H. J. Siegel is a Professor and Coordinator of the Parallel Processing Laboratory in the School of Electrical and Computer Engineering at Purdue University. He received from the Massachusetts Institute of Technology (MIT) B.S. degrees in both electrical engineering and management (1972), and from the Department of Electrical Engineering and Computer Science at Princeton University the M.A. (1974), M.S.E. (1974), and Ph.D. degrees (1977). Prof. Siegel has coauthored over 240 technical papers, has coedited seven volumes, and wrote the book Interconnection Networks for Large-Scale Parallel Processing (second edition 1990). He is a Fellow of the IEEE (Institute of Electrical and Electronics Engineers) professional society, was a Coeditor-in-Chief of the Journal of Parallel and Distributed Computing (1989-1991), and was on the Editorial Boards of the IEEE Transactions on Parallel and Distributed Systems (1993-1996) and the IEEE Transactions on Computers (1993-1996). He is an international keynote speaker and tutorial lecturer, as well as a consultant for government and industry.
Prof. Siegel's research interests include heterogeneous computing, parallel algorithms, interconnection networks, and the PASM reconfigurable parallel computer system. In the area of heterogeneous computing, he is examining ways to match segments of a task to different machines in a heterogeneous suite to exploit the varied computational capabilities available. His algorithm work explores the factors involved in mapping a problem onto a parallel processing system to minimize execution time. Topological properties and fault tolerance are the focus of his research on interconnection networks for large-scale parallel machines. He is analytically and experimentally investigating the utility of the three dimensions of dynamic reconfigurability supported by the PASM design ideas and the small-scale proof-of-concept prototype: mixed-mode parallelism, switchable inter-processor communications, and system partitionability. Agencies that have supported his research include the Air Force Office of Scientific Research, Army Research Office, Ballistic Missile Defense Agency, DARPA, Defense Mapping Agency, IBM, NASA, Naval Ocean Systems Center, Naval Research Laboratory, National Science Foundation, NRaD, Office of Naval Research, and Rome Laboratory.
Prof. Siegel was Chair of the IEEE Computer Society (IEEE-CS) Technical Committee on Computer Architecture (TCCA) in 1982 and Chair of the ACM (Association of Computing Machinery) Special Interest Group on Computer Architecture (SIGARCH) from 1983 to 1985. He was Program Co-Chair of the ``1983 International Conference on Parallel Processing'' (IEEE-CS co-sponsor), Program Chair of ``Frontiers `92: The 4th Symposium on the Frontiers of Massively Parallel Computation'' (1992, IEEE-CS and NASA sponsors), and Program Chair of the ``8th International Parallel Processing Symposium'' (1994, IEEE-CS sponsor). In addition, he has been General Chair/Co-Chair of four international conferences and Chair/Co-Chair of four workshops.
At Purdue, Prof. Siegel has co-developed a senior level course on systems programming, and graduate level courses on computer architecture, parallel processing, and parallel programming. He was an ``IEEE Computer Society Distinguished Visitor'' (1979-1982), giving invited lectures about his research, and is currently an ``ACM Lecturer.'' He is a member of the Eta Kappa Nu electrical engineering honorary society and the Sigma Xi science honorary society.
