What are super computers?

Are they computer with super powers.

[dropcap]Y[/dropcap]es indeed they are, Super computer is broad term used for fastest computers currently available. These are specially designed to solve the complex problems that are no way handled by ordinary PCs

The striking difference between a super computer and mainframe is that a super computer utilizes all its power in executing a few complex programs as fast as possible and whereas a mainframe employs all its power to execute many programs concurrently.

These workhorses use variants of UNIX operating system. FORTRAN is the mainstay language of scientific and technical programming, as it is well suited to describe simulations. C is becoming more common for use in super computer applications but is currently behind FORTRAN in use.

Super computer’s speed is measured in Floating Point Operations per Second(FLOPS), in units of mega-flops(MFLOPS), giga-flops(GFLOPS) and Peta-flops(PFLOPS).

Here is a list of top-5 Super computers of this generation. The power of #1 will outrage you.


Mira super Computer
Mira super Computer

Owned by US Department of Energy (DOE) and is located at Argonne National Laboratory, Illinois. It is clocked at 8.58 Peta-flops and is one among the most energy efficient. It uses IBM’s Bluegene/Q platform with 786000 core processors

4)K computer (Japan)

fujitsu's K-Computer.

Fujitsu’s K computer is installed at Japan’s RIKEN Advanced Institute for computational science with 705000 SPARC64 VIII FX Octa-core processors it performs 10.5 Peta-flops to solve climate challenges faced by this contemporary world.

3)Sequoia (USA)


Owned by Berkeley National Laboratory, California is another IBM machine with Bluegene/Q platform with 1.6 million 16 core processors with its speed of 17.2 Peta-flops it concentrates on extending life of aging nuclear weapons and experiments on nuclear fusion.

2)Titan (USA)

Titan Super Computer

Hosted at the US Department of Oak Ridge National Observatory at Harvard, this gigantic machine is backed up by Nvidia Tesla GPUs and 561000 AMD Opteron 6274 16 core 2.2 GHZ processors. Its speed of 17.6 Peta-flops is utilized to perform several scientific researches.

1)Tianhe-2 (China)

Tianhe-2 hardware

This is definitely the Big brother of all super computers and is named after Milky way. This Beast processes at terrific speed of 33.9 Peta-flops that’s incredible. It is developed b china’s national university of Defense and Technology to process Quadrillion of calculations per second. It uses Intel Xeon phi and Intel XeonE5 processors.

With these artificial mega minds under the hood. Scientists were working in the fields of quantum computing climatology, Nuclear science and medicine and space research.

Soon these Super Intelligent computers will be surpassed by Artificially Intelligent machines
