Abstract
Good engineering practice uses the characteristics of existing technologies to optimize implementation. Often, this will mean that design techniques optimal in a previous generation prove impractical or even unusable when a new technology becomes dominant. This rule is all too often forgotten, which we will demonstrate in two problems of computer design: Field-Programmable Gate Arrays (FPGA) and hardware prefetchers (providing the ability to fetch data early in anticipation of the need). FPGAs are extremely useful in mobile embedded systems where computing power and energy considerations are major concerns. Partial reconfiguration is often used to reduce power consumption when parts of the array are inactive, albeit at the cost of high energy overhead due to the large cost of transferring configuration information. Our study reveals that partial reconfiguration accelerates execution and reduces overall energy consumption by half. Second, we will demonstrate how increased transistor integration allows hardware prefetching to improve both energy-efficiency and performance.
Biography
Professor Jean-Luc Gaudiot received the Diplôme d'Ingénieur from the École Supérieure d'Ingénieurs en Electronique et Electrotechnique, Paris, France in 1976 and the M.S. and Ph.D. degrees in Computer Science from the University of California, Los Angeles in 1977 and 1982, respectively.
He is currently a Professor in the Electrical Engineering and Computer Science Department at the University of California, Irvine. He was Chair of the Department from 2003 to 2009. During his tenure, the department underwent significant changes. These include the hiring of twelve new faculty members (three senior professors) and the remarkable rise in the US News and World Report® rankings of the Computer Engineering program from 42 to 28 (46 to 36 for the Electrical Engineering program).
Prior to joining UCI in January 2002, he was a Professor of Electrical Engineering at the University of Southern California since 1982, where he served as Director of the Computer Engineering Division for three years. He has also designed distributed microprocessor systems at Teledyne Controls, Santa Monica, California (1979-1980) and performed research in innovative architectures at the TRW Technology Research Center, El Segundo, California (1980-1982). He frequently acts as consultant to companies that design high-performance computer architectures, and has served as an expert witness in patent infringement and product liability cases. His research interests include multithreaded architectures, fault-tolerant multiprocessors, and implementation of reconfigurable architectures. He has published over 200 journal and conference papers. His research has been sponsored by NSF, DoE, and DARPA, as well as a number of industrial organizations.
From 2006 to 2009, he was the first Editor-in-Chief of the IEEE Computer Architecture Letters, a new publication of the IEEE Computer Society, which he helped found to the end of facilitating short, fast turnaround of fundamental ideas in the Computer Architecture domain. From 1999 to 2002, he was the Editor-in-Chief of the IEEE Transactions on Computers. In June 2001, he was elected chair of the IEEE Technical Committee on Computer Architecture, and re-elected in June 2003 for a second two-year term. In 2009, he was elected to the Board of Governors of the IEEE Computer Society for a 3-year-term. He was the Chair of the IEEE Computer Society Publications Board Transactions Operations Committee (2010-2011), the Chair of the IEEE Computer Society Publications Board Magazines Operations Committee in 2012, the IEEE Computer Society vice President, Educational Activities Board in 2013, and is now the IEEE Computer Society vice President, Publications Board.
Dr. Gaudiot is a member of AAAS, ACM, and IEEE. He has also chaired the IFIP Working Group 10.3 (Concurrent Systems). He was co-General Chairman of the 1992 International Symposium on Computer Architecture, Program Committee Chairman of the 1993 IFIP Working Conference on Architectures and Compilation Techniques for Fine and Medium Grain Parallelism, the 1993 IEEE Symposium on Parallel and Distributed Processing (Systems Track), the 1995 Parallel Architectures and Compilation Techniques Conference (PACT ‘95), the High Performance Computer Architecture conference in 1999 (HPCA-5), and the 2005 International Parallel and Distributed Processing Symposium.
In 1999, he became a Fellow of the IEEE, “For Contributions to the Programmability and Reliability of Dataflow Architectures.” He was elevated to the rank of AAAS Fellow in 2007, “For Distinguished Contributions to the Design and Analysis of Highly Efficient Multiprocessor and Memory System Architectures.”
In his spare time, Dr. Gaudiot combines his passion for aviation with his love for teaching and he is an active flight instructor (both primary and instrument).
