Lees ik net dit artikel:

http://tweakers.net/nieuws/47303/Supercomputer-simuleert-muizenbreintje.html

De eerste stap op weg naar een artificieel mensenbrein, en daarmee Artificial Intelligence?
Watvoor "spontane" processen zouden zich hebben voltrokken vraag ik me dan af... Vind het in ieder geval interresant om te lezen, en misschien ergens ook wel een beetje eng dat ze dit allemaal al kunnen!

Vraag je ook eens af wat voor "spontane" processen zich in jouw brein voltrekken.

ze moeten toch maar eens opschieten om de processing power van computers weer eens wat op te krikken want een duizendste muizen-hersens op een tiende snelheid is natuurlijk niks.

kan je wel weer nagaan hoe complex een en ander is

Interesting, there are some neural processors being made. My father is designing a new processor and he has taken an interest in neural processing. The brain is extremely complex and far from being understood last I heard.

Neural processors are merely based on the way we understand the brain works. There is a lot of blank space that is filled based on existing technology.

    Hoewel de simulatie maar een miniem fragment van het muizenbrein besloeg, bleek de opdracht een behoorlijke aanslag op de rekenkracht van Blue Gene, die over 4096 processors met elk 256MB geheugen beschikte


The above is incorrect. Each processor unit is dual core (PowerPC 440) and contains 2 MB of on-die cache. Each processor enclosure (rack) contains 4096 processors.

Blue Gene/L consists of 65,536 processors (16 enclosures for those that are interested).

    Blue Gene/P

    On June 26, 2007, IBM unveiled Blue Gene/P, the second generation of the Blue Gene supercomputer. Designed to run continuously at one petaflops, it can be configured to reach speeds in excess of three petaflops. Furthermore, it is at least seven times more energy efficient than any supercomputer, accomplished by using many small, low-power chips connected through five specialized networks. Four 850 MHz PowerPC 450 processors are integrated on each Blue Gene/P chip. The one-petaflops Blue Gene/P configuration is a 294,912-processor, 72-rack system harnessed to a high-speed, optical network. Blue Gene/P can be scaled to an 884,736-processor, 216-rack cluster to achieve three-petaflops performance. A standard Blue Gene/P configuration will house 4,096 processors per rack.



This supercomputer is a lot faster than the one they used to simulate the mouse brain. Maybe they should try it on this one (medical science calculations will probably take presidence over simulating a mouse brain though).
