What is a Supercomputer?

A supercomputer is an advanced computing system capable of performing trillions of calculations per second, measured in FLOPS (Floating Point Operations Per Second). These machines are built with thousands or even millions of processors or cores that work together through parallel processing to execute multiple tasks simultaneously. Modern supercomputers operate at petaflop speeds (10¹⁵ FLOPS) or higher, enabling them to tackle tasks that are far beyond the capabilities of standard computers.

Supercomputers are not designed for everyday tasks like browsing the internet or word processing. Instead, they are specialized tools used in fields such as scientific research, engineering, medicine, artificial intelligence, and commercial applications where massive data analysis or intricate simulations are required. For example, supercomputers play a critical role in climate modeling, space exploration, drug discovery, and AI development.
