摘要： A system that controls one or more operating parameters in a computer system is presented. Until specified values for one or more operating parameters are achieved, the system performs the following operations. The system operates the computer system using a specified load profile. The system then determines whether the specified load profile produces the specified values for the one or more operating parameters. If the specified load profile does not produce the specified values for the one or more operating parameters, the system adjusts the specified load profile, which involves using a pulse-width modulation technique to adjust a duty cycle between a first workload and a second workload.

摘要： Embodiments of a computer system that includes a vibration-cancelling mode, and a related method and computer-program product (e.g., software) for use with the computer system, are described. During operation, a processor monitors operations in the computer system, and may select either the vibration-cancelling mode or an inactive mode based on the monitored operations. For example, the processor may select the vibration-cancelling mode when there are input/output-(I/O) intensive workloads to an array of one or more hard disk drives (HDDs) in the computer system. In this way, the processor may reduce the energy consumption associated with vibration-induced retries to the HDDs (and reduced I/O throughput) without increasing the energy consumption associated with active vibration damping at other times, such as when the computer system is idle or during processor-intensive workloads.

摘要： Some embodiments of the present invention provide a system that accurately synchronizes signals related to the operation of a computer system. During operation, the system receives a first time-domain signal associated with a first system variable and a second time-domain signal associated with a second system variable from the computer system. The system then transforms the first and the second time-domain signals into a first frequency-domain signal and a second frequency-domain signal, respectively. Next, the system computes a cross-power-spectral-density (CPSD) between the first and second frequency-domain signals to obtain a phase angle versus frequency graph between the two frequency-domain signals. The system subsequently extracts the slope of the phase angle versus frequency graph, and uses the value of the slope to synchronize the first time-domain signal and the second time-domain signal.
