10 Fastest Supercomputers In The World

#3 Sequioa

Country: U.S.

Site: DOE/NNSA/LLNL

Manufacturer: IBM

Cores: 1,572,864

Linpack Performance (Rmax): 17,173.2 TFlop/s

Theoretical Peak (Rpeak): 20,132.7 TFlop/s

Power: 7,890.00 kW

Memory: 1,572,864 GB

Interconnect: Custom Interconnect

Operating System: LinuxIBM Sequioa is constructed by IBM for the National Nuclear Security Administration as part of the Advanced Simulation and Computing Program (ASC). It was delivered to the Lawrence Livermore National Laboratory (LLNL) in 2011 and was fully deployed in June 2012.

Sequoia will be used primarily for nuclear weapons simulation, and also plays important role for scientific purposes such as astronomy, energy, study of the human genome, and climate change.

#2 Titan

Country: U.S.

Site: DOE/SC/Oak Ridge National Laboratory

Manufacturer: Cray Inc.

Cores: 560,640

Linpack Performance (Rmax): 17,590.0 TFlop/s

Theoretical Peak (Rpeak): 27,112.5 TFlop/s

Power: 8,209.00 kW

Memory: 710,144 GB

Interconnect: Cray Gemini interconnect

Operating System: Cray Linux EnvironmentTitan is a supercomputer built by Cray at Oak Ridge National Laboratory for use in a variety of science projects. Titan is an upgrade of Jaguar, a previous supercomputer at Oak Ridge that uses graphics processing units (GPUs) in addition to conventional central processing units (CPUs). It is the first such hybrid to perform over 10 petaFLOPS.

Titan will use its extraordinary computing power for study alternative and efficient energy, efficient engines, climate change, and identifying new materials.

#1 Tianhe-2

Country: China

Site: National University of Defense Technology (NUDT)

Manufacturer: NUDT

Cores: 3,120,000

Linpack Performance (Rmax): 33,862.7 TFlop/s

Theoretical Peak (Rpeak): 54,902.4 TFlop/s

Power: 17,808.00 kW

Memory: 1,024,000 GB

Interconnect: TH Express-2

Operating System: Kylin Linux

Compiler: ICC

Math Library: Intel MKL-11.0.0

MPI: MPICH2 with a customized GLEX channel

Tianhe-2 ("Milky Way 2") is a 33.86 petaflops supercomputer located in Guangzhou, China. It was developed by the team of 1300 scientists and engineers. In June 2013, Tianhe-2 topped the TOP500 list of fastest supercomputers in the world. The computer beat out second place finisher Titan by nearly a 2-to-1 margin.
