IBM announced today a new advance in the simulation of biological brains on computer hardware. As part of the DARPA SyNAPSE project, the Cognitive Computer Team at the IBM Almaden Research Center has achieved a large-scale simulation based on a new algorithm, called BlueMatter, that synthesizes neurological data.
BlueMatter, a new algorithm created in collaboration with Stanford University, exploits the Blue Gene supercomputing architecture in order to noninvasively measure and map the connections between all cortical and sub-cortical locations within the human brain using magnetic resonance diffusion weighted imaging.
The result achieved was real-time simulation of a cat-level cortex containing 1 billion spiking neurons and 10 trilling synapses. The simulation required 147,456 CPUs and 144 terabytes of memory.
