China has built the Tianhe-1A, the world’s fastest supercomputer, which is capable of 2.57 quadrillion computing operations per second, pulling ahead of the United States in the global supercomputing race, according to the 36th edition of TOP500 list of the world’s most powerful supercomputers. The Tianhe-1A is installed at the National Supercomputing Center (NSCC) in the north China port city of Tianjin.
Tianhe-1A was followed by the former No. 1 system, the U.S.-made Cray XT5 “Jaguar” at the U.S. Department of Energy’s Oak Ridge Leadership Computing Facility in Tennessee.
The Jaguar system performs at 1.75 quadrillion per second, 92 percent slower than Tianhe-1A, running Linpack, the benchmark used to officially determine the speed of supercomputers.
