Title: Codes for distributed computing

Prof.  Daniela Tuninetti, Ph.D.


University of Illinois Chicago; danielat@uic.edu

Session Highlights:

Since Shannon’s landmark paper, codes have been successfully employed at the physical layer of communications systems to detect or correct errors introduced by various channel impairments, such as random noise. In modern large-scale computing systems, the main problem is however not “noise” but the “distributed nature” of the data availability or of data processors. If “lack” of data at a node in a computing system is thought of as an “erasure,” then codes can come to the rescue. Erasure and network codes are expected to become critical components in distributed storage systems, in distributed computation systems, and in cache-aided systems. In those examples, codes effectively mitigate the effect of strugglers or reduce the communication loads in the data shuffling phase of distributed machine learning algorithms. They do so by carefully leveraging local storage capabilities/redundancy to create multicast opportunities in the communication data exchange phase (i.e., multicast means that the same transmission benefits simultaneously many workers). This talk will focus on the use of codes for speeding up computations in large distributed computing systems, and discuss interesting tradeoffs between distributed storage/cache space and download/delivery time.

About the speaker:

Dr. Daniela Tuninetti is currently a Professor within the Department of Electrical and Computer Engineering at the University of Illinois at Chicago (UIC), which she joined in 2005. Dr. Tuninetti got her Ph.D. in Electrical Engineering in 2002 from ENST/Telecom ParisTech (Paris, France, with work done at the Eurecom Institute in Sophia Antipolis, France), and she was a postdoctoral research associate at the School of Communication and Computer Science at the Swiss Federal Institute of Technology in Lausanne (EPFL, Lausanne, Switzerland) from 2002 to2004.  Dr. Tuninetti is a recipient of a best paper award at the European Wireless Conference in 2002, of an NSF CAREER award in 2007, and named UIC University Scholar in 2015.  Dr. Tuninetti was the editor-in-chief of the IEEE Information Theory Society Newsletter from 2006 to 2008, an editor for IEEE COMMUNICATION LETTERS from 2006 to 2009, for IEEE TRANSACTIONS ON WIRELESS COMMUNICATIONS from 2011 to 2014; and for IEEE TRANSACTIONS ON INFORMATION THEORY from 2014 to 2017.  Dr. Tuninetti’s research interests are in the ultimate performance limits of wireless interference networks (with special emphasis on cognition and user cooperation), coexistence between radar and communication systems, and multi- relay networks. Recently, she has worked on content-type coding, cache-aided systems and distributed coded computing.
