Riken announced on the 17th, the Center for Computational Science’s (Kobe) supercomputer “Fugaku,” in the four categories for performance rankings became No. 1 in the world, following the previous time’s (success) in June. It’s the first time in the world a supercomputer has been awarded the title of “quadruple crowns” for two consecutive terms. Among those in the Top 500 category, (Fugaku’s) computational speed reached 442 quadrillion 10 trillion times per second, compared to the second place U.S. Oak Ridge National Labratory’s supercomputer (148 quadrillion 600 trillion times) demonstrated three times the performance. The Top 500 ranking’s third place went to the United States, fourth place went to a Chinese supercomputer.

It’s a supercomputer at the Center for Computational Science (Kobe).

2) What is it the first in the world to achieve?


It became No. 1 in the world in four performance ranking categories for supercomputers for two consecutive terms.

3) How fast is its calculation speed?


442 quadrillion 10 trillion times per second.
