Timothy M. Pinkston is an American computer engineer, researcher, educator and administrator whose work is focused in the area of computer architecture. He holds the George Pfleger Chair in Electrical and Computer Engineering and is a Professor of Electrical and Computer Engineering at University of Southern California (USC). He also serves in an administrative role as Vice Dean for Faculty Affairs at the USC Viterbi School of Engineering.[1]

Pinkston's computer architecture research focuses on the design of interconnection networks for many-core and multiprocessor computer systems. His research contributions span formal theory, methods, and techniques for abating interconnection network routing inefficiencies and preventing deadlock. He has contributed to development of solutions to network deadlocking phenomena, including routing-induced, protocol (message)-induced, and reconfiguration-induced deadlocks. He has also developed energy-, resource-, and performance-efficient network-on-chip (NoC) designs.[2]

In 2009, Pinkston became an IEEE Fellow (Institute of Electrical and Electronics Engineers) "for contributions to design and analysis of interconnection networks and routing algorithms."[3] In 2019, Pinkston became an ACM Fellow (Association for Computing Machinery) "for contributions to interconnection network routing algorithms and architectures, and leadership in expanding computing research.[4] Pinkston is the first African American to become a tenured faculty member with primary appointment in engineering and the first African American to hold a decanal administrative faculty position in engineering in USC's history.[5][6]

Education

[edit]

Pinkston earned a Bachelor of Science in Electrical Engineering in 1985 from Ohio State University. He then went on to earn an M.S. in Electrical Engineering in 1986 and a Ph.D. in Electrical Engineering in 1993, both from Stanford University.[1] The title of his Ph.D. thesis is The GLORI Strategy for Multiprocessors: Integrating Optics into the Interconnect Architecture.[7]

Career

[edit]

Prior to embarking on a professorial career in academia, Pinkston was a Member of Technical Staff at AT&T Bell Laboratories, a Research Intern at IBM T. J. Watson Research Laboratories, and a Hughes Doctoral Fellow and Research Staff at Hughes Research Laboratories (HRL). In 1993, Pinkston joined the University of Southern California as an Assistant Professor and promoted to the ranks of Associate Professor in 1999 and full Professor in 2003. From 2003 to 2005, he served as the Director of the Computer Engineering Division of Electrical Engineering-Systems at USC. In 2009, Pinkston was appointed as the Senior Associate Dean of Engineering of the USC Viterbi School of Engineering[8] and, in 2011, became the Vice Dean for Faculty Affairs in the Viterbi School.[9] In 2017, Pinkston was named holder of the Louise L. Dunn Endowed Professorship in Engineering,[10] and in 2019, he was named holder of the George Pfleger Chair in Electrical and Computer Engineering.[1]

At USC, Pinkston founded the Superior Multiprocessor Architecture (SMART) Interconnects Group which investigates high-performance communication architectures for parallel computer systems—interconnection networks, adaptive and reconfigurable routing algorithms, router design and implementation, and energy- and resource-efficient NoCs.[11] Pinkston was the lead co-author of "Interconnection Networks", a chapter appearing as Appendix E in the 4th edition and as Appendix F in the 5th and 6th editions of the textbook Computer Architecture: A Quantitative Approach.[12] He served as the founding Lead Program Director of the National Science Foundation’s Expeditions in Computing program in 2007–2008.[13] Before that, he served two years as NSF's CISE CCF Program Director for the Computer Systems Architecture area[14] and co-established the Multicore Chip Design and Architecture (MCDA) program, co-funded by SRC.[15]

Pinkston served as an Associate Editor of IEEE Transactions on Parallel and Distributed Systems (TPDS) from 1999 to 2002, a member of the Executive Committee of the IEEE Technical Committee on Computer Architecture (TCCA) from 2010–2015,[16] and a founding member of the SIGARCH/SIGMICRO Committee to Aid Reporting on Discrimination and Harassment Policy Violations (CARES) since 2018.[17]

Research

[edit]

In collaboration with his SMART group members, Pinkston conducted deadlock characterization studies that revealed how infrequently, and under what conditions, deadlocks can form and be resolved in interconnection networks, giving credence to deadlock recovery-based routing as a viable alternative to deadlock avoidance-based routing.[18] He and his collaborators investigated deadlock-free routing techniques that improve understanding of various approaches to resolve potential deadlocks, including regressive-based, deflective-based, and progressive-based recovery routing algorithms and architectures.[19][20][21]

Pinkston, with his collaborators, developed general theory for designing routing algorithms applicable to recovery-based as well as avoidance-based (preventative) approaches and developed a theoretical framework and design methodology for deadlock-free dynamic reconfiguration of routing algorithms—to tolerate network faults, hot-swapping, and other changes in interconnectivity that can cause reconfiguration-induced deadlocks—with minimal packet loss, high throughput, and improved resiliency.[22][23] Pinkston also led the development of design methodologies and router architectures for energy-, resource-, and performance-efficient on-chip networks (NoCs). With SMART group members, he was among the first to explore architectural support for effectively applying power-saving techniques, such as power gating, to NoCs for reducing static power consumption in computer systems.[24]

Philanthropy

[edit]

With an endowment gift from Pinkston, The Ohio State University has established the Pinkston Family Achievement Award Fund, which annually awards scholarships to students in the Lambda Psi minority engineering honorary who are performing at the highest academic levels, as well as to a Minority Engineering Program (MEP) student with the most-improved performance. It also supports Ohio State's Academic Coaching in Engineering (ACE) Program which offers tutoring and study strategy instruction to MEP students in OSU's College of Engineering.[25]
