 This is a necessary phase prior to the normal EAR utilization and is a kind of hardware characterization of the nodes. During the phase a matrix of coefficients are calculated and stored. These coefficients will be used to predict the energy consumption and performance of each application.
 
 Please, visit the learning phase [wiki page](https://gitlab.bsc.es/ear_team/ear_learning/-/wikis/home) to read the manual and the [repository](https://gitlab.bsc.es/ear_team/ear_learning) to get the scripts and the kernels.
