Panel: Beyond Von Neumann, Neuromophic Systems and Architectures

On November 21, 2014, at Supercomputing 2014, I participated in a panel on "Beyond Von Neumann, Neuromophic Systems and Architectures" organized by Mark E. Dean along with R. Jacob Vogelstein, Karlheinz Meier, Kris Carlson, and Dhireesha Kudithipudi.

Supercomputing 2014

This week, IBM and Cornell team presented a ACM Gordon Bell Prize Finalist paper at Supercomputing 2014:

Title: "Real-time Scalable Cortical Computing at 46 Giga-Synaptic OPS/Watt with 100× Speedup in Time-to-Solution and 100,000× Reduction in Energy-to-Solution".

Abstract: Drawing on neuroscience, we have developed a parallel, event-driven kernel for neurosynaptic computation, that is efficient with respect to computation, memory, and communication. Building on the previously demonstrated highly-optimized software expression of the kernel, here, we demonstrate TrueNorth, a co-designed silicon expression of the kernel. TrueNorth achieves five orders of magnitude reduction in energy-to- solution and two orders of magnitude speedup in time-to-solution, when running computer vision applications and complex recurrent neural network simulations. Breaking path with the von Neumann architecture, TrueNorth is a 4,096 core, 1 million neuron, and 256 million synapse brain-inspired neurosynaptic processor, that consumes 65mW of power running at real-time and delivers performance of 46 Giga-Synaptic OPS/Watt. We demonstrate seamless tiling of TrueNorth chips into arrays, forming a foundation for cortex-like scalability. Unprecedented time-to-solution, energy-to-solution, scale, and performance of TrueNorth, combined with underlying flexibility of the kernel enables a broad range of cognitive applications.

The long-term aspiration is to build a "1%-human-scale" system with 4,096 processors one trillion synapses and that consumes merely 4kW.

Cognitive Systems Colloquium

On May 10-11, 2006, I chaired IBM's Almaden Institute on Cognitive Computing. The Institute brought together over 165 attendees from over 57 different institutions and featured prominent speakers and panelists: Nobelist Gerald Edelman, The Neurosciences Institute, Henry Markram, EPFL/BlueBrain, Robert Hecht-Nielsen, UCSD, Jeff Hawkins, Palm/Numenta, James Albus, NIST, Theodore Berger, USC, Kwabena Boahen, Stanford, Ralph Linsker, IBM, Jerry Swartz, The Swartz Foundation, V. S. Ramachandran, UCSD, John Searle, UC Berkeley, Joaquin Fuster, UCLA, Leslie Valiant, Harvard University, Toby Berger, University of Virginia, and Christof Koch, Caltech.

Today, 8.5 years later, I chaired IBM's Cognitive Systems Colloquium with the goal of Taking Brain-Inspired Computing to Market. The Colloquium gathered over 200 eminent, innovative thinkers from academia, government, industry, research and the media.

Here are speakers and panelists:

  • Andreas Andreou, Johns Hopkins
  • Dharmendra S Modha, IBM Fellow, IBM Chief Scientist, Brain-Inspired Computing
  • Fei-Fei Li, Director, AI Lab, Stanford University
  • Gary Marcus, NYU
  • Gill Pratt, DARPA SyNAPSE Program Manager
  • Horst Simon, Deputy Director, Lawrence Berkeley National Lab
  • Karlheinz Meier, Co-Director, Human Brain Project, U. Heidelberg
  • Mark Anderson, Future in Review and Strategic News Service
  • Michael Hawrylycz, Allen Institute for Brain Science
  • Miyoung Chun, Executive VP of Science Programs, Kavli Foundation
  • Rajit Manohar, Cornell University, Associate Dean
  • Richard Cytowic, Author of Synesthesia: A Union of the Senses
  • Jayashree Subrahmonia, Vice President, Products, IBM Watson Group
  • Tobi Delbruck, Co-Founder, iniLabs & Professor, ETH
  • Vijaykrishnan Narayanan, PI, NSF Expeditions in Computing, Professor, Penn State

The Colloquium also included a SyNAPSE Deep Dive that covered: TrueNorth Architecture, TrueNorth Neuron Model, TrueNorth Chip with 1 million neurons and 256 million synapses, Single Chip Board, 16 chip Board, Future Scaling Path, TrueNorth "program", Compass Simulator, Corelet Programming Language, SyNAPSE University, and Demos.

Videos from the event will be available in the near future. Here is a summary.
