摘要： A mechanism is provided for priority-based power capping. A power management controller identifies a set of priorities for a set of partitions of the data processing system. The power management controller determines whether a measured power of the data processing system exceeds a power cap for the data processing system. Responsive to the measured power exceeding the power cap, the power management controller sends a set of commands to a set of component actuators to adjust one or more of a set of operation parameters for a set of components associated with the set of partitions using the set of priorities. The set of component actuators adjust the one or more of the set of operational parameters associated with the set of component in order to reduce a power consumption of the data processing system.

摘要： A data processing system attributes energy consumption to individual program segments or threads includes a processor that executes a first thread during a first portion of a measurement interval and a second thread during a second portion of the interval. An energy monitor measures the total energy during the interval. Energy attribution code attributes a first amount of the total energy to the first thread and a second amount to the second thread based in part on the execution times of the threads. The code may define a range of possible energy values by determining maximum and minimum energy constraints for the threads. The invention may also be extended to a multiprocessor environment and to a simultaneous multithreading (SMT) processor. In addition, the process may be expanded to determine energy consumed by various peripheral units such as hard disk controllers and the like.

摘要： A method and system for decreasing power consumption in memory arrays having usage-driven power management provides decreased power consumption in the memory array of a processing system. Per-page usage information is gathered on memory by a memory controller and periodically evaluated by software. The software distinguishes between more frequently accessed pages and less frequently accessed pages by analyzing the gathered usage information and periodically migrates physical memory pages in order to group less frequently accessed pages and more frequently access pages in separately power-managed memory ranks. When used in conjunction with a usage-driven power management mechanism, the ranks containing the less frequently accessed pages can enter deeper power-saving states and/or any power-saving state for longer periods. Operation may be further enhanced by using packed allocation in the memory ranks containing the less-frequently accessed pages and scattered allocation in the memory ranks having more frequently accessed pages.

摘要： A performance control technique for a processing system that includes one or more adaptively-clocked processor cores provides improved performance/power characteristics. An outer feedback loop adjusts the power supply voltage(s) provided to the power supply voltage domain(s) powering the core(s), which may be on a per-core basis or include multiple cores per voltage domain. The outer feedback loop operates to ensure that each core is meeting specified performance, while the cores also include an inner feedback loop that adjusts their processor clock or other performance control mechanism to maximize performance under present operating conditions and within a margin of safety. The performance of each core is measured and compared to a target performance. If the target performance is not met for each core in a voltage domain, the voltage is raised for the voltage domain until all cores meet the target performance.

摘要： A method and system for real-time prediction of power usage for a change to another performance state provides input data for power management decision-making processes or for display to system operators. The unit(s) for which power usage is predicted may be a single processor in a uni-processor system or may extend up to the level of facilities within a complex of processing facilities. The method and system gather real-time data on the power consumption of the unit(s) and create a model, such as a regression model, of power versus performance. A resulting power usage change required by a prospective nominal performance state change is shown as display data, or is transmitted to a power budgeting controller to inform the controller as to potential changes that can enhance system operation, such as managing tradeoffs of power allocated to various sub-units of a processing system.

摘要： A histogram difference method and system for power/performance measurement and management has low data storage requirements while supporting multiple monitoring applications having different update rates. Histogram data for power usage and/or performance mode is collected at a predetermined rate and the histogram data is read out at periodic intervals by the monitoring applications. The monitoring applications subtract the histogram data from previously read histogram data set to determine a interval difference histogram. The minimum and maximum values for the interval are the lowest-valued and highest-valued bin in the interval difference histogram that have a count greater than zero. The average value for the interval is the mean of the interval difference histogram. A conservative bound of the maximum and minimum values for a system can be determined by adding the values of the maximum and minimum values determined for each subsystem in the system.

摘要： A method and system for power management including local bounding of device group power consumption provides the responsiveness of local power control while meeting global system power consumption and power dissipation limits. At the system level, a global power bound is determined and divided among groups of devices in the system so that local bounds are determined that meet the global system bound. The local bounds are communicated to device controllers associated with each group of devices and the device controllers control the power management states of the associated devices in the group to meet the local bound. Thus, by action of all of the device controllers, the global bound is met. The controllers may be memory controllers and the devices memory modules, or the devices may be other devices within a processing system having associated local controllers. Alternatively or in concert, the devices may be entire processing systems and the associated controller a power management controller for associated processing systems, whereby multiple processing locales may be power-managed consistent with a global power consumption budget.

摘要： A mechanism is provided for minimizing system power in the data processing system with fast convergence. A current aggregate system power value is determined using a current thermal threshold value. For each potential thermal threshold value in a set of potential thermal threshold values, a determination is made as to whether there is a potential thermal threshold value that results in a potential aggregate system power value that is lower than the current aggregate system power value. Responsive to identifying an optimal potential thermal threshold value from the set of potential thermal threshold values that results in minimum aggregate system power value that is lower than the current aggregate system power value, the optimal potential thermal threshold value is set as a new thermal threshold value.

摘要： A mechanism is provided for allocating energy budgets to a plurality of logical partitions. An overall energy budget for the data processing system and a total of a set of requested initial energy budgets for the plurality of partitions are determined. A determination is made as to whether the total of the set of requested initial energy budgets for the plurality of partitions is greater than the overall energy budget for the data processing system. Responsive to the total of the set of requested initial energy budgets exceeding the overall energy budget, an initial energy budget is allocated to each partition in the plurality of partitions based on at least one of priority or proportionality of each partition in the plurality of partitions such that a total of the initial energy budgets for the plurality of partitions does not exceed the overall energy budget of the data processing system.
