The rise of dark silicon is driving a new class of architectural techniques that “spend” area to “buy” energy efficiency. In this talk I examine two new frameworks employed by computer architects to understand the challenges and opportunities that await us. The first is the utilization wall, a simple model that architects use to understand how technology scaling under post-Dennard assumptions will affect hardware design. The second framework is the four horsemen taxonomy that comprises four key approaches that future chip designers will use to attack the dark silicon problem. I will describe recent research projects that typify these approaches, including GreenDroid, a massively heterogeneous 28 nm processor being developed at UCSD. Finally, I conclude with some directions (and non-directions) that the human brain could offer for refactoring the computational stack for dark silicon.
Bio: I have been a professor in the Department of Computer Science and Engineering at the University of California, San Diego since 2005. I received a PhD in Electrical Engineering and Computer Science from MIT. I was lead architect of the 16-core MIT Raw tiled multicore processor, one of the earliest multicore processors, which was commercialized into the Tilera TILE64 architecture. I co-authored the earliest published research on dark silicon, including a paper that derives the utilization wall that causes dark silicon. More recently, I wrote the first academic paper on Bitcoin mining chips. My research on dark silicon fed into the ITRS 2008 report that led Mike Mueller of ARM to coin the term "dark silicon".
