Abstract:
1. A method, in a data processing system, for reducing power consumed by a multi-core processor, the method comprising: determining, by a power consumption measurement module, whether a number of properly functioning processor cores in the multi-core processor is more than a required number of processor cores for the multi-core processor; responsive to the number of properly functioning processor cores being more than the required number of processor cores, determining, by the power consumption measurement module, a number of the properly functioning processor cores to disable; initiating, by the power consumption measurement module, an equal amount of workload to be processed by each of the properly functioning processor cores; determining, by the power consumption measurement module, power consumed by each of the properly functioning processor cores; and deactivating, by the power consumption measurement module, 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.
