    摘要: A method for autonomous dynamic voltage (v) and frequency (f) scaling (DVFS) of a microprocessor, wherein autonomous detection of phases of high microprocessor workload and prediction of their duration is performed (PID). The microprocessor frequency (f) will be temporarily increased (LUT) to an appropriate safe value (even beyond its nominal frequency) consistent with technological and ambient constraints in order to improve performance when the computer system comprising the microprocessor benefits most, while during phases of low microprocessor workload its frequency (f) and voltage (v) will be decreased to save energy. This technique exploits hidden performance capabilities and improves the total performance of a computer system without compromising operational stability. No additional hardware such as service processors is needed for contemporary computer systems supporting performance counters and DFVS already. The invention allows significantly increasing the total computer system performance with only minimal impact on power (PMAX, PACTUAL) consumption.

    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 method and system for estimating processor utilization from power measurements provides an estimate of processor utilization that can be computed outside of the processor and operating system. Measurements of the processor power consumption are gathered over short intervals in a histogram. The idle power consumption of the processor is determined, and a threshold value higher than the idle power consumption level is computed from the idle power consumption. The number of histogram counts for bins greater than the threshold is normalized to the total number of measurements, providing a fractional value that corresponds to the processor utilization over the measurement interval. The fractional value can then be used in a power management algorithm that adjusts the frequency and optionally the voltage of the processor or group of processors based on their utilization.
