All Implemented Interfaces:

IResourcePowerModelCalculator

public class LinearPowerModelCalculator
extends AbstractResourcePowerModelCalculator

Creates a calculator that evaluates the power consumption P of a PowerConsumingResource by interpolating between the resource's minimum P_min and maximum power consumption P_min using the utilization Util of the specific resource:

P = P_min + Util * (P_max - P_min)

Constructor Detail

LinearPowerModelCalculator

public LinearPowerModelCalculator(ResourcePowerBinding binding)

Create a calculator for a linear power model.

Parameters:

powerConsumingResource - The resource for which the calculator is created.

Method Detail

calculate

public org.jscience.physics.amount.Amount<javax.measure.quantity.Power> calculate(Collection<org.palladiosimulator.measurementframework.MeasuringValue> measurements)

Calculate the power consumption using a linear power model.

Specified by:

calculate in interface IResourcePowerModelCalculator

Specified by:

calculate in class AbstractResourcePowerModelCalculator

Parameters:

measurements - The MeasuringValues used for evaluation. More precisely, this calculator type requires that the collection contain at least one element of that represents a utilization measurement.
However, an empty collection is also valid: This is treated like a sole measurement that represents idleness (zero utilization).

Returns:

The evaluated power consumption.

getInputMetrics

public Set<org.palladiosimulator.metricspec.MetricDescription> getInputMetrics()

Description copied from interface: IResourcePowerModelCalculator

Returns the set of metrics for which this calculator needs measurements to be able to calculate the power consumption.

Specified by:

getInputMetrics in interface IResourcePowerModelCalculator

Specified by:

getInputMetrics in class AbstractResourcePowerModelCalculator

Returns:

The set of required metric descriptions.
