Planetary Scale Computing

Bernardo Huberman
HP Labs

About the talk:

The confluence of web technology, fast communication channels and internet data centers is leading to the emergence of planetary scale computing, in which diverse distributed applications will access the computing power of the planet as easily as drawing electricity from a plug. Besides the formidable obstacles one encounters to make it all happen, global utility computing poses the problem of how to deal with ever changing requirements, new additions, hidden resources and imperfect information on the part of both users and suppliers. I will show how an economics approach to these problems allows for the timely allocation of computing and storage resources to those who needed it, and the ensuing control problems that one encounters.

About the speaker:

Bernardo Huberman is an HP Fellow and Director of the Systems Research Center at Hewlett Packard Laboratories, where he also heads the research effort in Information Dynamics. He has worked in condensed matter physics, dealing with systems ranging from superionic conductors to two-dimensional superfluids, and has made contributions to the theory of critical phenomena in low dimensional systems. He is one of the discoverers of chaos in a number of physical systems, and also established a number of universal properties in nonlinear dynamical systems. His research into the dynamics of complex structures led to his discovery of ultradiffusion in hierarchical systems. He received his Ph.D. in Physics from the University of Pennsylvania, and is currently a Consulting Professor in the Department of Applied Physics at Stanford University.
