“Petascale” supercomputers can process one quadrillion (1015) (1000 trillion) FLOPS.

Exascale is computing performance in the exaFLOPS (EFLOPS) range.

An EFLOPS is one quintillion (1018) FLOPS (one million TFLOPS).

## How big is a supercomputer?

The supercomputer — which fills a server room the size of two tennis courts — can spit out answers to 200 quadrillion (or 200 with 15 zeros) calculations per second, or 200 petaflops, according to Oak Ridge National Laboratory, where the supercomputer resides.

## What is the size of microcomputer?

» Micro Computer

Microcomputer is at the lowest end of the computer range in terms of speed and storage capacity. Its CPU is a microprocessor. The first microcomputers were built of 8-bit microprocessor chips.

## What is the storage capacity of a supercomputer?

The system, which will be named Spider II, will have a capacity of 40 petabytes. If you have a 1 terabyte hardrive in your computer now, it would take 40,960 of them to have the same memory capacity.

## What defines a supercomputer?

A supercomputer is a computer that performs at or near the currently highest operational rate for computers. Traditionally, supercomputers have been used for scientific and engineering applications that must handle very large databases or do a great amount of computation (or both).
