"SpiNNaker human brain supercomputer"

Thought it could be interesting, from
The University of Manchester

It will have over 50,000 chips of this type with 16 (18-2) productive cores each. If I understand correctly, the idea is to have the cores simulate a neuron each, and allow the cores to communicate among themselves without a centralised memory management.

Wow, imagine the kinds of simulations they’ll be able to run on that monster. Of course a million cores simulating a neuron each (though insanely impressive) doesn’t really qualify it as a “human brain” supercomputer. It could probably fully simulate a cockroach brain though.


#4

In the original article they mention to try to simulate a billion neurons, so maybe each core is supposed to simulate a thousand or even more?


#5

AFAIK. Each chip has 16 cores (17 actually, one if for redundancy). In which 15 is available for simulating neurons and each can handle up to 100 neurons.
So that’s 50,000x100x15 = 75,000,000 neurons on full performance?
