PowerModelHostAbstract

public PowerModelHostAbstract()

Method Details

validatePower

protected static double validatePower(double power,
 String fieldName)

Checks if a power value (in Watts) is valid.

Parameters:

power - the value to validate (in Watts)

fieldName - the name of the field/variable storing the value

Returns:

the given power if it's valid

Throws:

IllegalArgumentException - when the value is smaller than 1

getPower

public final double getPower(double utilizationFraction)

Description copied from interface: PowerModelHost

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

Specified by:

getPower in interface PowerModelHost

Parameters:

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

Returns:

the power supply in Watts (W)

getPowerInternal

protected abstract double getPowerInternal(double utilizationFraction)

See Also:

• getPower(double)

setStartupPower

public PowerModelHost setStartupPower(double power)

Description copied from interface: PowerModelHost

Set the power consumed (in Watts) for starting up the Host.

Specified by:

setStartupPower in interface PowerModelHost

setShutDownPower

public PowerModelHost setShutDownPower(double power)

Description copied from interface: PowerModelHost

Set the power consumed (in Watts) for shutting down the Host.

Specified by:

setShutDownPower in interface PowerModelHost

addStartupTotals

public void addStartupTotals()

Description copied from interface: PowerModelHost

After the Host is powered on, adds the consumed power to the total startup power. If the Host is powered on/off multiple times, that power consumed is summed up.

Specified by:

addStartupTotals in interface PowerModelHost

addShutDownTotals

public void addShutDownTotals()

Description copied from interface: PowerModelHost

After the Host is powered off, adds the consumed power to the total shutdown power. If the Host is powered on/off multiple times, that power consumed is summed up.

Specified by:

addShutDownTotals in interface PowerModelHost
