Supercomputers have held a position of huge esteem within the technology space. They are used for many things, including climate modeling, disease research, and nuclear science.
They are also used to run complicated simulations that involve many variables. Recently, supercomputers have been used to track the spread and mutation of the coronavirus.
Supercomputers are often ranked in terms of the number of computations per second. These so-called TeraFLOPS are units of computing power equal to one trillion (10¹²) floating-point operations per second.
