The full paper might be useful: http://conferences.computer.org/sc/2012/papers/1000a085.pdf
The paper seems to indicate that the sim is running 388 times slower than real-time. I guess we're not 100% there hardware-wise yet? Good.
this is worryingly fast IMO.
Thanks for this. The latest research report 10^14 already appears to be a significant update on that paper.
IBM now report roughly eight times as many simulated neurons and synapses, while the slow-down has gone from ~400x real-time to ~1500x real time. That works out at a factor > 2 in hardware improvement within a matter of months. They are using a custom hardware architecture and presumably there are still a lot of optimisations to be made. It can't be very long before this can run in real time.
As said in other comments, nobody knows how to program this yet...
