What is the most powerful supercomputer in the world now?

Tianhe-2 is a supercomputer developed by China National University of Defense Technology. Its floating point operation speed is as high as 3.386 trillion times per second. It has ranked first in the list of the top 500 supercomputers in the world for four consecutive times, nearly twice as fast as the second Titan. Tianhe II adopts Intel Xeon Phi processor.

2. Titan

Titan is located in Oak Ridge National Laboratory under the US Department of Energy, which is mainly used for scientific research. It is based on Cray's XK7 system, uses Nvidia Tesla GPU and AMD Opteron CPU, and its speed reaches 1.75 trillion floating-point operations per second. By 20 18, Titan will be replaced by IBM's Summit.

3. Sequoia

This behemoth, located at Lawrence Berkeley National Laboratory in California, once topped the list of supercomputers. Its main purpose is to prolong the life of old nuclear weapons and carry out experiments related to nuclear fusion. Sequoia adopts IBM Blue Gene/Q system, with 96 racks, 98,304 computing nodes, nearly 1.6 million processor cores, and memory capacity of 1.6 Pb( 1.6 TB). Its speed can reach 17. 1 trillion floating-point operations per second.

4.k computer

K Computer is the highest ranked supercomputer in Japan. It is located at the RIKEN Institute of Advanced Computing Science in Kobe, Japan. With the floating-point operation speed of10.05 million times per second, K Computer "solves the challenges of energy, sustainability, medical care, climate change, industry and space faced by today's society".

5. increase by two

Mira is another supercomputer based on IBM Blue Gene/Q system, located in Argonne National Laboratory in Lemont, Illinois, and owned by the US Department of Energy. It is one of the most energy-efficient supercomputers, with a floating-point operation speed of 858 trillion times per second.

6. Pitts Dante

Named after Mount Daiant in the Alps, this supercomputer is located in the Swiss National Supercomputer Center. Using Cray's XC90 system, the floating-point operation speed can reach 627 trillion times per second. Piz Daint is mainly used for climate and weather modeling, and will also be applied to the research of weather physics, material science and life science.

Step 7 run away

This supercomputer built by Dell is located in Texas Advanced Computer Center, and its floating-point operation speed is 5. 1 trillion times per second. It is mainly used in medical physical structure, weather forecast and astrophysics.

8. Zhu Quinn

This supercomputer with 458,752 cores is also built on IBM Blue Gene/Q system, and its floating-point operation speed is 5 trillion times per second. Juqueen is the only supercomputer from Germany in the top ten. It is located in the research center of Iurisci, Germany, and is mainly used 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 429 trillion times per second. It is located in Lawrence Livermore Laboratory (LLNL) in California. Recently, LLNL signed new supercomputer contracts with IBM, Nvidia and Mellanox. The goal is to build a supercomputer named Sierra in 20 17, so as to improve the modeling ability of nuclear weapons and eliminate the need for underground testing.

10. strictly confidential

This is a supercomputer owned by the American government, but unlike the above supercomputer, it has no conventional code name and its location is not made public. At present, the known information is the CS-Storm system based on Cray, and the floating-point operation speed is 357 trillion times per second. At the same time, it is still the most energy-efficient supercomputer at present.
