Abstract
A mechanism is provided for reducing power consumed by a multi-core processor. Responsive to a number of properly functioning processor cores being more than a required number of processor cores in a multi-core processor, the power consumption measurement module determines a number of the properly functioning processor cores to disable. The power consumption measurement module initiates an equal amount of workload to be processed by each of the properly functioning processor cores. The power consumption measurement module determines power consumed by each of the properly functioning processor cores. The power consumption measurement module deactivates one or more of the properly functioning processor cores that have maximum power in order that the number of properly functioning processor cores deactivated is equal to the number of properly functioning processor cores to disable.
