GEOPM๏ƒ

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

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 systemโ€™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:๏ƒ

๐Ÿ” Utilize fine-grained access management
  • Grant per-user or per-group access to individual metrics and controls

  • Gain more granular management of features than the underlying OS access mechanisms provide

๐Ÿฆบ Provide safe access to hardware settings
  • Ensure that user-driven changes to hardware settings are reverted when the userโ€™s process session terminates

๐Ÿ—๏ธ Extend the open-core framework
  • Develop your own platform-specific monitor and control interfaces through the extensible plugin architecture

With GEOPM, an end user can:๏ƒ

๐Ÿ”ฌ Interact with hardware settings and sensors
  • Platform-agnostic interface

  • Support for a wide range of Linux device drivers

  • Examples: set a CPU power limit, read a GPUโ€™s current power consumption, limit the frequency range of system sub-components

โฑ๏ธ Measure application performance
  • 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

๐Ÿ Implement optimization objectives
  • 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

๐ŸŽ๏ธ Build fast efficient software
  • Gather large groups of signal-reads or control-writes into batch operations

  • Batch interface often reduces total latency to complete the operations
