Examples allocate and schedule use of graphics processing unit (GPU) resources among a plurality of users executing virtual machines (VMs) or processes. During initialization, shares representing proportional access to the GPU resources are assigned and then adjusted based on graphics command characteristics. Quantum is allocated among the VMs based on the shares. At runtime, graphics commands from the VMs are queued and iteratively sent to the GPU based on a comparison between allocated quantum and a threshold quantum. In this manner, the GPU resources are fairly shared among the VMs.

Host-based GPU resource scheduling

One embodiment of the present invention provides a system that enables a user interface manager to modify a scene graph for an application. During operation, the system receives the scene graph for the application, wherein the scene graph defines visual attributes for a user interface associated with application. Next, the system uses the scene graph to render a visual output for the user interface, and displays the visual output to a user of the application. The system also enables the user interface manager to modify the scene graph, whereby the user interface manager can produce visual effects for the user interface in addition to visual effects produced by the application.
