Constructor Details

PowerModelHostSimple

public PowerModelHostSimple(double maxPower,
double staticPower)

Instantiates a PowerModelHostSimple by specifying its static and max power usage.

Parameters:

maxPower - power (in watts) the host consumes under full load.

staticPower - power (in watts) the host consumes when idle.

Method Details

getPowerMeasurement

public PowerMeasurement getPowerMeasurement()

Description copied from interface: PowerModel

Returns the entity's current power usage as a PowerMeasurement, which can hold additional information like static and dynamic fraction of power usage.

getPower

public double getPower(double utilizationFraction)
                throws IllegalArgumentException

Computes the hosts power usage in Watts (W) at a certain degree of utilization. Mainly for backwards compatibility.

Specified by:

getPower in class PowerModelHost

Parameters:

utilizationFraction - the utilization percentage (between [0 and 1]) of the host.

Returns:

the power supply in Watts (W)

Throws:

IllegalArgumentException - if utilizationFraction is not between [0 and 1]

getMaxPower

public double getMaxPower()

Gets the maximum power (in watts) the host consumes under full load.

Returns:

getStaticPower

public double getStaticPower()

Gets the static power (in watts) the host consumes when idle.

Returns:
