Abstract

Information technology is now an indispensable pillar of a modern-day society, thanks to the proliferation of digital platforms in the past several decades. The demand on robust and economical data processing and storage, however, is growing faster than technology can sustain. Moreover, while forecasts indicate that chip density scaling will continue for another decade, the diminishing returns in supply voltage scaling and the impending “energy wall” is leading server designers towards energy-centric solutions. In this talk, I will motivate the end of energy scaling in servers from parallelism alone, and then project promising research avenues to help scale beyond existing chip architectures based on emerging cloud and data-center workloads.
