Technologies pertaining to compressing time-series signals are described herein. Groups of time-series signals are generated based upon similarities between time-series signals. Each group of time-series signals includes a respective base time-series signal. Ratio signals that are representative of time-series signals are computed, wherein the ratio signals are based upon the base time-series signal and other respective time-series signals in a group of time-series signals.

A location-related entity ranking technique is described that allows a user see the ranking of location-related entities near a desired location in response to a query. The technique can leverage the searches performed by a community of mobile device users at a given location and at a given time to infer the location-related entities that are popular at this specific location and time window. The technique can also filter out or re-rank these location-related entities based on the personal preferences of the person that submits the query and group preferences of a group to which the user belongs. The personal preferences can also be context specific (i.e. different restaurant preferences for lunch and dinner times).
摘要:
Architecture that facilitates the estimation of interference among workloads (e.g., virtual machines) due to sharing of a shared resource (e.g., a shared cache of a computer processor), and optimization of a desired performance objective such as power or energy use in the presence of the interference. Estimation is to the extent of interference by characterizing the nature of shared resource usage and its effect on performance. Performance optimization is accomplished using metrics based on the above estimation, or alternatively, an explicit measurement of the interference effects. Methods are employed to estimate interference on the workload's performance with changes in availability of the shared resource or with combinations of other workloads sharing the same resource and allocating workloads to one or more physical computers or resources to workloads such that a desired performance objective is optimized. The methods can include allocating workloads on demand.

摘要:
In a data center which includes a plurality of servers, a discovery computer, a power measurement system (PMS), and a plurality of power-circuits which supply power to the servers, the discovery computer performs the following actions for each server. It transmits a first command to the server causing the server to start generating a power consumption signature if the server is able to do so. Upon receiving a SUCCESS response from the server, it instructs the PMS to start measuring the power consumption from each power-circuit. After a prescribed interval of time has elapsed, it collects the measurements from the PMS and analyzes the measurements to look for the presence of the signature. Upon detecting the signature in the measurement taken from a particular power-circuit, the discovery computer concludes that the server is connected to the particular power-circuit and creates a mapping there-between.
