Method Details

getMaxPower

public double getMaxPower()

Description copied from interface: PowerModel

Gets the max power that can be supplied by the host in Watts (W).

Returns:

the max power supply in Watts (W)

getPowerInternal

protected double getPowerInternal(double utilization) throws java.lang.IllegalArgumentException

Description copied from class: PowerModelAbstract

An internal method to be implemented by sub classes to get the power supply for the current CPU utilization.

The basic parameter validation is performed by the PowerModelAbstract.getPower(double) method.

Specified by:

getPowerInternal in class PowerModelAbstract

Parameters:

utilization - the utilization percentage (between [0 and 1]) of a resource that is critical for power supply.

Returns:

the power supply for the given CPU utilization

Throws:

java.lang.IllegalArgumentException - when the utilization percentage is not between [0 and 1]

getPowerData

protected abstract double getPowerData(int index)

Gets the power consumption for a given utilization percentage.

Parameters:

index - the utilization percentage in the scale from [0 to 10], where 10 means 100% of utilization.

Returns:

the power consumption for the given utilization percentage
