Final answer:
The claim that the world's fastest supercomputer has 9,000,000 computing cores is false; even leading supercomputers like China's Sunway TaihuLight have fewer cores but still perform at incredibly high speeds.
Step-by-step explanation:
The statement about the fastest supercomputer in the world having 9,000,000 computing cores is false. Current top supercomputers have an impressive number of cores, but not in the millions.
For example, China's Sunway TaihuLight supercomputer, which was the world's fastest from 2016 to 2018, operates with 10,649,600 cores provided by its 40,960 Sunway SW26010 processors. Each of these processors contains 260 cores. While the TaihuLight is an incredible machine and performs up to 125.44 petaflops, it does not reach the count of 9,000,000 cores alone.
