SUPERCOMPUTERSESSENTIAL ENGLISH – PEN0055

Definition of a SupercomputerA computer which has the capability to :-

• Perform complex calculations in the extreme scale.

• Solve a single large problem in the shortest amount of time.

• Generate a real world scale simulation of events.

Size of a Supercomputer• Occupy a floor area as big as anywhere between one to two soccer fields.

Fujitsu’s K Supercomputer IBM’s Blue Gene Supercomputer

Speed of a Supercomputer• Faster than you could imagine. • FLOPS (Floating Point Operations per Second) or instructions per second is used to measure

the speed of a supercomputer.

• In terms of scale, supercomputer is about 100,000 times faster than an average desktop

computer.

• In terms of numbers, supercomputer is designed to process instructions at the rate of a

whopping 50,000,000,000,000,000 instructions per second (50 petaFLOPS).

Usage of a Supercomputer

• Computational Science

• Quantum mechanics.

• Weather forecasting.

• Oil & gas exploration.

• Physical simulation.

• Nuclear weapons detonation.

• Nuclear fusion.

Top 2 Fastest Supercomputers1. Tianhe-2

Located in National Super Computer Center in Guangzhou, China. Peak performance: 54 petaFLOPS.

2. Cray Titan Situated in Oak Ridge National Laboratory in United States. Peak performance: 27 petaFLOPS.
