Power system components are mapped using a controller and a data collection system. The controller is operable to transmit a first power system component ID for the first power system component to a second power system component, wherein the second power system component receives power from the first power system component. The data collection system is operable to receive from the second power system component the first power system component ID and a second power system component ID for the second power system component. The data collection system is further operable to associate the first power system component with the second power system component based on the received IDs.

A plurality of computer systems is operable to execute an application. A power consumption is determined for a first computer system if the first computer system were to execute the application, and a power consumption is determined for at least one other computer system if the second computer system were to execute the application. One of the computer systems is selected to execute the application based on the determined power consumptions.

A computer system uses a prefetch prediction model having energy usage parameters to predict the impact of prefetching specified files on the system's energy usage. A prefetch prediction engine utilizes the prefetch prediction model to evaluate the specified files with respect to prefetch criteria, including energy efficiency prefetch criteria, and generates a prefetch decision with respect to each file of the specified files. For each specified file for which the prefetch prediction engine generates an affirmative prefetch decision, an identifying entry is stored in a queue. The computer system fetches files identified by entries in the queue, although some or all of the entries in the queue at any one time may be deleted if it is determined that the identified files are no longer likely to be needed by the computer system.

Load demands in a power system are managed by determining whether load demands on one or more power system components need to be varied. If the load demands need to be varied, new load demands to be placed on the power system components are determined. The load demands on the power system components are controlled such that the load demands are substantially equal to the new load demands.

A system for managing inventory of components in a room. The system includes an identification device configured to communicate identification information relating to an associated component, a reader device configured to substantially autonomously receive the identification information from the identification device, and means for identifying the locations of the identification devices. The system also includes a controller configured to communicate with the reader device and compile the identification information received from the reader device and the locations of the identification devices to maintain an inventory of the components.
摘要:
A cooling system for cooling computer systems detects heat dissipated by the computer systems. If the heat dissipated by the computer systems exceeds a threshold, at least one component of the computer systems is placed in a lower-power state to reduce heat dissipation.

A primary power supply and a secondary power supply are operable to supply power to at least one electrical device. A power demand of the electrical device is determined, and an efficient operating point for the primary power supply is determined. One or more of the primary power supply and the secondary power supply are used to supply power to the electrical device based on whether the primary power supply operating at an efficient operating point is operable to meet the power demand of the at least one electrical device.

In a graphics pipeline, a rasterizer circuit generates fragments for an image having multiple surfaces that have been tessellated into primitive objects, such as triangles. First and second fragments are associated with the same pixel. A merge buffer merges the first fragment with the second fragment when the two fragments belong to the same tessellated surface, the first fragment's primitive is adjacent to the second fragment's primitive, both fragments face either toward or away from the viewer, and the first and second fragment are sufficiently similar that merging is unlikely to introduce visually objectionable artifacts. A frame buffer receives fragments from the merge buffer, stores the fragments, combines the fragments into pixels, and outputs the pixels to a display.
摘要:
At least one computer system receives power from a power system having a maximum power output based on a nominal power consumption of the at least one computer system. The power system is operable to detect an amount of power consumed by the at least one computer system, and compare the power consumption to a threshold based on the maximum power output of the power supply. The power system is operable to place one or more components of the at least one computer system in a lower-power state to reduce power consumption in response to the amount of power consumed by the at least one computer system exceeding the threshold.
摘要:
A primary power system and a secondary power system are operable to supply power to at least one cooling system component in a cooling system. The amount of power supplied by the primary power system and the secondary power system to the at least one cooling system component is controlled based on an operating level threshold for the at least one cooling system component.
