摘要： A mechanism is provided for scheduling application tasks. A scheduler receives a task that identifies a desired frequency and a desired maximum number of competing hardware threads. The scheduler determines whether a user preference designates either maximization of performance or minimization of energy consumption. Responsive to the user preference designating the performance, the scheduler determines whether there is an idle processor core in a plurality of processor cores available. Responsive to no idle processor being available, the scheduler identifies a subset of processor cores having a smallest load coefficient. From the subset of processor cores, the scheduler determines whether there is at least one processor core that matches desired parameters of the task. Responsive to at least one processor core matching the desired parameters of the task, the scheduler assigns the task to one of the at least one processor core that matches the desired parameters.

摘要： A mechanism is provided for controlling operational parameters associated with a plurality of processors. A control system in the data processing system determines a utilization slack value of the data processing system. The utilization slack value is determined using one or more active core count values and one or more slack core count values. The control system computes a new utilization metric to be a difference between a full utilization value and the utilization slack value. The control system determines whether the new utilization metric is below a predetermined utilization threshold. Responsive to the new utilization metric being below the predetermined utilization threshold, the control system decreases a frequency of the plurality of processors.

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 method, system, and computer program product for optimizing power consumption of an executing processor executing. The method includes determining a first sensitivity relationship (SR) based on a first and a second performance metric value (PMV) measured at a first and second operating frequency (OF), respectively. The first SR predicts workload performance over a range of OFs. A third OF is determined based on the first SR and a specified workload performance floor. A third PMV is measured by executing the processor operating at the third OF. A second SR based on the second and third PMVs is then determined. The first and second SRs are logically combined to generate a third SR. Based on the third SR, a fourth OF is outputted.
