An Australian lab is developing a neuromorphic supercomputer named Deep South, designed to mimic the human brain's structure and efficiency.

Summary

  • The supercomputer will physically resemble a human brain's neuron networks and perform about 228 trillion operations per second.
  • Neuromorphic computing, the paradigm behind this supercomputer, aims to model computers after brains, different from AI but sharing the concept of neuron networks.
  • The project focuses on how the brain can operate on low power, potentially leading to energy-efficient computing.
  • Deep South will use field-programmable gate arrays to simulate brain-like spiking and incorporate randomness in artificial neuron behavior.
  • The supercomputer is set to complete by April and will be accessible for research, with potential to operate much faster than the human brain.

Introduction to Neuromorphic Computing

0:00 - 37 sec

An Australian lab's supercomputer will resemble a human brain, performing many operations but still fewer than a real brain.

An Australian lab's supercomputer will resemble a human brain, performing many operations but still fewer than a real brain.

  • The supercomputer is being built at Western Sydney University, embracing neuromorphic computing.
  • The paradigm is distinct from AI, focusing on hardware that mimics the physical neuron networks.

Differences Between AI and Neuromorphic Computing

0:37 - 1 min, 7 sec

Neuromorphic computing diverges from AI by replicating the brain's physical network structure, not just the software.

Neuromorphic computing diverges from AI by replicating the brain's physical network structure, not just the software.

  • AI uses software to represent neuron networks, while neuromorphic computing aims to make the hardware resemble the brain's network.
  • Neuromorphic computers don't use biological tissue but emulate the brain's connectivity and functionality.

  • Some experiments use a random network of wires as a simple neuromorphic model.
  • IBM's True North processor, introduced in 2014, contains 1 million cores with neuron-like firing.

Deep South, named to reflect its Australian roots, will use field-programmable gate arrays to mimic neuron spiking and behavior.

Deep South, named to reflect its Australian roots, will use field-programmable gate arrays to mimic neuron spiking and behavior.

  • The supercomputer will be named Deep South, alluding to both its location and existing technology like Google's Deep Mind.
  • Field-programmable gate arrays will simulate neurons and incorporate randomness, a key brain characteristic.

The Objective of Building Deep South

4:26 - 55 sec

The project aims to understand the brain's power efficiency, not to create a super-powerful computer.

The project aims to understand the brain's power efficiency, not to create a super-powerful computer.

  • The goal is to learn how the brain operates on low power, which could inform energy-efficient computing.
  • Deep South will be slower to emulate the brain's speed, and completion is planned for April.
