The brain is called Semantic Pointer Architecture Unified Network, or, rather creepily, “Spaun," and is reported behind a firewall in Science but summarized here. Helpfully, the research team made videos of Spaun carrying out various tasks.
Spaun was created using the Nengo simulation software package, and run on clusters Orca and Kraken of the SharcNet High Performance Computing Consortium. In other words, it is run on a Linux based supercomputer. It takes up about 24GB of ram and takes about 2.5 hours of processing for one second of simulated time."
