Supercomputer reproduced 1 second of the brain
Is it possible to truly reproduce the work of the human brain in the modern binary computer? Specialists in artificial intelligence are arguing about this for decades, but have not come to a final conclusion. One way or another, but a group of German and Japanese engineers using the most ambitious re-created supercomputer simulations of brain activity on the computer. participated in the simulation 1.73 billion virtual neurons connected together 10.4 trillion synapses, and it was launched on the Japanese K supercomputer Supercomputer, which has become the most powerful computer in the world in 2011.
To simulate only 1 second of life the brain power of 10 petaflops supercomputer / s took 40 minutes of computation. The Japanese research institute RIKEN say their model reproduced the 1 second of real activity of the brain in real time. To achieve this, the engineers took 82944 microprocessor. K Supercomputer Today is the fourth most powerful supercomputer in the world. How to tell the scientists, in their model, each brain synapses received by 24 bytes of memory.
The simulation was performed using open source software NEST and took about 1 petabyte of main memory (the equivalent capacity of 250,000 ordinary PC). Synapses were randomly grouped together experts and initially wanted to determine the limit of the computational capabilities of K. Recall that the peak power is K Supercomputer 10.51 petaflop / s, installed inside the SPARC processors with a total of 705,024 cores.
"If computers petamasshtaba such as K, are able to reproduce approximately 1% of the activity of the brain, we now know that the simulation of the whole brain activity is possible by superkompyutrerov with ekzamasshtabami that will become available in the world after about 2020, "- says Marcus Dismann of the Institute of Neuroscience and Medicine in Germany . ekzamasshtaba Computers are capable of producing at least a quadrillion floating point operation per second. Researchers disagree as to when such a system will be, but most of them believe that it will happen in about 2020-2022 years. The Japanese institute RIKEN already planning to create a supercomputer, which will surpass the power of K 100 times.
