The most powerful supercomputers in the world

• Sequoia - Blue Gene / Q

Location: United States
Productivity: 17.1 petaflops
Theoretical maximum of productivity: 20.13 petaflops
Power: 7.8 MW

The most powerful of the four supercomputers of the Blue Gene / Q family, ranked in the top ten ranking, is located in the US at the Livermore National Laboratory. IBM developed Sequoia for the National Nuclear Security Administration (NNSA), which required a high-performance computer for a very specific purpose - modeling nuclear explosions.

• Titan - Cray XK7

Location: United States
Productivity: 17.59 petaflops
Theoretical maximum of production: 27.11 petaflops
Power: 8.2 MW

Despite its computational power and impressive dimensions (404 square meters), Titan did not last long on the pedestal. Already six months after the triumph in November 2012, the pride of Americans in the field of high-performance computing suddenly pushed the native from the East, unprecedentedly overtaking the previous leaders of the rating.

• Tianhe-2 / Milky Way-2

Location: China
Productivity: 33.86 petaflops
Theoretical maximum productivity: 54.9 petaflops
Power: 17.6 MW

Since its first launch, Tianhe-2, or Milky Way-2, has been the Top-500 leader for nearly two years now. This monster is almost twice as high as in performance No. 2 in the ranking - the TITAN supercomputer.

Developed by the Defense Science and Technology University of the People's Liberation Army of the PRC and Inspur "Tianhe-2" consists of 16,000 nodes with a total number of nuclei of 3.12 million. Operative memory of the whole of this colossal construction, occupying 720 square meters, is 1.4 petabytes, and the storage device - 12.4 petabytes.
