org.cloudbus.cloudsim.provisioners.PeProvisionerSimple

All Implemented Interfaces:

PeProvisioner, ResourceProvisioner

public class PeProvisionerSimple
extends ResourceProvisionerSimple
implements PeProvisioner

A best-effort PeProvisioner policy used by a Host to provide virtual PEs to VMs from its physical PEs:

• if there is available MIPS on the physical PE, it allocates to a virtual PE;
• otherwise, it fails.

Each host's PE must have its own instance of a PeProvisioner. When extending this class, care must be taken to guarantee that the field availableMips will always contain the amount of free MIPS available for future allocations.

Since:

CloudSim Toolkit 2.0
