10 MOST POWERFUL SUPERCOMPUTERS

The bi-annual list of world's 500 most powerful supercomputers is out. Wondering which are these most powerful supercomputers and where are they installed? We bring to you 10 most powerful supercomputers from the list.

Tianhe-2




Tianhe-2, a supercomputer developed by China’s National University of Defense Technology, retained its position as the world’s No. 1 system with a performance of 33,862.7 TFlop/s on the Linpack benchmark. The supercomputer with 1,024,000GB memory runs on Kylin Linux operating system. Tianhe-2 is powered by Intel Xeon Phi processors.

Titan



Titan, a Cray XK7 system installed at the Department of Energy’s (DOE) Oak Ridge National Laboratory in the US, is the second most powerful supercomputer globally. The system achieved 17,590.0 TFlop/s on the Linpack benchmark. Titan is one of the most energy efficient systems on the list consuming a total of 8.21 MW and delivering 2.143 gigaflops/W. Titan uses NVIDIA GPUs to accelerate computation. 

Sequoia




Sequoia, an IBM BlueGene/Q system installed at DOE’s Lawrence Livermore National Laboratory in the US, once again emerged as the third most powerful supercomputer. It first entered the rankings in 2011 and achieved 17,173.2 TFlop/s on the Linpack benchmark. Sequois has Linux as operating system and packs 1,572,864GB memory.


Fujitsu’s K computer





The fourth most powerful supercomputer in the world is Fujitsu’s K computer. The supercomputer is installed at the RIKEN Advanced Institute for Computational Science (AICS) in Kobe, Japan, and scores 10,510.0 TFlop/s on the Linpack benchmark. K computer also has a Linux operating system. 


Mira



Mira, a BlueGene/Q system installed at DOE’s Argonne National Laboratory in the US, is the world's fifth most powerful supercomputer. It scores 8,586.6 TFlop/s on the Linpack benchmark. Mira also runs on Linux operating system.


Piz Daint



At number sixth is a new entrant in the list: Piz Daint. A Cray XC30 supercomputer, Piz Daint is installed at the Swiss National Supercomputing Centre (CSCS) in Lugano, Switzerland, and is now the most powerful system in Europe. Piz Daint achieved 6.2710 TPflop/s on the Linpack benchmark. The supercomputer is also the most energy-efficient system in the TOP10 consuming a total of 2.33 MW and delivering 2.7 Gflops/W. Piz Daint is powered by NVIDIA GPUs and is based on Cray Linux Environment operating system. 


Stampede



Stampede supercomputer installed at the Texas Advanced Computing Center of the University of Texas in the US, ranks at number seventh. Stampede runs on Intel Xeon Phi processors. Stampede achieved 5,168.1 TFlop/s on the Linpack benchmark. The supercomputer too runs on Linux operating system. 


JUQEEN



An IBM BlueGene/Q system called JUQEEN is the world's eigth most powerful supercomputer. JUQEEN is installed at the Forschungszentrum Juelich in Germany. The system scores 5,008.9 TFlop/s on Linpack benchmark. The system has 458,752GB as memory.


Vulcan



The world's ninth most powerful supercomputer is Vulcan. Another IBM BlueGene/Q system, Vulcan is installed at Lawrence Livermore National Laboratory in the US. The system scores 4,293.3 TFlop/s on Linpack benchmark. The Linux-based system has 393,216GB memory. 


SuperMUC



At number tenth on the list is another supercomputer from Europe called SuperMUC. The supercomputer is installed at Leibniz Rechenzentrum in Germany. The Linux-based system scores 2,897.0 TFlop/s on Linpack benchmark.
