The Global Extensible Open Power Manager (GEOPM) is a framework for exploring power and energy optimizations on heterogeneous platforms.
With GEOPM you can:
- Interact with hardware settings and sensors using a platform-agnostic interface
- Restore changes to hardware settings when configuring process terminates
- Profile applications to study their power and energy behavior
- Automatically detect MPI and OpenMP phases in an application
- Optimize MPI 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
The GEOPM repository supports two software packages: the
geopm-service
package and the geopm
package. The geopm-service
package provides a Linux systemd service. The geopm
package
provides a runtime for distrubted HPC applications.
-
A build of the
geopm-service
package is required to build and run thegeopm
HPC runtime -
All
geopm-service
package features may be used independently of the features provided by thegeopm
package -
All run and build requirements of the
geopm-service
package are provided by commony used Linux distributions -
The run and build requirements of the
geopm
package include several additional HPC specific dependencies
The files supporting the geopm-service
package are all within the
service
subdirectory located in the root directory of the the GEOPM
repository. Please refer to the service/README.rst
file for further
documentation about the GEOPM Service. Additionally a comprehensive
overview of the GEOPM service is posted here:
https://geopm.github.io/service.html
The geopm
package provides many built-in features. An advanced use
case is dynamically coordinating hardware settings across all compute
nodes used by an distributed HPC application in response to the
application's behavior and resource manager requests. The dynamic
coordination is implemented as a hierarchical control system for
scalable communication and decentralized control. The hierarchical
control system can optimize for various objective functions including
maximizing global application performance within a power bound or
minimizing energy consumption with marginal degradation of application
performance. The root of the control hierarchy tree can communicate
with the system resource manager to extend the hierarchy above the
individual MPI application and enable the management of system power
resources for multiple MPI jobs and multiple users by the system
resource manager.

We appreciate all feedback on our project. Please see our
contributing guide for how some guidelines on how to participate.
This guide is located in the root of the GEOPM repository in a file
called CONTRIBUTING.rst
. This guide can also be viewed here:

GEOPM is an open development project and we use Github to plan, review and test our work. The proccess we follow is documented here:
https://geopm.github.io/devel.html
this web page provides a guide for developers wishing to modify source
code anywhere in the GEOPM repository for both the geopm-service
and
the geopm
packages.
GEOPM version 2.0 provides a number of important changes since the
previous tagged release v1.1.0. Some of the most significant new
features are the GEOPM Service, support for Intel and NVIDIA GPUs, and
improved consistency of signal and control names provided by
PlatformIO. A wide range of other improvements have also been made,
including a higher performance profiling interface to support highly
parallel applications, and support for the isst_interface
driver.
This software is production quality as of version 1.0. We will be enforcing semantic versioning for all releases following version 1.0. Plese refer to the ChangeLog for a high level history of changes in each release. The test coverage report from gcov as reported by gcovr for the latest release are posted to our web page.
Some new features of GEOPM are still under development, and their
interfaces may change before they are included in official releases.
To enable these features in the GEOPM install location, configure
GEOPM with the --enable-beta
configure flag. The features currently
considered unfinalized are the endpoint interface, and the
geopmendpoint
application.
The GEOPM developers are very interested in feedback from the community. See the contributing guide to learn how to provide feedback.
