Title: Infusing Self-awareness into Turing Machine – A Path to Cognitive Distributed Computing

Abstract: Turing’s formulation of computation in terms of functions to process information using simple read, compute (change state) and write instructions combined with the introduction of program, data duality by von Neumann has allowed information technology (IT) to model, monitor, reason and control any physical system.  Many-core processors and virtualization technologies with on-demand resource provisioning, application agility and high-bandwidth communications have made web-scale services available anywhere at any time. However, as the scale of distributed systems increases, so does the limitation of the current computing model:

  •  Fluctuations play a major role: (for example, Google is experiencing “emergent behaviour” with their scheduling algorithms as the number of components increase).
  • As the computing workloads fluctuate wildly, attempts to improve resiliency of the services results in complexity. 70% of IT budget is consumed in assuring availability, performance and security
  • More importantly, current models of computation – Computationalism (based on Turing machine) and Connectionism (modelled after neural networks) both are inadequate to model cognitive processes involving dynamic coupling between various elements, where each change in one element continually influences every other element’s direction of change.

In this talk, we discuss a new autonomic computing approach that demonstrates self-management and the separation of resources and services without disturbing the current Turing machine implementations. The DIME network architecture (DNA) uses its non-von Neumann parallel implementation of a managed Turing machine with a signalling network overlay to address some of the limitations of both Computationalism and Connectionism. The architecture provides a mechanism for injecting sensors and actuators into a Turing Machine and allows implementing autonomic distributed computing where the computers and the programs they execute are orchestrated to achieve the overall intent while optimizing available computing resources. We present an implementation of cognitive cloud services that provides on-demand provisioning, self-repair, auto-scaling, live-migration and end-to-end service transaction security using a popular web services stack deployed across distributed servers (virtualized or not). The network of networks using the new computing, management and programming models allows modelling dynamic processes with intent and has profound implications to large scale distributed structures where the computer and the computed have to work in harmony to address inherent large-scale fluctuations.

Biography: Dr. Rao Mikkilineni received his PhD from University of California, San Diego in 1972 working under the guidance of prof. Walter Kohn (Nobel Laureate 1998).  He later worked as a research associate at the University of Paris, Orsay, Courant Institute of Mathematical Sciences, New York and Columbia University, New York. He is currently the Founder and Chief Scientist at C3 DNA Inc., California, a Silicon Valley start-up.  His past experience includes working at AT&T Bell Labs, Bellcore, U S West, several start-ups and more recently at Hitachi Data Systems. He currently chairs IEEE conference track on “Convergence of Distributed Clouds, Grids, and their Management” in WETICE2014. He has published more than fifty papers on topics from Greens Function Monte Carlo to POTS (Plain Old Telephone Service), PANS (Pretty Amazing New Services) using the Internet and SANs (Storage Area Networks). His book “Designing a New Class of Distributed Systems” was published in November 2011 by Springer Verlag, New York. It explores the viability of self-optimizing, self-monitoring autonomous non-von Neumann software systems. His recent paper on a new computing model for creating a new class of distributed computing services with the architectural resiliency of cellular organisms was published in the Turing centenary conference proceedings
