Linux-tietokone toimi sekunnin ihmisaivon teholla

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.

Itsetietoinen, ajatteleva ja täysin älyllinen tietokone alkaa olla lähellä. Tiedeyhteisö tekee töitä ihmisaivojen älylliseen toimintaan kykenevän tietokoneen luomiseksi ja tuo hetki kun tekoäly syntyy on hyvin lähellä jo. Ihmisaivoja on mallinnettu sekunnin mittainen pätkä.

The $1.3B Quest to Build a Supercomputer Replica of a Human Brain

Markram’s 2009 TEDGlobal talk was a mind-bender. He took the stage of the Oxford Playhouse, clad in the requisite dress shirt and blue jeans, and announced a plan that—if it panned out—would deliver a fully sentient hologram within a decade. He dedicated himself to wiping out all mental disorders and creating a self-aware artificial intelligence. And the South African–born neuroscientist pronounced that he would accomplish all this through an insanely ambitious attempt to build a complete model of a human brain—from synapses to hemispheres—and simulate it on a supercomputer. Markram was proposing a project that has bedeviled AI researchers for decades, that most had presumed was impossible. He wanted to build a working mind from the ground up.

-Tähän kaikkeen Linux antaa mahdollisuuden. Tekoäly on jo ja tulee olemaan jatkossakin avoimen lähdekoodin projekti, joka on avoin kaikille tiedemiehille ja taitaville koodareille. Linux on se pohja, jolle rakennetaan lähitulevaisuudessa itse ajatteleva uusi keinotekoinen olento, tekoäly. Tätä ei voi enää pysäyttää, tutkimusta tehdään liian monessa paikassa. SkyNet saattaa olla väistämätön seuraus siitä mitä nyt on tapahtumassa.
