Supercomputers are universal tools for carrying out tasks requiring high-performance computing that could not be handled by traditional computers or server systems. The primary objective is to serve applications requiring extreme amounts of computing, extreme speed, or huge memory capacities.

For comparison, a laptop with a 3-GHz processor is capable of completing 3 billion computations in a second. The performance of the 5 petaflops Komondor is 5 trillion (million times billion) floating- point operations per second.

Supercomputers may help find solutions to global challenges and answers to scientific questions and may help model the weather around the globe, the biosphere, the functioning of living organisms, and the birth of galaxies. In everyday practice, they help with tasks such as weather forecasting, climate research, telecommunications, traffic management, energy production, production optimisation, or customised medicine with the rapid processing of genomic data.
