Supercomputer


What is a Supercomputer?

A supercomputer is a computer that performs at a higher level than a general-purpose computer. Originally, the term supercomputer was used to describe the fastest computers in the world, but today this term usually refers to machines that can perform more than 1 trillion floating-point operations per second (1 teraflop). Supercomputers are commonly used for scientific simulations, data processing, and cryptanalysis. This article will discuss some of the most important supercomputers throughout history and explain what supercomputers are capable of doing today and in the future.

History

The term supercomputer was coined in 1986 by Jack Dongarra of Argonne National Laboratory, when he identified six computers that fit his criterion of having speed-performance ratios higher than 100 million theoretical operations per second (MOPS): The CDC 7600; an IBM RT; and three vector processors, specifically an Intel Paragon, an IBM ASC and a Cray-1.

List of Supercomputer

  • IBM Roadrunner, 
  • Cray XT5, 
  • Cray X1, 
  • SGI Altix ICE 8200, 
  • Cray C90 MPP, 
  • K Computer (SuperMUC), 
  • Jaguar (Blue Gene/L), 
  • Intel Paragon XP/S System.

There are two kinds of supercomputers, those that run at peak performance for long periods of time and those which run at peak performance for short bursts of time; these are called batch computing and interactive computing respectively. While it’s easy to see why short-burst computing has gained in popularity over time – computational power grows at a much faster rate than memory capacity – many applications can be applied to either type of machine.

Importance

What is a supercomputer and why do we need them? A supercomputer can be defined as a computer that performs at least 106 floating-point operations per second (FLOPS). Most of us use computers every day. These devices are not considered supercomputers, although they may be more powerful than your personal computer. The existence of supercomputers dates back to 1960 when Control Data Corporation (CDC) introduced its 6600 system.

The Future

With computer technology advancing so rapidly, it’s hard to imagine what kind of computers we’ll be using in just 10 years. Researchers are working on supercomputers made out of DNA, quantum computers that work on subatomic level and supercomputers that can fit into your pocket. Although they may sound unbelievable, these innovations might be with us sooner than you think. It’s exciting to think about how our society could improve by having access to even more computing power!
