Class ResourceControlOptimisationAlgorithm

java.lang.Object

eu.cactosfp7.cactoopt.optimisationservice.resourcecontrol.ResourceControlOptimisationAlgorithm

All Implemented Interfaces:

IOptimisationAlgorithm

public class ResourceControlOptimisationAlgorithm
extends Object
implements IOptimisationAlgorithm

The Optimisation Algorithm which encapsulated the resource control functionality. The algorithm is periodically called and expected to decide based on the current representation of the data center which resource control actions are supposed to be taken

Description copied from interface: IOptimisationAlgorithm

Run an optimization with the algorithm.

Specified by:

generateOptimizationPlan in interface IOptimisationAlgorithm

Parameters:

pdcm - Physical Data Centre Model.

ldcm - Logical Data Centre Model.

plm - Physical Load Model.

llm - Logical Load Model.

Returns:

An optimisation plan or null if no optimisation is suggested by the algorithm.
