Supercomputers are reserved for heavy, data-intensive computations. Mostly used by scientists, engineers, and analysts to run programs and solve problems that need to crunch through massive amounts of data. Commonly, they are used for visual simulations, weather forecasting, and scientific analysis. Most notably, researchers can use these machines to create visualizations of medical conditions in order to study and treat them. Supercomputers helped doctors better understand the Covid-19 pandemic for instance.
