IBM Neural Tissue Simulator
The Neural Tissue Simulator is software that simulates large-scale biologically-realistic neural networks. It was developed by IBM, is written in C++, and runs on IBM's Blue Gene/P supercomputers. A paper published in September 2011 describes the simulation of 1,024,000 neurons and 10 billion synapses. 4,096 nodes of a Blue Gene/P took 6.1 hours to simulate 100 milliseconds of neurophysiology. The simulation time step was 10 µs. Each neuron was represented by ~1,000 compartments. The neurons were arranged in cortical columns, with 20x20 minicolumns per column, and 20 neurons per minicolumn. Researchers were James Kozloski (LinkedIn) and John Wagner. See the video of a presentation talk. They estimate that this technology could be scaled up to acheive a complete human brain simulation within a decade.
