Wen-mei W. Hwu (S'78, M'88, F'98) received the PhD degree in computer science from the University of California, Berkeley. He is the Sanders-AMD Endowed Chair Professor at the Department of Electrical and Computer Engineering, University of Illinois at Urbana-Champaign. From 1997 to 1999, he served as the chairman of the Computer Engineering Program at the University of Illinois. His research interest is in the area of architecture, implementation, and software for high-performance computer systems. In particular, his research activities are focused around novel computer architectures and the compiler techniques required by these architectures. He is well-known for his contributions to the development of compiler technology for predicated execution and speculative execution in EPIC architectures. His recent work has mostly been in the area of deep program analysis and its applications to compiler transformations and advanced memory architectures. He is the director of the IMPACT lab ( www.crhc.uiuc. edu/Impact), which has delivered new compiler and computer architecture technologies to the computer industry since 1987. For his contributions to the areas of compiler optimization and computer architecture, he received the 1993 Eta Kappa Nu Outstanding Young Electrical Engineer Award, the 1994 Xerox Award for Faculty Research, the 1994 University Scholar Award of the University of Illinois, the 1997 Eta Kappa Nu Holmes MacDonald Outstanding Teaching Award, the 1998 ACM SigArch Maurice Wilkes Award, the 1999 ACM Grace Murray Hopper Award, and the 2001 Tau Beta Pi Daniel C. Drucker Eminent Faculty Award. He is a fellow of the IEEE and the ACM. He serves on the Executive Committees of the MARCO/DARPA C2S2 ( and GSRC ( wwww.gigascale. org) Focus Research Centers. He also serves on the GELATO Strategy Council (

Krishna V. Palem (S'80, M'86, F'04) has held a professorship in electrical and computer engineering and in computer science at the College of Computing, a senior research leadership in the College of Engineering, and has been the founding director of the Center for Research in Embedded Systems and Technology (CREST) ( at the Georgia Institute of Technology since 1999. He has worked with and led efforts internationally in the area of embedded systems, having founded one of the earliest laboratories for research in academia dedicated to this field in 1994—the Real-time Compilation Technologies and Instruction Level Parallelism (ReaCT-ILP) laboratory at the Courant Institute of Mathematical Sciences, New York University, where he was a tenured faculty member. The work pursued there led to the widely used TRIMARAN system ( www.trimaran. org), codeveloped with the CAR group of HP-Labs and the IMPACT project of the University of Illinois. From 1986 to 1994, he was a member of the IBM T.J. Watson Research Center. During this period, he met Bob Rau while he was serving as an advanced technology consultant to IBM's Santa Teresa Laboratory in the area of compiler optimizations. His efforts at the ReaCT-ILP laboratory were recognized with awards for excellence from Hewlett-Packard, IBM, and Panasonic. Another highlight of these research accomplishments is the award-winning dissertation of his PhD advisee, Suren Talla. As part of this research, Dr. Palem laid the foundations of architecture assembly which the prestigious Analysts' Choice Awards recognized by nominating it as one of the outstanding technologies of 2002. With Guang Gao, he started the Compilers, Architectures, and Synthesis for Embedded Systems (CASES) workshop series in 1998. Since then, this workshop has blossomed into a major international conference sponsored by ACM SIGs and the IEEETC, serving the community as a point of focus for quality research. He has chaired bodies whose advice has led to funding initiatives in embedded and hybrid systems in the US and overseas. He was a Schonbrunn visiting professor at the Hebrew University of Jerusalem, Israel, where he was recognized for excellence in teaching, and has held visiting positions at the National University of Singapore and the École Normale Supérieure in Paris. He is a fellow of the IEEE.
