Systems and methods for controlling power consumption in a computer system. For each of a plurality of interactive applications, the method changes a frequency at which a processor of the computer system runs, receives an indication of user satisfaction, determines a relationship between the changed frequency and the user satisfaction of the interactive application, and stores the determined relationship information. The determined relationship can distinguish between different users and different interactive applications. A frequency may be selected from the discrete frequencies at which the processor of the computer system runs based on the determined relationship information for a particular user and a particular interactive application running on the processor of the computer system. The processor may be adapted to run at the selected frequency.

System and method for controlling power consumption in a computer system based on user satisfaction

A system and method for leveraging physiological traits to control microprocessor frequency are disclosed. In some embodiments, the system and method may optimize, for example, a particular processor-based architecture based on, for example, end user satisfaction. In some embodiments, the system and method may determine, for example, whether their users are satisfied to provide higher efficiency, improved reliability, reduced power consumption, increased security, and a better user experience. The system and method may use, for example, biometric input devices to provide information about a user's physiological traits to a computer system. Biometric input devices may include, for example, one or more of the following: an eye tracker, a galvanic skin response sensor, and/or a force sensor.

System and method for leveraging human physiological traits to control microprocessor frequency

Certain embodiments of the present invention provide systems and method for automatic inference and adaptation of a virtualized computer environment. Certain embodiments of a system include a virtual topology and traffic inference framework tool adapted to monitor traffic for an application on a virtual network to produce a view of network demands for the application. The system also includes a monitoring tool adapted to monitor performance of an underlying physical network associated with the virtual network using traffic for the application. Further, the system includes an adaptation component adapted to automatically adapt the application to the virtual network based on the measured application traffic, the monitored network performance, and one or more adaptation control algorithms.

Certain embodiments of the present invention provide for a system and method for network computing. In an embodiment, the system may include a storage unit for archiving historical user events and historical server events. The system may also include a processing unit for receiving a current user event and generating one or more predicted server events. The processing unit may execute a screen update based on the one or more predicted server events. The system may also include a comparison unit having computer software for comparing one or more predicted server events with one or more server-supplied server events. The one or more server-supplied server events may be generated based on the current user event. In an embodiment, the system also includes an undo unit having computer software for executing an undo algorithm. The undo unit alters the non-matching events to match the server-supplied server events.

System and method for speculative remote display

Certain embodiments of the present invention provide a method for power management including determining at least one of an operating frequency and an operating voltage for a processor and configuring the processor based on the determined at least one of the operating frequency and the operating voltage. The operating frequency is determined based at least in part on direct user input. The operating voltage is determined based at least in part on an individual profile for processor.
