Every six months, the Top500 Organization ranks the five hundred 
fastest supercomputers in the world. And for the fourth consecutive list, China’s Tianhe-2 is on top, performing at 33.86 petaflop/s according to the organization’s benchmarks. Let’s take a look at top 6 fastest super computers of today’s world.
1. Tianhe-2
Tianhe-2 is a 33.86-petaflops supercomputer located in Sun Yat-sen University, Guangzhou, China. It was developed by a team of 1,300 scientists and engineers. It is the world’s fastest supercomputer according to the TOP500 lists.
Tianhe-2 is powered by 3 million Intel Xeon E5-2692vv2 12C cores of 2.2 GHz clock speed. The processors are connected in a concert way to give out high transfer speed. The main processor is coupled with Intel Xeon Phi 31S1P coprocessor. Tianhe-2 has been the world’s fastest super computer for past four years.
2. Titan
Titan 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.
The supercomputer records the speed of 17.6 petaflops. It is powered by 2.2 GHz AMD Opteron 6274 16C processors.
3. Sequoia
IBM Sequoia is a petascale Blue Gene/Q supercomputer constructed by IBM for the National Nuclear Security Administration as part of the Advanced Simulation and Computing Program (ASC).
The computer records the speed of 17.17 petaflops. It is powered by 1.6 GHz Power BQC 16C processors. The speed is good enough to perform nuclear explosion simulations.
4. K-Computer
This Japanese computer is world’s fourth fastest super computer. It is based on SPARC processor. The computer records the speed of 10.5 petaflops. It is powered by 2GHz SPARC64 VIIIfx 8C processors. Surprising part is, this supercomputer runs on Linux!
5. Mira Blue Gene
This is another IBM Blue Gene Design. The super computer is located at Argonne National Laboratory in USA. The computer has recorded the speed of 8.6 petaflops. It is powered by 786,000 1.6GHz Power BQC 16C cores. It is being used to solve modeling and simulation problems.
6. CSCS Piz Daint
This is another example of Cray design. CSCS Piz Daint is known as one of the fastest super computers in Europe. The computer records the speed of 6.3 petaflops. It is powered by 2.6 GHz Intel Xeon E5-2670 8C processors coupled with cK20x coprocessors. The high end processors are designed for top server math performance.
