Overview of the learning phase
|
|
|
|
------------------------------
|
|
|
|
This is a phase prior to the normal EAR utilization, and it is called learning phase since is a kind of hardware characterization of the nodes.
|
|
|
|
|
|
|
|
During the learning phase a matrix of coefficients are computed and stored on all nodes. This coefficients next to some measurements, are used to predict the performance and energy costs of each repetitive sections of each application. To computed them, a set of stress tools (or kernels), are included in this package and are executed for a selected range of system frequencies.

|
A set of scripts to simplify the learning phase is provided in the `scripts` folder. It is also included the code of these stressing tools in the folder `kernels`. |
