| 20080229127 | Method and System for Estimating Processor Utilization from Power Measurements - 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. | 09-18-2008 |
| 20080244281 | Method and System for Associating Power Consumption with a Network Address - A system for associating power consumption with a network address. Network traffic is inspected to determine network addresses. The network addresses are assigned to one or more servers. A power output of a plurality of power outlets is measured to determine a power consumption of the one or more servers connected to the plurality of power outlets. The network addresses assigned to the one or more servers is associated with the power consumption of the one or more servers. A total power consumption is calculated for the one or more servers having an association of network addresses with power consumption. Then, the total power consumption is recorded for the one or more servers in a table and a user is provided access to the table. | 10-02-2008 |

| 20090144566 | Method for Equalizing Performance of Computing Components - A performance measure (e.g., processor speed) for computing components such as servers is optimized by creating models of power consumption versus the performance measure for each server, adding the power models to derive an overall power model, and calculating an optimum set point for the performance measure which corresponds to a power limit on the servers using the overall power model. The set point is then used to set power budgets for the servers based on their power models, and the servers maintain power levels no greater than their respective power budgets. The server power models are preferably created in real time by monitoring power consumption and the performance measure to derive sets of data points for the servers, and performing regression on the sets of data points to yield power models for the servers. Multiple server power models may be created for different program applications. | 06-04-2009 |
