Power Management (Powersched)
Powersched
Powersched proposes a reliable, efficient, and transparent mechanism to keep a HPC system under a power cap. The tool aims to increase the energy efficiency of available resources by enabling dynamic power capping based on an application-specific, energy-optimized runtime environment. Powersched can dynamically set a power cap for corresponding job nodes based on the application’s behavior at runtime. The power capping here is appied dynamically and will adapt to different application phases. Depending on the job characteristic we aim for an improvement in energy efficiency of order 20% with a moderate performance impact (or gain) of order 5%.
