The Japanese supercomputer was much slower than the human brain

Mankind develops supercomputers year by year, striving to create a computer capable of working at speeds comparable to the human brain. But while the goal is still quite far to achieve. Researchers downloaded the most detailed model of the brain region, which covers only one percent of the brain, to the Fujitsu "K computer" supercomputer, and simulated on the computer only one second of the human organ work.

On all calculations, the fourth largest supercomputer in the world took 40 minutes of computer time. Thus, the speed of the computer is 2400 times slower than the speed of the human brain.

To create the simulation environment, the specialists used the open software Neural Simulation Technology (NEST), which loaded a network of 1.73 billion nerve cells, combined 10.4 trillion synapses, reports popsci.com. Although these figures are impressive, they represent only one percent of the total neural network of the human brain. The modeling of the brain was carried out by the "bottom-up" method.

Studying the available data, scientists say that only ex-computers capable of performing a quintillion of floating-point operations per second will be able to cope with the task of creating a complete and accurate model of the human brain at an acceptable time. Unfortunately, such computers do not exist yet, but in Japan by 2020 they plan to create such a computer.
