摘要： A system for post-silicon leakage characterization is configured to apply a rail voltage to a hardware component; cause the hardware component to operate at a particular frequency; cause a cooling device, coupled to the hardware component, to operate at a cooling capacity; run a workload on the hardware component after applying the rail voltage, causing the hardware component to operate at a particular frequency, and causing the cooling device to operate at a particular cooling capacity; discontinue the workload and clocks of the hardware component after a temperature of the hardware component has reached a steady high point; continuously measure temperature and leakage power of the hardware component after discontinuing the workload until the temperature of the hardware component has reached a steady low point; and adjust a power management procedure for the hardware component based on measured temperature and measured leakage power of the hardware component.

摘要： Adaptive power capping in a chip that includes a plurality of cores in a processing system is provided. An active power demand for the chip is dynamically determined based on observed events of the cores. An average temperature of the chip is computed using one or more on-chip thermal sensors in the cores to estimate leakage power of the chip. A power capping threshold that incorporates the estimate of leakage power is determined based on the average temperature of the chip. Power capping is performed by throttling the cores based on determining that the active power demand for the chip exceeds the power capping threshold.

摘要： A method for adjusting a frequency of a processor is disclosed herein. In one embodiment, the method includes determining a total current and a temperature of the multi-core processor and estimating a leakage current for the multi-core processor. The method also includes calculating a switching current by subtracting the leakage current from the total current. The method also includes calculating an effective switching capacitance based at least in part on the switching current. The method also includes calculating a workload activity factor by dividing the effective switching capacitance by a predetermined effective switching capacitance stored in vital product data, and enforcing a turbo frequency limit of the multi-core processor based on the workload activity factor.

摘要： A method includes monitoring power usage for a storage system that includes a set storage units at a first level of storage granularity and a set of storage sub-units at a second level of storage granularity, wherein the second level of storage granularity is finer than the first level of storage granularity. The method further includes assigning a non-uniform power budget to the set of storage units and adjusting a power budget for the storage sub-units according to the non-uniform power budget assigned to the storage units. A corresponding computer program product and computer system are also disclosed herein.

摘要： A mechanism is provided for implementing an operational parameter change within the data processing system based on an identified degradation. One or more degradations existing in the data processing system are identified based on a set of degradation values obtained from a set of degradation sensors. A determination is made as to whether one or more operational parameters need to be modified based on the one or more identified degradations. Responsive to determining that the one or more operational parameters need to be modified based on the one or more identified degradations, an input change is implemented to a one or more control devices in order that the one or more operational parameters are modified.

摘要： A mechanism is provided for power capping power consumption devices with multiple power supplies. A set of power supplies supplying power to a power consumption device having stranded power is determined. A power budget of one or more power supplies in the set of power supplies is adjusted to match a power budget of a power supply in the set of power supplies with a limiting power budget among the power budgets computed for each power supply in the set of power supplies. Responsive to identifying at least one power supply in the one or more other power supplies of one or more different power consumption devices having an initially allocated power budget below their corresponding demand, at least a portion of the stranded power is allocated to the power budget of the at least one power supply.
