Its the era of computers and everyone knows what they do, its advantages and disadvantages but somehow people saw need of more advanced tech which can solve billions and trillions parts calculation in milliseconds or more quickly. Sunway taihu light Supercomputers play an important role in the field of computational science, and are used for a wide range of computationally intensive tasks in various fields, including quantum mechanics , weather forecasting , climate research, molecular modeling (computing the structures and properties of chemical compounds, biological macromolecules, polymers, and crystals), and physical simulations (such as simulations of the early moments of the universe, airplane and spacecraft aerodynamics, the detonation of nuclear weapons, and nuclear fusion ). Throughout their history, they have been essential in the field of cryptanalysis. Every developed and developing country began the race of building super computers and were succesful in building them.
