the highest-ranking supercomputer in Japan. It is located at the RIKEN Institute for Advanced Computing Science in Kobe, Japan, with its 105 million floating-point operations per second. speed to “solve the energy, sustainability, healthcare, climate change, industrial and space challenges facing society today.”

5. Mira

Mira is another supercomputer based on the IBM Blue Gene/Q system. It is located at the Argonne National Laboratory in Lemont, Illinois, and is funded by the U.S. Energy All. It is one of the most energy-efficient supercomputers, capable of 8.58 petaflops of floating-point operations per second.

6.Piz Daint

This supercomputer is named after the Daint peak in the Alps. It is located at the Swiss National Supercomputer Center and uses Cray's XC90 system. , the floating point operation speed can reach 6.27 quadrillion times per second. The main use of Piz Daint is climate and weather modeling, but it will also be used in research in weather physics, materials science and life sciences.

7. Stampede

This supercomputer built by Dell is located at the Texas Advanced Computing Center. Its floating point operation speed is 5.1 petaflops per second. It is mainly used in pharmaceutical physics structures, weather forecasting and astrophysics.

8.Juqueen

This 458,752-core supercomputer is also built on the IBM Blue Gene/Q system and has a floating-point operation speed of 5 petaflops per second. . Juqueen is the only supercomputer from Germany among the top ten. It is located at the Urich Research Center in Germany and is mainly used for research in neuroscience, computational biology, climate research and quantum physics.

9.Vulcan

Like Juqueen, this supercomputer also uses the IBM Blue Gene/Q system, with a floating-point operation speed of 4.29 petaflops per second. It is located at Lawrence Livermore Laboratory (LLNL) in California. Recently, LLNL signed a new supercomputer contract with IBM, Nvidia and Mellanox. The goal is to build a supercomputer called Sierra in 2017 to improve the ability to model nuclear weapons and eliminate the need for underground testing.

10. Top Secret

This is a supercomputer owned by the US government, but unlike the above supercomputers, it does not have a regular code name and its location is not the same. Not disclosed to the public. What is currently known is that it is based on Cray's CS-Storm system and has a speed of 3.57 petaflops. At the same time, it is the most energy-efficient supercomputer currently available.
