As we have seen in Chapter 8 the agent needs some information
from the SeD to make an optimal scheduling. This information is a performance
prediction of the SeD. The agent will ask the SeD to fill the data structure
defined in Chapter 8 with the information it needs. The SeD
returns the information and the agent can make the scheduling.
Performance prediction can be based on hardware information, the load of the SeD (the CPU load, the memory availability, etc.) or an advanced performance prediction can combine a set of basic performance predictions. A performance prediction scheduler module named CoRI is available.
CoRI is described in Section 9.2.
By default DIET is compiled with CoRI enabled. In table 9.1 you can see which information is available with each compilation option.
