Powersched
Powersched (HPE) 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 power capping based on an application-specific, energy-optimized runtime environment. The power capping is governed by the Golden-Section-Search (GSS) optimization of a given metric (a variant of the Energy-Delay-Product) 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%.
A summary is included below.
Golden Section Search (GSS)
Dynamic power capping (per socket). As a corollary you might observe a relaxation period especially during startup and in changing application phases.
