Background papers
Is Dark Silicon Useful? by M. Bedford Taylor. The ACM Digital Library.
Toward Dark Silicon in Servers, by N. Hardavellas, et al.
Web Search Using Mobile Cores, by V. Janapa Reddi, et al. The ACM Digital Library.
Abstract:
The popularity of online services drives need for bigger datacenters with more server processors. As Moore's law continues, the number of transistors on chip rises exponentially, enabling us to have CMPs with hundreds of cores. However, due to the breakdown of Dennard's scaling, we cannot power up all of them at the same time. Hence, soon we will enter an era of "dark silicon", in which we cannot power up our fast and dense processors. In this work, we explore the potential directions to improve energy efficiency of server processors in the post-Dennard era. Moreover, we investigate the hardware- and software-related constraints of designing a server processor for modern cloud services, and we propose an approach to design energy efficient server processors.
