The authors investigate the limit of voltage scaling together with task parallelization to maintain task-completion latency while reducing energy consumption. They examine improvements in energy efficiency and parallelism due to quickly boosting a core's operating voltage. When accounting for parallelization overheads, minimum task energy is obtained at near-threshold supply voltages across six commercial technology nodes and provides a roughly 4x improvement in overall CMP energy efficiency.
