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. Mapping the wiring diagram of the brain is crucial to untangling its vast communication network and understanding how it represents and processes information. (IBM Research)

Results of massively parallel cortical simulations of a cat cortex, with 1.5 billion neurons and 9 trillion synapses, running on Lawrence Berkeley National Laboratory’s Dawn Blue Gene/P supercomputer, will be presented by IBM and LLNL researchers today at the SC09 Conference on High Performance Networking and Computing in Portland.

“The simulations, which incorporate phenomenological spiking neurons, individual learning synapses, axonal delays, and dynamic synaptic channels, exceed the scale of the cat cortex, marking the dawn of a new era in the scale of cortical simulations,” according to the ACM proceedings abstract.
