Supercomputer ?

 A supercomputer is a type of computer with extremely high processing power and speed, designed to perform complex calculations and simulations that require a large amount of data processing. They are typically used in scientific and engineering applications, such as weather forecasting, molecular modeling, and simulations of nuclear explosions.

Supercomputers are typically built from thousands of interconnected processors working together in parallel. They also use specialized hardware such as high-speed network connections, large amounts of RAM, and specialized processing units such as graphics processing units (GPUs) or field-programmable gate arrays (FPGAs) to accelerate specific tasks.

The world's most powerful supercomputers are currently capable of performing billions of calculations per second (known as floating-point operations per second, or FLOPS) and are used for cutting-edge research in fields such as climate science, astrophysics, and artificial intelligence.
