Deep South – A Neuromorphic Supercomputer
Australian researchers at the International Centre for Neuromorphic Systems (ICNS) at Western Sydney University have announced they are building what they are calling Deep South (based on IBM’s Deep Blue). This will be the world’s largest neuromorphic supercomputer, with 228 trillion synaptic operations per second. This won’t be the fastest supercomputer in the world, which is currently reaching the exascale with quintillions of operations per second. So then what’s the big deal? It probably has something to do with the “neuromorphic” part.
The basic definition of a neuromorphic computer is one based on or inspired by the design of biological systems – something more closely resembling neurons and synapses. Conventional computers have central processing units and separate memory storage. But they seem to get the job done. Neuromorphic computers have components that function more like neurons and synapses which are both memory and processing at the same time. Also, the process is massively parallel and distributed. But if this is not necessarily faster than conventional computers, why bother?
There are two reasons, but the first is efficiency. The human brain is a powerful computer, and yet it operates only 20 watts of power. That is incredibly more energy efficient than any computer, and researchers believe this is because of the architecture. Right now specific computer applications use the energy of small countries. Crypto uses 127 terawatt hours per year, more than Norway. Data centers use 340 TWh. A Chat GPT query uses 15 times the energy as a normal Google query, and again is already getting to small-country levels of energy use. The AI revolution, whatever else you may think about it, is energy hungry.
