This week, China’s Sunway TaihuLight officially became the fastest supercomputer in the world. The previous champ? Also from China. What used to be an arms race for supercomputing primacy among technological nations has turned into a blowout.
The Sunway TaihuLight is indeed a monster: theoretical peak performance of 125 petaflops, 10,649,600 cores, and 1.31 petabytes of primary memory. That’s not just “big.” Former Indiana Pacers center Rik Smits is big. This is, like, mountain big. Jupiter big.
