Abstract: Aspects of the disclosure allocate shares of processing resources or other physical resources among virtual machines (VMs) operating as, for example, virtual desktops on a plurality of host computing devices. Allocations of resources are adjusted based on the user activity, VM activity, and/or application activity detected by an agent executing on each VM. Allocated shares may be boosted, unboosted, or normalized, depending on the type and duration of detected activity, by a resource allocation manager executing on a management server.

Abstract: Examples described herein enable memory state sharing among a plurality of virtual machines (VM) including a parent VM and a child VM. A request for memory state sharing between the parent VM and the child VM is received, and the parent VM is suspended. The child VM resumes execution of one or more suspended applications. In one example, the child FM is forked with pre-loaded, suspended applications from the parent VM. Aspects of the disclosure offer a high performance, resource efficient solution that outperforms traditional approaches in areas of software compatibility, stability, quality of service control, re-source utilization, and more.

Abstract: The disclosure herein describes a client-side system that enhances user experience on a remoting client without consuming additional network bandwidth. During operation, the system receives a sequence of frame updates for a display screen, and determines a sequence of frames corresponding to the frame updates. The system further adaptively applies one or more image enhancing techniques to the sequence of frames based on available network bandwidth, frame refresh rate, or image quality. The image enhancement techniques include predicting a frame based on previously received frames, interpolating a frame based on at least two buffered frames, and reducing appearance of artifacts in a received frame, thereby reducing visual artifacts.

Abstract: In one embodiment, a method displays images from a remote desktop of a desktop GUI on a client device. The method receives a plurality of image blocks for a frame update of an image of the desktop GUI being displayed on the client device. The remote desktop is being run on a host. The client device determines that one or more missing image blocks have not been received for the frame update and determines if the frame update should be performed without the one or more missing image blocks. If the frame update of the desktop GUI should be performed without the one or more missing image blocks, the client device performs the frame update of the desktop GUI using the plurality of image blocks without using the one or more missing image blocks.

Abstract: Methods, systems, and computer programs are provided for measuring the performance of a remote display. One method includes an operation for embedding in display frames a respective frame identifier and a respective frame picture. The respective frame picture is placed in a respective region that depends of the value of the respective frame identifier. Additionally, the method includes operations for sending the plurality of display frames to a remote client, and for extracting each received frame picture from the respective region of each received display frame at the remote client based on the received frame identifier. The received frame quality is calculated for each received display frame based on the comparison of the extracted received frame picture with the respective frame picture. Further, the method includes an operation for calculating a remote display quality for the remote client based on the calculated received frame quality for the received display frames.
