Constructor Detail

ScheduledResource

public ScheduledResource(org.palladiosimulator.pcm.resourceenvironment.ProcessingResourceSpecification activeResource,
                         SimuComModel myModel,
                         String resourceContainerID,
                         String schedulingStrategyID)

Method Detail

createActiveResource

protected de.uka.ipd.sdq.scheduler.IActiveResource createActiveResource(SimuComModel myModel)

Description copied from class: AbstractScheduledResource

Subclasses are responsible for creating the IActiveResource to use internally. Is called in the constructor.

Specified by:

createActiveResource in class AbstractScheduledResource

Returns:

the IActiveResource resource to use as determined by the subclasses.

calculateDemand

protected double calculateDemand(double demand)

Description copied from class: AbstractScheduledResource

Template method. Implementers have to use the given demand and return the time span needed to process the demand on this resource.

Specified by:

calculateDemand in class AbstractScheduledResource

Parameters:

demand - The demand issued to this resource in units understood by the resource

Returns:

The service time, given in seconds

activateResource

public void activateResource()

Description copied from class: AbstractScheduledResource

Called by the framework to inform that the resource should start its lifecycle

Overrides:

activateResource in class AbstractScheduledResource

consumeResource

public void consumeResource(SimuComSimProcess process,
                            int resourceServiceID,
                            Map<String,Serializable> parameterMap,
                            double abstractDemand)

Description copied from class: AbstractScheduledResource

Called by client of this resource to make the resource simulate resource processing. This is the queueing network service center part of our simulation. Allows passing of additional parameters.

Specified by:

consumeResource in class AbstractScheduledResource

Parameters:

process - The thread or job requesting the processing of its demand

resourceServiceID - The id of the resource service to be called for resource consumption

parameterMap - Additional parameters which can be used by the resource. Map can be empty.

abstractDemand - The resource demand the client wishes to be processed by the resource

getRemainingDemandForProcess

public double getRemainingDemandForProcess(SimuComSimProcess thread)

Specified by:

getRemainingDemandForProcess in class AbstractScheduledResource

updateDemand

public void updateDemand(SimuComSimProcess thread,
                         double demand)

Specified by:

updateDemand in class AbstractScheduledResource

deactivateResource

public void deactivateResource()

Description copied from class: AbstractScheduledResource

Called by the framework to inform the resource that the simulation has been stopped. Fires a IStateListener#stateChanged() event.

Overrides:

deactivateResource in class AbstractScheduledResource

getNextResourceId

public static String getNextResourceId()

getScheduledResource

public de.uka.ipd.sdq.scheduler.IActiveResource getScheduledResource()

Specified by:

getScheduledResource in class AbstractScheduledResource

setProcessingRate

public void setProcessingRate(String newProcessingRate)

Method to alter processing rate at runtime, e.g., to model changing parameters of cloud environments at runtime

Parameters:

newProcessingRate - The new processing rate of this resource

getActiveResource

public org.palladiosimulator.pcm.resourceenvironment.ProcessingResourceSpecification getActiveResource()

getFailureTime

public double getFailureTime()

Returns the failure time for this resource (or -1.0 if the resource cannot fail).

Returns:

the failure time for the resource

getRepairTime

public double getRepairTime()

Returns the repair time for this resource (or -1.0 if the resource cannot fail).

Returns:

the repair time for the resource

update

public void update(long state,
                   int instanceId)

Specified by:

update in interface de.uka.ipd.sdq.scheduler.sensors.IActiveResourceStateSensor

Overrides:

update in class AbstractScheduledResource
