IBM. Neurosimulator Compass — the human brain in the processor

At the conference, Supercomputing 2012 company IBM presented the results of Neurosimulator Compass Supercomputer Sequoia (second in the world ranking of supercomputers). Was first reached the scale that corresponds to the human brain — 530 billion neurons and 137 trillion synapses. Simulation occurred in 1542 times slower than real time. It used all 1,572,864 cores and half a petabyte of memory.

Compass — a new computer simulation system architecture TrueNorth, which IBM calls a "big brother Watson». Unlike our usual computers based on the von Neumann architecture, TrueNorth built in the image of the brain, based on the developed IBM «neyrosemanticheskih cores" — chips containing silicon neurons and synapses. Each chip contains 256 neurons, 1024 256h1024 axon and synapse. Area of the chip, manufactured using the 45-nanometer technology — 4.5 mm2. In the record-breaking simulation was modeled operation of such nuclei billion in 2084.

This work was done as part of DARPA SyNAPSE, whose ultimate objective — to create a neural computers comparable to the brain of higher mammals, both in speed and cognitive abilities, as well as in terms of compactness and energy. So, in fact it is about creating the brain to "terminator". Here are some of its features:

— 10 billion neurons
— 100 trillion synapses
— energy in the range of 1 kW
— occupied space — less than 2 dm3
— interfaces for sensory and motor functions

IBM is working on a "cognitive computer" for DARPA for several years. So, in 2009, presented the results on the scale neyorsimulyatsii cat brain. It is too early to talk about a realistic simulation of the human brain, because apart from a sufficient number of neurons must also be aware of their connection scheme and, most importantly, a program that controls the operation of the brain. In this respect, too, there is progress. One of the simulations in the DARPA SyNAPSE was based on the wiring diagram of neural systems in the brain of macaques received as part of the project CoCoMac.


Creating the Terminator successfully continues …
