Neurosynaptic Cores This network of neurosynaptic cores is derived from wiring in the monkey brain. The cores are clustered into regions, also inspired by the brain, and each core is represented by a point along the ring. Arcs connect the different cores to each other. Each core contains 256 neurons, 1024 axons, and 256×1024 synapses. IBM

Simulated Brain Ramps Up To Include 100 Trillion Synapses

IBM is developing a cognitive computing program under a DARPA program and just hit a major high.

The Sequoia supercomputer at Lawrence Livermore National Laboratory, recently crowned world champion of supercomputers, just simulated 10 billion neurons and 100 trillion connections among them–the most powerful brain simulation ever. IBM and LLNL built an unprecedented 2.084 billion neurosynaptic cores, which are an IBM-designed computer architecture that is designed to work like a brain.

IBM was careful to say it didn’t build a realistic simulated complete brain– “Rather, we have simulated a novel modular, scalable, non-von-Neumann, ultra-low power, cognitive computing architecture,” IBM researchers say in an abstract (PDF) of their new paper. It meets DARPA’s metric of 100 trillion synapses, which is based on the number of synapses in the human brain. This is part of DARPA’s cognitive computing program, called Systems of Neuromorphic Adaptive Plastic Scalable Electronics (SyNAPSE).
