Linux energy aware scheduling

Nettet20. sep. 2024 · Energy Aware Scheduling (EAS) is an enhancement to Linux power management, unifying CPU power control under the Linux kernel. EAS extends the Linux kernel scheduler to make it fully aware of the power/performance capabilities of the CPUs in the system, to optimize energy consumption for advanced multi-core SoCs including … NettetEnergy Aware Scheduling (or EAS) gives the scheduler the ability to predict the impact of its decisions on the energy consumed by CPUs. EAS relies on an Energy Model (EM) of the CPUs to select an energy efficient CPU for each task, with a minimal impact on throughput. This document aims at providing an introduction on how EAS works, what …
