    The most accurate simulation of the human brain to date has been carried out in a Japanese supercomputer, with a single second’s worth of activity from just one per cent of the complex organ taking one of the world’s most powerful supercomputers 40 minutes to calculate.

    Researchers used the K computer in Japan, currently the fourth most powerful in the world, to simulate human brain activity. The computer has 705,024 processor cores and 1.4 million GB of RAM, but still took 40 minutes to crunch the data for just one second of brain activity.

    The project, a joint enterprise between Japanese research group RIKEN, the Okinawa Institute of Science and Technology Graduate University and Forschungszentrum Jülich, an interdisciplinary research center based in Germany, was the largest neuronal network simulation to date.

    It used the open-source Neural Simulation Technology (NEST) tool to replicate a network consisting of 1.73 billion nerve cells connected by 10.4 trillion synapses.

    While significant in size, the simulated network represented just one per cent of the neuronal network in the human brain. Rather than providing new insight into the organ the project’s main goal was to test the limits of simulation technology and the capabilities of the K computer.

    Through their efforts, the researchers were able to gather invaluable knowledge that will guide the construction of new simulation software. In addition, their achievement offers neuroscientists a glimpse of what can be achieved by using the next generation of computers - so-called exascale computing.

    Exascale computers are those which can carry out a quintillion floating point operations per second, which is an important milestone in computing as it is thought to be the same power as a human brain and therefore opens the door to potential real-time simulation of the organ’s activity.

    Currently there is no computer in existence that powerful, but Intel has said that it aims to have such a machine in operation by 2018.

    “If petascale computers like the K computer are capable of representing one per cent of the network of a human brain today, then we know that simulating the whole brain at the level of the individual nerve cell and its synapses will be possible with exascale computers - hopefully available within the next decade,” said one of the scientists, Markus Diesmann.

    It seems we have away to go still before they do anything substantial?

    it will only need to get a few % smarter before it decides were are its problem, watches terminator and realises what it should do,

    OK, so are we going to run Mach3 or LinuxCNC on it?

    Discuss!

    Does it have a parallel port?

    40mins*60/1%=240,000 times 'worse' than the human brain. So if Moore's law continues, we're still a good 30 years away from a full real-time simulation, unless they come up with better algorithms to simulate artificial neurons.

    So when's it signing up to mycncuk?
    Old router build log here. New router build log here. Lathe build log here.

    Yup, 40 mins of cpu time is about one second of a typical brain. I still bet that the average router can hit a limit switch and react before I can reach the e-stop!

    "Supercomputer models one second of human brain activity"

    ...& the footnote to this story - the same computer/program easily achieved few hours brain activity modeled on those domiciled North of the Watford gap.

    ha, ha, true, but, I would be surprised if anyone south of the Watford gap would have the time to extract themselves out of there own glutius maximus , to be able to measure there own brain activity without having to stick the probe up there eastender to mesure it.
