Call me a hopeless romantic, but as I write Athis in late July, my money is on an amazing landing and a lifespan of successful discoveries emanating from this incred- ible scientific laboratory designed to measure everything from geology to bio-signatures past life has left behind. One thing is for sure, just like the moon landing back in the ’60s, I will be glued to the television (or maybe my iPad) as Curiosity makes its approach and landing on the surface of Mars.

    Summarizing CPU and GPU Design Trends with Product Data Yifan Sun, Nicolas Bohm Agostini, Shi Dong, and David Kaeli Northeastern University Email: fyifansun, agostini, shidong, [email protected] Abstract—Moore’s Law and Dennard Scaling have guided the products. Equipped with this data, we answer the following semiconductor industry for the past few decades. Recently, both questions: laws have faced validity challenges as transistor sizes approach • Are Moore’s Law and Dennard Scaling still valid? If so, the practical limits of physics. We are interested in testing the validity of these laws and reflect on the reasons responsible. In what are the factors that keep the laws valid? this work, we collect data of more than 4000 publicly-available • Do GPUs still have computing power advantages over CPU and GPU products. We find that transistor scaling remains CPUs? Is the computing capability gap between CPUs critical in keeping the laws valid. However, architectural solutions and GPUs getting larger? have become increasingly important and will play a larger role • What factors drive performance improvements in GPUs? in the future. We observe that GPUs consistently deliver higher performance than CPUs. GPU performance continues to rise II. METHODOLOGY because of increases in GPU frequency, improvements in the thermal design power (TDP), and growth in die size. But we We have collected data for all CPU and GPU products (to also see the ratio of GPU to CPU performance moving closer to our best knowledge) that have been released by Intel, AMD parity, thanks to new SIMD extensions on CPUs and increased (including the former ATI GPUs)1, and NVIDIA since January CPU core counts.

Advanced power management techniques for x86 processors are designed to reduce the power of underutilized cores while also allowing for dynamic allocation of the thermal budget between cores for improved performance.

  • Thermal Modeling and Management of Microprocessors
    Thermal Modeling and Management of Microprocessors A Dissertation Presented to the faculty of the School of Engineering and Applied Science University of Virginia In Partial Fulfillment of the requirements for the Degree Doctor of Philosophy Computer Science by Karthik Sankaranarayanan May 2009 Approvals This dissertation is submitted in partial fulfillment of the requirements for the degree of Doctor of Philosophy Computer Science Karthik Sankaranarayanan Approved: Kevin Skadron (Advisor) Jack W. Davidson (Chair) 7 Mircea R. Stan (Co-Advisor) James P. Cohoon John Lach Accepted by the School of Engineering and Applied Science: April 2009 Abstract The most recent, and arguably one of the most difficult obstacles to the exponential growth in transistor density predicted by Moore’s Law is that of removing the large amount of heat generated within the tiny area of a microprocessor. The exponential increase in power density and its direct relation to on-chip temperature have, in recent processors, led to very high cooling costs. Since temperature also has an exponential effect on lifetime reliability and leakage power, it has become a first-class design constraint in microprocessor development akin to performance. This dissertation describes work to address the temperature challenge from the perspective of the architecture of the microprocessor. It proposes both the infrastructure to model the problem and several mechanisms that form part of the solution. This research describes HotSpot, an efficient and extensible microarchitectural thermal modeling tool that is used to guide the design and evalua- tion of various thermal management techniques. It presents several Dynamic Thermal Management (DTM) schemes that distribute heat both over time and space by controlling the level of compu- tational activity.
