Package edu.kit.ipd.sdq.pcm.simulation.scheduler.exact.loaddistribution.balancers

Class ToThresholdBalancer

java.lang.Object

edu.kit.ipd.sdq.pcm.simulation.scheduler.exact.loaddistribution.balancers.AbstractLoadBalancer

edu.kit.ipd.sdq.pcm.simulation.scheduler.exact.loaddistribution.balancers.ToThresholdBalancer

All Implemented Interfaces:

ILoadBalancer

public class ToThresholdBalancer
extends AbstractLoadBalancer

Ensures that the load of two resource instances does not differ more than 'threshold'. The threshold is a relative value between 0 and 1. If 0 the load of both instances must be equal, if 1 the load of both instances is never balanced.

Method Detail

activelyBalance

public void activelyBalance(IResourceInstance instance)

Description copied from interface: ILoadBalancer

Balances the load. Two scenarios are possible. Either the load is balanced between all instances, or the specified instances pulls processes from the busiest one.

onFork

public void onFork(IResourceInstance instance)

onSleep

public void onSleep(IResourceInstance instance)

onTerminate

public void onTerminate(IResourceInstance instance)

onWake

public void onWake(IResourceInstance instance)
