Power-Capping Strategies

Elektron is capable of deploying different power capping strategies. The power capping strategy to be plugged in can be specified using the -powercap command-line option.

Power-Capping Policies

  • Extrema - A dynamic power-capping strategy that is able to make smart trade-offs between makespan and power consumption. Extrema reacts to power trends in the cluster and restrains the power consumption of the cluster to a power envelope defined by a high threshold and low threshold.
  • Progressive-Extrema - A modified version Extrema that performs power-capping in phases. Unlike in Extrema, where picking a previously capped node as a victim resulted in a NO-OP, Progressive-Extrema applies a harsher capping value for that victim.
