GEOPM

Fine-grained low-latency batch access to power metrics and control knobs on Linux

Key Features

The Global Extensible Open Power Manager (GEOPM) provides a framework to explore power and energy optimizations on platforms with heterogeneous mixes of computing hardware.

Users can monitor their system’s energy and power consumption, and safely optimize system hardware settings to achieve energy efficiency and/or performance objectives.

With GEOPM, a system administrator can:

  • Grant per-user or per-group access to individual metrics and controls, even when their underlying interfaces do not offer fine-grained access control

  • Ensure that user-driven changes to hardware settings are reverted when the user’s process session terminates

  • Develop your own platform-specific monitor and control interfaces through the extensible plugin architecture

With GEOPM, an end user can:

  • Interact with hardware settings and sensors (e.g., set a CPU power limit or read a GPU’s current power consumption) using a platform-agnostic interface

  • Generate summarized reports of power and energy behavior during execution of an application

  • Automatically detect MPI and OpenMP phases in an application, generating per-phase summaries within application reports

  • Optimize applications to improve energy efficiency or reduce the effects of work imbalance, system jitter, and manufacturing variation through built-in control algorithms

  • Develop your own runtime control algorithms through the extensible plugin architecture

  • Gather large groups of signal-reads or control-writes into batch operations, often reducing total latency to complete the operations.
