Original title: The World's fourth super simulation 1 seconds of human brain computing needs 2 days and a half

Researchers in Japan and Germany have completed one of the largest human cranial nerve simulations in history, using the "calculator" that is currently the fourth-ranked Japanese supercomputer K Computer (Beijing), and the results are quite impressive.

This simulates the activity of 1.73 billion nerve cells in 1 seconds (which, of course, is not a complete number of human brain cells), using the K-Computer 82,944 processor +1PB memory for calculation. As a result, it takes 40 minutes to complete a 1-second simulation calculation. Assuming that the completion time is linearly proportional to the size of the simulated nerve, it takes 2.5 days to simulate the entire brain's 1-second operation.

K Computer is currently ranked fourth in the world, with a floating-point computing capacity of 10.51Petaflops per second (petajoules). But it's a weak one compared to the computational power of the human brain.

Still, researchers are encouraged, and the project leader, Markus Diesmann, said in a press release: "If computer such petaFLOPS (petajoules per second) scale can simulate 1% of human neural networks, in the next ten years, The simulation of the entire human brain is expected to be realized in the Exaflops (Exascale per second) scale. ”
