*Biosketch: * David Hilton Wolpert is an American mathematician,
physicist and computer scientist. He is a professor at Santa Fe
Institute. He is the author of three books, three patents, over one
hundred refereed papers, and has received numerous awards. His name is
particularly associated with a group of theorems in computer science
known as "no free lunch". Prof. Wolpert obtained a B.A. in Physics at
Princeton University (1984), then attended the University of California,
Santa Barbara, where he took the degrees of M.A. (1987) and Ph.D.
(1989). More information is available at: davidwolpert.weebly.com
*Abstract: *One of the central concerns of computer science is how the
resources needed to perform a given computation depend on that
computation. Moreover, one of the major resource requirements of
computers—ranging from biological cells to human brains to
high-performance (engineered) computers—is the energy used to run them,
i.e. the thermodynamic costs of running them. Those thermodynamic costs
of performing a computation have been a long-standing focus of research
in physics, going back (at least) to the early work of Landauer and
colleagues. However, one of the most prominent aspects of computers is
that they are inherently non-equilibrium systems. Unfortunately, the
research by Landauer and co-workers on the thermodynamics of computation
was done when non-equilibrium statistical physics was still in its
infancy, severely limiting the scope and formal detail of their
analyses. The recent breakthroughs in non-equilibrium statistical
physics hold the promise of allowing us to go beyond those limitations.
Here I present some initial results along these lines, concerning the
entropic costs of running (loop-free) digital circuits and Turing
machines. These results reveal new, challenging engineering problems for
how to design computers to have minimal thermodynamic costs. They also
allow us to start to combine computer science theory and stochastic
thermodynamics at a foundational level, thereby expanding both.
The talk (approx. 40 minutes) will be followed by a question/answer session.
