Supercomputing is the processing of large and complex, or data-laden problems, using the concentrated computer resources of multiple computer systems working in parallel. These systems work at the maximum potential performance of any computer. Supercomputing enables problem-solving and data analysis that would be impossible, too time-consuming, or more costly to perform with standard computers
U.S. has surrendered its commanding lead in the world’s top supercomputers. On the Top 500 list of the world’s fastest supercomputers , U.S. in 2005 controlled almost half the world’s top supercomputers; it now controls less than a quarter, with China now controlling the largest number of the fastest supercomputers
Changing the benchmark to the top 100 supercomputers , U.S. leadership is on a downward trajectory. The U.S.’s lack of investment over the past two decades is best demonstrated by China gaining the top spot on the list in 2010 and the U.S. did not recapture that spot until 2018.
