Multicore Model from Abstract Single Core Inputs
Found in: IEEE Computer Architecture Letters
By Emily Blem,Hadi Esmaeilzadeh,Renee St. Amant,Karthikeyan Sankaralingam,Doug Burger
Issue Date:July 2013
pp. 59-62
This paper describes a first order multicore model to project a tighter upper bound on performance than previous Amdahl's Law based approaches. The speedup over a known baseline is a function of the core performance, microarchitectural features, applicatio...
 
Dark Silicon and the End of Multicore Scaling
Found in: IEEE Micro
By Hadi Esmaeilzadeh,Emily Blem,Renee St. Amant,Karthikeyan Sankaralingam,Doug Burger
Issue Date:May 2012
pp. 122-134
A key question for the microprocessor research and design community is whether scaling multicores will provide the performance and value needed to scale down many more technology generations. To provide a quantitative answer to this question, a comprehensi...
 
Power struggles: Revisiting the RISC vs. CISC debate on contemporary ARM and x86 architectures
Found in: 2013 IEEE 19th International Symposium on High Performance Computer Architecture (HPCA)
By Emily Blem,Jaikrishnan Menon,Karthikeyan Sankaralingam
Issue Date:February 2013
pp. 1-12
RISC vs. CISC wars raged in the 1980s when chip area and processor design complexity were the primary constraints and desktops and servers exclusively dominated the computing landscape. Today, energy and power are the primary design constraints and the com...
 
Power challenges may end the multicore era
Found in: Communications of the ACM
By Doug Burger, Emily Blem, Hadi Esmaeilzadeh, Karthikeyan Sankaralingam, Renée St. Amant
Issue Date:February 2013
pp. 93-102
Starting in 2004, the microprocessor industry has shifted to multicore scaling---increasing the number of cores per die each generation---as its principal strategy for continuing performance growth. Many in the research community believe that this exponent...
     
Power Limitations and Dark Silicon Challenge the Future of Multicore
Found in: ACM Transactions on Computer Systems (TOCS)
By Doug Burger, Emily Blem, Hadi Esmaeilzadeh, Karthikeyan Sankaralingam, Renée St. Amant
Issue Date:August 2012
pp. 1-27
Since 2004, processor designers have increased core counts to exploit Moore’s Law scaling, rather than focusing on single-core performance. The failure of Dennard scaling, to which the shift to multicore parts is partially a response, may soon limit ...
     
Dark silicon and the end of multicore scaling
Found in: Proceeding of the 38th annual international symposium on Computer architecture (ISCA '11)
By Doug Burger, Emily Blem, Hadi Esmaeilzadeh, Karthikeyan Sankaralingam, Renee St. Amant
Issue Date:June 2011
pp. 365-376
Since 2005, processor designers have increased core counts to exploit Moore's Law scaling, rather than focusing on single-core performance. The failure of Dennard scaling, to which the shift to multicore parts is partially a response, may soon limit multic...
