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： One embodiment of the present invention provides a system that mitigates the effects of multiple vibration sources on a set of hard disk drives (HDDs) within a computer system. During operation, the system identifies a target HDD in the set of HDDs, wherein the performance of the target HDD is affected by mechanical vibrations. The system also identifies one or more primary vibration sources from the multiple vibration sources that affect the performance of the target HDD. Next, for each of the primary vibration sources, the system measures a first time-domain signal associated with the operation of the primary vibration source using a first vibration transducer associated with the primary vibration source. The system also measures a second time-domain signal associated with the target HDD using a second vibration transducer associated with the target HDD. Next, for each of the primary vibration sources, the system then computes a cross-power-spectral-density (CPSD) between the first and the second time-domain signals. The system then selectively mitigates the primary vibration sources based on the CPSDs between the primary vibration sources and the target HDD.

摘要： One embodiment of the present invention provides a system that performs parallel grouping decomposition to facilitate expedited training of a support vector machine (SVM). During operation, the system receives a training dataset comprised of data vectors. The system then determines whether any data vector in the dataset violates conditions associated with a current SVM. Next, the system divides the violating data vectors into a number of subsets, thereby allowing parallel SVM training for each subset. The system subsequently builds an independent SVM for each subset in parallel based on the current SVM. The system then constructs a new SVM to replace the current SVM based on the SVMs built for each subset of violating data vectors.
