HPLP work recognized as "ACM SIGARCH/IEEE-CS TCCA Influential ISCA paper award"

posted Apr 20, 2018, 6:43 AM by Xinfei Guo

The paper "Temperature-Aware Microarchitecture" HPLP students in collaboration with Prof. Skadron's students published 15 years ago was recently selected for the ACM SIGARCH/IEEE-CS TCCA Influential ISCA paper award! The award recognizes the paper from the ISCA proceedings 15 years earlier that has had the most impact on the field during the intervening years. This is a significant and richly deserved honor! Congratulations!

The full author list of the paper is: Skadron, Kevin, Mircea R. Stan, Wei Huang, Sivakumar Velusamy, Karthik Sankaranarayanan, and David Tarjan. The paper is available here https://ieeexplore.ieee.org/abstract/document/1206984/.

Xinfei and Prof. Stan's paper is awarded "Best in Session" at SRC TECHCON 2017 held in Austin, TX. Also another paper co-authored by Xinfei and Prof. Stan got the same award. TECHON is an annual industry conference for students funded by SRC to present their work. With over 400 attendees and 32 sessions at the conference, receiving this award is quite an achievement!

Here are information for both papers. 

X. Guo, M. Stan, "Deep Healing: Ease the BTI and EM Wearout Crisis by Activating Recovery," SRC TECHCON, Austin, TX, September 2017. (Session 20)
