  1. ; (, USENIX Hot Carbon)
    Traditional datacenter design and optimization for TCO and PUE is based on static views of power grids as well as computational loads. Power grids exhibit increasingly variable price and carbon-emissions, becoming more so as government initiatives drive further decarbonization. The resulting opportunities require dynamic, temporal metrics (eg. not simple averages), flexible systems and intelligent adaptive control. Two research areas represent new opportunities to reduce both carbon and cost in this world of variable power, carbon, and price. First, the design and optimization of flexible datacenters. Second, cloud resource, power, and application management for variable-capacity datacenters. For each, we describe the challenges and potential benefits.

  2. ; (, PEARC '22: Practice and Experience in Advanced Research Computing)
    After a long period of steady improvement, scientific computing equipment (SCE, or HPC) is being disrupted by the end of Dennard scaling, the slowing of Moore's Law, and new challenges to reduce carbon, to fight climate change. What does this mean for the future? We develop a system and portfolio model based on historical NSF XSEDE site systems and apply it to examine potential technology scenarios and what they mean for future compute capacity, power consumption, carbon emissions, datacenter siting, and more.
