Abstract
Power capping in computer clusters enables energy budgeting, efficient power delivery, and management of operational and cooling costs. Pack and Cap is a novel, practical methodology to select thread packing and dynamic voltage and frequency scaling (DVFS) configurations by learning multithreaded workload characteristics and adapting to dynamic-power caps. Pack and Cap improves energy efficiency and achievable range of power caps.
