摘要： A mechanism is provided for oversubscribing branch circuits. An active energy management mechanism determines a cumulative wattage rating using power consumption information for a powered element, the power consumption information is for a primary and a redundant portion of the powered element. The active energy management mechanism determines a power reduction power cap to be used by the powered element in the event of a loss of either a primary or a redundant power source supplied to the powered element using the cumulative wattage rating, a branch circuit rating, and a circuit breaker rating for the powered element. The active energy management mechanism sends the power reduction power cap to the powered element in order that the powered element reduces power to the power reduction power cap in the event of the loss of either the primary power source or the redundant power source supplied to the powered element.

摘要： A mechanism is provided for dynamically power capping one or more units. A power capping mechanism sets a counter value corresponding to an initial energy budget assigned to a unit for a given interval. Responsive to the unit receiving an operation to perform during the given interval, the power capping mechanism decrements the counter value by a decrement value. Responsive to the given interval expiring, the power capping mechanism sends the counter value to a power control loop in the data processing system, receives a new energy budget from the power control loop, and resets the counter value to a value corresponding to the new energy budget assigned to the unit for a next interval.

摘要： A method and system for providing performance estimations for a specified power budget provides an indication of the impact on processing performance when closed-loop power/performance control is employed to meet the specified power budget. A workload, which may be the actual workload, or a test workload is run to determine actual power consumption at intervals during the execution of the workload. The power values are examined and if they exceed the specified budget, which may be one of multiple possible budget values, an estimate of the amount by and duration for which the closed-loop power/performance control would have to reduce the performance of the system for each interval in order to provide an estimate of actual performance for the budgetary level(s). The estimate is informed by tests of the workload at each power/performance level to provide a non-linear estimate of the relationship between performance and power for the particular workload.

摘要： A mechanism is provided for using a power proxy unit combined with on-chip actuators to meet a defined power target value identifying a target power consumption of a component of a data processing system. A power manager in the data processing system identifies a proxy power threshold value, for the defined power target value, identifying a maximum power usage for the component, and a power usage estimate value identifying a current power usage estimate for the component. The power manager sends a set of signals to one or more on-chip actuators in the power proxy unit associated with the component in response to the power usage estimate value being greater than the power proxy threshold value. The one or more on-chip actuators adjusts a set of operational parameters associated with the component in order to meet the defined power target value.

摘要： Accounting charges are assigned to workloads by measuring a relative use of computing resources by the workloads, then scaling the results using determined work-rate for the corresponding workload. Usage metrics for the individual resources may be selectable for the resources being measured and the work-rates may be determined from an analytical model or from empirical model that determines work-rates from an indication of processor throughput. Under single workload conditions on a platform, or other suitable conditions, a workload type may be used to select the particular usage metrics applied for the various resources.

摘要： An apparatus for providing system memory usage throttling within a data processing system having multiple chiplets is disclosed. The apparatus includes a system memory, a memory access collection module, a memory credit accounting module and a memory throttle counter. The memory access collection module receives a first set of signals from a first cache memory within a chiplet and a second set of signals from a second cache memory within the chiplet. The memory credit accounting module tracks the usage of the system memory on a per user virtual partition basis according to the results of cache accesses extracted from the first and second set of signals from the first and second cache memories within the chiplet. The memory throttle counter for provides a throttle control signal to prevent any access to the system memory when the system memory usage has exceeded a predetermined value.

摘要： Managing operations associated with one or more voltage changes and one or more frequency changes. A voltage change request and a frequency change request are associated with dynamic voltage and frequency scaling (DVFS) operations. The DVFS operations are transmitted by the processors to be executed by one or more direct current assemblies. A sequence associated with the one or more voltage changes and a sequence associated with the one or more frequency changes are detected by the system. The sequences are dynamically modified to enable insertion of an additional voltage change, whereby the additional voltage change indicates completion of one or more previous voltage change requests. Completion of the voltage change request enables one or more subsequent voltage change requests to be processed. When a voltage change request is not successfully completed one or more future voltage changes are suspended.
