EAR  4.2.1
EAR Reference Manual
EAR-plug-ins

Some of the core of EAR functionality can be dynamically loaded through a plug-in mechanism, making EAR more extensible and dynamic than previous versions since it is not needed to reinstall the system to add, for instance, a new policy or a new power model. It is only needed to copy the file in the $EAR_INSTALL_PATH/lib/plugins folder and restart some components. The following table lists the current EAR functionalities designed with a plu-in mechanism:

Plug-in Description
Power model Energy models used by energy policies.
Power policies Energy policies themselves.
Energy readings Node energy readings.
Tracing Execution traces.
Report Data reporting.
Powercap Powercap management.

Considerations

Note SLURM Plugin does not fit in this philosophy, it is a core component of EAR and can not be replaced by any third party development.
