Information technology is now an indispensable pillar of a modern-day society, thanks to the proliferation of digital platforms in the past several decades. We are now witnessing two inflection points, however, that are about to change IT as we know it. First, we are entering the Big Data era where demand on robust and economical data processing, communication and storage is growing faster than technology can sustain. Second, 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 and eventually Dark Silicon. In this talk, I will motivate these two IT trends and present promising research avenues for server chip design including specialized scale-out processors, on-chip networks and die-stacked DRAM cache hierarchies.

个人简介: 是瑞士EPFL计算机系的教授,也是面向未来高能效与绿色云技术的EcoCloud研究中心的创始人与主任。Falsafi教授在计算机系统设计与评估方面做出了许多贡献,包括已经被Sun(现Oracle)采用的一种可扩展多处理体系结构、应用于IBM BlueGene/PBlueGene/QCache侦听过滤器以及流预取部件、已被AMD/HP研究与产品部门使用的系统模拟采样技术等。Falsafi教授最值得一提的工作是“发现现代系统中流行的多处理器内存编程模型——即内存一致性模型,对于提高计算性能既不必要也不充分”,这颠覆了传统的观点。最近几年Falsafi教授关注云计算技术,并因为云计算基准测试集CloudSuite相关工作获2012ASPLOS最佳论文奖。Falsafi教授获得了很多奖,包括NSF CAREER AwardIBM Faculty Partnership AwardAlfred P. Sloan Research Fellowship,同时也是IEEE Fellow
