  • Method for establishing a drive image in a computing environment
    Publication number: 20020147862
    Abstract: A method for performing a write operation to a hard drive or other memory space is provided. The hard drive is represented as at least two files. The first file is a parent drive and includes some content of the hard drive. Writes made to the hard drive are recorded in a second file, known as a differencing drive. Because no changes are made to the content of the parent drive, the content of the hard drive may be rolled back to the content of the parent drive by discarding the differencing drive.

  • Monitoring And Benchmarking Client Performance From The Server-Side
    Publication number: 20130060837
    Abstract: Included herein are embodiments of monitoring and benchmarking client devices from a server. A server, data center, and/or cloud computing environment may monitor certain aspects of a remote desktop session. The rendering, capture, and compression of a desktop may be monitored. The time between the sending of frames to a thin client can be monitored, the network bandwidth available can be monitored and the time between sending a frame a receiving a response from the thin client can be monitored. Based on these values, a benchmark for the remote desktop experience can be determined.

  • DELIVERING A SINGLE END USER EXPERIENCE TO A CLIENT FROM MULTIPLE SERVERS
    Publication number: 20190196858
    Abstract: Methods, systems, and computer readable media are disclosed for creating a multi-port client server connection in a remote desktop environment. In an embodiment, the multi-client server connection can decouple client-server connection and client-server input from graphics delivery from the server to the client. Such embodiment provides higher server performance and enables dynamic server resource management. The multi-client server connection can be implemented in a virtual environment or between physical machines where one set of physical machines receives the graphics requests from the client and another set of physical machines generates and transmits display data to the client.

  • Prevention of DOS Attack by a Rogue Graphics Application
    Publication number: 20120075314
    Abstract: A mechanism is described for mitigating the effects of such a DoS attack by detecting a multiple TDR situation within a short duration, identifying the errant virtual machines, and suspending all rendering ability for that virtual machine or set of virtual machines. While the disclosed embodiments are described in the context of virtual machines, the principles may be extended to the general problem of DoS attacks due to TDRs and bugchecks on any physical machine that includes a GPU. For example, DoS attacks can be generated from web sites directly using GPU rendering.

  • DYNAMIC PROVISIONING OF VIRTUAL VIDEO MEMORY BASED ON VIRTUAL VIDEO CONTROLLER CONFIGURATION
    Publication number: 20180210758
    Abstract: Memory is reserved in a virtualized computing environment for graphics processing of each child partition in the computing environment. A video memory controller can identify video settings for child partitions. The video memory controller can determine an amount of memory for graphics processing for a child partition based on the video settings for that child partition. The video memory can also request an amount of memory to be reserved for that child partition based on the calculated amount of memory. Reserving memory for graphics processing of child partitions in this way allows for a sufficient amount of memory to be reserved for a child partition without wasting memory resources by reserving significantly more memory than is needed for the child partition.
