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.
