| Name: | Henry Gordon Dietz |
| Position Type: | Chair |
| Appointment Start Date: | 01/01/00 |
| Appointment End Date: | |
| Area of Specialty: | Computer engineering. More specifically, interactions between and new technologies for compilers, computer architecture/hardware, and operating systems for high-performance computers. Over the past few years, this has broadened to also include digital imaging and sensor technologies as our emphasis has shifted to include embedded computing. |
| Summary Vita: | Henry Gordon Dietz ("Hank") earned his PhD from Polytechnic University and took a faculty position at Purdue University's School of Electrical and Computer Engineering in 1986. In 1999, he moved to the University of Kentucky's Department of Electrical and Computer Engineering, where he is a professor and the James F. Hardymon Chair in Networking. Dietz has authored over 150 publications, primarily involving compilers and computer architecture, and his research has been recognized by Gordon Bell and Computerworld Smithsonian awards. He has graduated 15 PhD students, regularly teaches both graduate and undergraduate courses, and was one of the three founders of the EPICS (Engineering Projects In Community Service) program. |
| Highest Degree: | Ph.D. |
| Professional Affiliations: | Member of IEEE, ACM, IS&T (Imaging Science & Technology). Program Committee Member, ICPP 2005. |
| Primary Research Focus: | Technologies that make the components of a computing system work better together. This centers on compilers, computer architecture/hardware, and operating systems work, but has expanded to also include a variety of technologies associated with digital imaging and sensor processing. |
| Key Contributions: | In 1994, we created the world's first Linux PC cluster supercomputer -- and we continue to be a major source of new software and hardware technologies improving the abilities and price/performance of supercomputers. Key contributions over the past year cenetered on Flat Neighborhood Networks (FNNs), methods for high-accuracy computing using GPUs, Warewulf cluster administration, and new compiler methods for register allocation and long-range prediction of power and thermal properties. |
