Mitigating the Power and Reliability Challenges in Multi-/Many-Cores
2nd floor, Room 204 , Georg-Schumann-Str. 7A , 01187 Dresden
As Moore’s law continues unabated, it is predicted that future generation many-cores will feature hundreds, and potentially even thousands, of cores that may be heterogeneous in their processing nature. Consequently, advancements in the chip manufacturing technology and increasing trends of application features have accelerated the growth of advanced computing architectures that need to meet performance-per-power, adaptivity, and reliability requirements.
Furthermore, high integration density of nano-scale transistors and roadblock on the voltage scaling result in increased power densities and temperatures on the chip. This leads to the emerging “Dark Silicon” problem, i.e., not all parts of the multi-many-core chip can be simultaneously powered-on at the nominal operating conditions for a given Thermal Design Power (TDP) constraint and cooling technology. High on-chip temperatures also worsen the reliability of multi-/many-cores.
This talk will provide a short introduction to power- and temperature related problems for on-chip systems. The emerging Dark Silicon problem is discussed along with critical research challenges. Afterwards, novel techniques to improve performance and reliability of multi-/many-cores under peak power and thermal constraints will be presented. Towards the end, this talk will provide a quick overview of other relevant research projects of my group.
Dr. Muhammad Shafique is a senior research group leader at the Chair for Embedded Systems (CES), Karlsruhe Institute of Technology (KIT), Germany. He received his Ph.D. in Computer Science from KIT in January 2011. Before, he was with Streaming Networks Pvt. Ltd. where he was involved in research and development of video coding algorithms, optimizations for VLIW-based Processors, and project management activities for three years. Dr. Shafique was a visiting research fellow at the School of Computer Science and Engineering, University of New South Wales (UNSW), Sydney, Australia in 2013 and at the Informatics Institute (INF), Federal University of Rio Grande do Sul (UFRGS), Porto Alegre, Brazil in 2012. His research interests are in power-efficient, reliable, and adaptive computing systems covering various design abstractions of the hardware and software stacks (like micro-architecture, architecture, run-time system, and compiler). Dr. Shafique is a principal investigator of the GetSURE and GetSURE-II projects in the German Research Foundation's (DFG) priority research program (SPP1500) on "Dependable Embedded Systems". He is also a member of the DFG-funded large-scale SFB-TR 89 “Invasive Computing” project. Besides that, he is leading (or has led) various research projects in the areas of low-power design, reliable computing, energy-efficient memory design and management, adaptive computing, and multi-/many-core systems. He has demonstrated success in leading team-projects, meeting project deadlines, motivating team members to peak performance levels, and completion of independent challenging tasks. His experience is corroborated by strong technical knowledge and an educational record (throughout Gold Medalist).
Dr. Shafique received 2015 ACM/SIGDA Outstanding New Faculty Award, 6 Gold Medals in educational career, CODES+ISSS 2015, 2014 and 2011 Best Paper Awards, DATE 2008 Best Paper Award, AHS 2011 Best Paper Award, DAC 2014 Designer Track Best Poster Award, ICCAD 2010 Best Paper Nomination, several HiPEAC Paper Awards, Best Master Thesis Award, and Best Elective Lecture Award for SS’14. He has (co)-authored 3 books, 3 book chapters and 120+ publications in premier journals and conferences. He is the TPC Co-Chair of 2016 and 2015 IEEE ESTIMedia, and has also served on the program committees of various premier IEEE/ACM conferences including ICCAD, DATE, CASES, ASP-DAC, FPL, etc. He is a member of the IEEE and IEEE Signal Processing Society (SPS). He holds one US patent.
