Jan 4, 2012 Flexible coding schemes with applications to emerging memory technologies Lara Dolecek, UCLA American Mathematical Society Annual Meeting 2012 In this talk co-PI Lara Dolecek discussed a novel class of non-binary coding schemes for a channel model arising in emerging memory technologies. Dec 22, 2011 Exploiting Unreliable Embedded Memories Nikil Dutt International Symposium on Electronic System Design (ISED 2011) With co-author Luis A.D. Bathen, UC Irvine PI Nikil Dutt surveyed a serioes of hardware and software schemes that both ameliorate poor reliability, and exploit unreliable embedded memories through hardware and software mechanisms in order to achieve a low-power, fault-tolerant memory space, and keep production yield at tolerable levels. Dec 19, 2011 Exploiting Errors for Low Power On-Chip Memories Nikil Dutt, UC Irvine International Symposium on Electronic System Design (ISED) 2011 This plenary keynote speech was delivered at ISED 2011 in Kochi, India.

Presentation Materials: Download Oct 13, 2011 Memory Virtualization and Security for Embedded Systems Nikil Dutt, UC Irvine Workshop on Embedded Systems Security (WESS) 2011 This talk was presented at WESS 2011 in Taipei, Taiwan. Sep 18, 2011 Invited Lecture Subhasish Mitra, Stanford University IEEE International Test Conference 2011 Dr. Mitra delivered this lecture in Anaheim, Calif. Aug 11, 2011 Extending Flash Memory Lifetime Using Coding Techniques Ryan Gabrys, UCLA Flash Memory Summit This invited talk by UCLA grad student Ryan Gabrys was co-authored by Variability co-PI Lara Dolecek. The conference took place in San Jose, CA, and the talk led to several industry contacts. Aug 3, 2011 OS-Level Power Minimization Under Tight Performance Constraints in General-Purpose Systems Raid Ayoub, UC San Diego Intl Symposium on Low Power Electronics and Design (ISLPED 2011), Fukuoka, Japan The authors propose a new DVFS algorithm for enterprise systems that elevates performance as a first order control parameter and manages frequency and voltage as a function of performance requirements. Their algorithm is implemented on real Intel Westmere platform in Linux and they demonstrate its ability to reduce the standard deviation from target performance by more than 90% over state of the art policies while reducing average power by 17%. Presentation Materials: Download Jul 2, 2011 Robust Systems for Scaled CMOS and Beyond Subhasish Mitra, Stanford University IFIP Working Group 10.4 Dependable Computing and Fault Tolerance The meeting took place in Taoyuan, Taiwan. Presentation Materials: Download Jun 15, 2011 Evaluating the Effectiveness of Model-Based Power Characterization Yuvraj Agarwal, UC San Diego USENIX Annual Technical Conference (USENIX ATC 2011) At USENIX ATC 2011 in Portland, Oregon,the Variability Expedition Executive Director Yuvraj Agarwal will report on completed instrumentation of a server platform (Intel Willowbrook) and two mobile platforms (Intel Calpella and Sandybridge) for detailed power measurements. In experiments with the identical base calpella system but two instances of the same core i5-540 processor, the UCSD research team measured a 13 percent variability in power consumption for the same benchmarks with everything else kept constant. |
