摘要： A processing node tracks probe activity level associated with its internal caching or memory system. If the probe activity level increases above a threshold probe activity level, the performance state of the processing node is increased above its current performance state to provide enhanced performance capability in responding to the probe requests. After entering the higher performance state in response to the probe activity level being above the threshold probe activity level, the processing nodes returns to a lower performance state in response to a reduction in probe activity. There may be multiple threshold probe activity levels and associated performance states.

摘要： A power allocation strategy limits performance of a subset of a plurality of computational units in a computer system according to performance sensitivity of each of the plurality of computational units to a change performance capability, e.g., frequency change. The performance of the subset of computational units may be limited by setting a power state in which the subset may be operated and/or reducing a current power state of the subset to a lower power state. The subset whose performance is limited includes computational units that are least performance sensitive according to stored sensitivity data. The subset may include one or more processing cores and performance of the one or more processing cores may be limited in response to a CPU-bounded application or graphics processing unit (GPU)-bounded application being executed.

摘要： Performance sensitivities to a change in performance capabilities of computational units of a computer system are determined based on measured utilization metrics for each of the computational units. In order to determine the performance sensitivities, in one approach, the computational units are operated at a first performance level, and respective first utilization metrics are determined. The computational units are then operated at a second performance level and respective second utilization metrics are determined. The sensitivity to performance capability change, e.g., a frequency change, is determined based on the respective first and second utilization metrics. The performance sensitivities of the computational units to a change in performance capability are continually updated in response to, e.g., a process context change of a computational unit or in response to a predetermined period of time elapsing since the last sensitivity to a performance capability change was determined for a computational unit.
