The world’s fastest “supercomputer“ has a computing power of 122,300 teraflops, i.e. it can carry out 122,000 trillion floating point operations per second. While that only sounds like Chinese to the uninformed ear, Summit, the computer topping the current TOP500 ranking of supercomputers, is not located in China. Even though the far eastern country is one of the most important hubs for supercomputing, the United States, its direct competitor in the never-ending run for the world’s most powerful calculator, is currently home of the aforementioned supercomputer which was revealed at the Oak Ridge National Laboratory yesterday. Supercomputers are used to run complicated simulations that involve a large number of variables. Common use cases include economic and climate modeling, neurological research and nuclear science. The following chart ranks the Top 10 systems based on their computational performance.
