Supercomputers are the most powerful computing machines capable of performing trillions of instructions per second. They are used for performing complex calculations. They use vector processors. Supercomputers exhibit intensive parallelism. They are large and very expensive. The speed of supercomputers is measured in FLOPS.

Examples
Cray-1, Cray-2, Fujitsu VP 2600/10, PARAM 10000, etc

Applications
Supercomputers are used for weather forecasting, weapons research and development, in atomic,
plasma and nuclear analysis, space research and so on.
