Abstract: The disclosed embodiments provide a system that facilitates seamlessly switching between graphics-processing units (GPUs) to drive a display. In one embodiment, the system receives a request to switch from using a first GPU to using a second GPU to drive the display. In response to this request, the system uses a kernel thread which operates in the background to configure the second GPU to prepare the second GPU to drive the display. While the kernel thread is configuring the second GPU, the system continues to drive the display with the first GPU and a user thread continues to execute a window manager which performs operations associated with servicing user requests. When configuration of the second GPU is complete, the system switches the signal source for the display from the first GPU to the second GPU.

Abstract: What is disclosed is a novel system and method for parallel processing of intra-image data in a distributed computing environment. A generic architecture and method are presented which collectively facilitate image segmentation and block sorting and merging operations with a certain level of synchronization in a parallel image processing environment which has been traditionally difficult to parallelize. The present system and method enables pixel-level processing at higher speeds thus making it a viable service for a print/copy job document reproduction environment. The teachings hereof have been simulated on a cloud-based computing environment with a demonstrable increase of ?2× with nominal 8-way parallelism, and an increase of ?20×-100× on a graphics processor. In addition to production and office scenarios where intra-image processing are likely to be performed, these teachings are applicable to other domains where high-speed video and audio processing are desirable.

Abstract: The present invention provides a method and system for coordinating graphics processing units in a single computing system. A method is disclosed which allows for the construction of a list of shared display modes that may be employed by both of the graphics processing units to render an output in a display device. By creating the list of shared commonly supportable display modes, the output displayed in the display device may advantageously provide a consistent graphical experience persisting through the use of alternate graphics processing units in the system. One method builds a list of shared display modes by compiling a list from a GPU specific base mode list and dynamic display modes acquired from an attached display device. Another method provides the ability to generate graphical output configurations according to a user-selected display mode that persists when alternate graphics processing units in the system are used to generate graphical output.

Abstract: A graph exploration module is described which displays graph data (or any data set) using any one of an extensible collection of chart types. Some of the chart types may present aggregated results associated with the graph data. One chart type provides bars which represent aggregations of nodes in the graph data and a collection of links which represent relationships among the bars. The graph exploration module may present the chart in the context of an interactive exploration panel within an exploration canvas. A user can make various selections which prompt the graph exploration module to generate a new exploration panel, together with a link which connects to the new panel to the previous panel. This process can be repeated any number of times to produce one or more exploration paths which reveal a history of exploration actions made by the user(s). That history can be saved and later retrieved.

Abstract: Techniques are described to monitor a level of graphics processing activity and control power usage based on the level. When no graphics processing activity is detected for a period of time, then a timing controller for a display device is instructed to capture a current image and repeatedly display the captured image. The graphics processing devices can be powered down. When graphics processing activity is detected, the graphics processing devices are powered up and the components used to capture an image and display the captured image are powered down.
