Japan's K Supercomputer

Researchers from the RIKEN HPCI Program for Computational Life Sciences, by using the full computational power of the Japanese K supercomputer, have carried out the largest general neuronal network simulation to date.    Image © RIKEN

The simulated network only represented 1% of the neuronal network in the brain.



“Using NEST, the team, led by Markus Diesmann in collaboration with Abigail Morrison both now with the Institute of Neuroscience and Medicine at Jülich, succeeded in simulating a network consisting of 1.73 billion nerve cells connected by 10.4 trillion synapses. To realize this feat, the program recruited 82,944 processors of the K computer.  The process took 40 minutes to complete the simulation of 1 second of neuronal network activity in real, biological, time.”

“If peta-scale computers like the K computer are capable of representing 1% of the network of a human brain today, then we know that simulating the whole brain at the level of the individual nerve cell and its synapses will be possible with exa-scale computers hopefully available within the next decade,” explains Diesmann.
