EARL is a runtime library automatically loaded with the applications and it offers
application metrics monitoring and it can select the frequencies based on the
application behaviour on the fly.
The Library is loaded automatically through the EAR Loader (EARLO) and it can be easly integrated with different system batch schedulers (e.g., SLURM). The EARL provides deep application accounting(both power/energy and performance) and energy optimization in a completelly transparent and dynamic way.

Visit the [architecture page](https://gitlab.bsc.es/ear_team/ear/-/wikis/Architecture) for a detailed description of each of these components.
The [user guide](User-guide) contains information about how to use EAR as an end user in a production environment.
The [admin guide](https://gitlab.bsc.es/ear_team/ear/-/wikis/Admin-guide) has all the information related to the installation and setting up, as well as all core components details.
Moreover, you can find a list of [tutorials](https://gitlab.bsc.es/ear_team/ear/-/wikis/Tutorials) about how to use EAR.
