  • Patent number: 10776036
    Abstract: An agent for managing virtual machines includes a persistent storage and a processor. The persistent storage stores backup/restoration policies. The processor identifies a virtual machine of the virtual machines that is likely to fail and, in response to identifying the virtual machine, identifies backup data associated with the identified virtual machine; instantiates a clone of the identified virtual machine using the identified backup; exposes the clone while the identified virtual machine is exposed; and hides the virtual machine after the clone is exposed.

  • Patent number: 10776142
    Abstract: Disclosed herein are techniques for configuring a shell logic in a configurable computing system while a client virtual machine (VM) using the shell logic is active. In certain embodiments, a configurable device includes a client configurable circuit associated with a client virtual machine, and a shell logic configured to isolate the client configurable circuit. The shell logic includes a reconfigurable shell, an isolation logic, and a packet processing logic. The isolation logic is configured to disable communication between the reconfigurable shell and the client virtual machine when the reconfigurable shell is being reconfigured. The packet processing logic is configured to service transactions between the client virtual machine and the configurable device after the communication between the reconfigurable shell and the client virtual machine is disabled.

  • Publication number: 20200257454
    Abstract: Methods and apparatus are disclosed for securely erasing partitions of reconfigurable logic devices such as FPGAs in a multi-tenant server environment. In one example, a method of securely erasing an FPGA includes identifying one partition of previously-programmed resources in the FPGA, erasing the identified partition by storing new values in memory or storage elements of the identified partition, and storing new values in memory or storage elements of additional external resources electrically connected to the integrated circuit and associated with the identified partition. Thus, other partitions and subsequent users of the identified partition are prevented from accessing the securely erased data. A configuration circuit, accessible by a host computer via DMA, can be programmed into the FPGA reconfigurable logic for performing the disclosed erasing operations.

  • Patent number: 10694189
    Abstract: Reference data is one type of data that the video accelerator may frequently be read from external memory. In various examples, the video accelerator can adaptively select inter-prediction modes based on the bandwidth to external memory that is available at any point in time. The video accelerator can determine the amount of bandwidth that is available, and when the bandwidth is insufficient for obtaining reference data for all possible inter-prediction modes, the video accelerator can select an inter-prediction mode based on the size of the reference window associated with the inter-prediction mode, the size being within an amount of data that can be read with the available bandwidth. The video accelerator can then obtain a reference window from external memory, and perform prediction using the selected inter-prediction mode and the reference window.

  • Patent number: 10599361
    Abstract: A backup agent for orchestrating backups of production hosts includes a persistent storage that stores backup policies and a backup manager that obtains a backup analysis request for a virtual machine hosted by the production hosts; generate a dependency graph based on: backups associated with the virtual machines, and the backup policies associated with the backups; and displays a graphical user interface, using the dependency graph, including user interactive markers based on the backups and dependency indicators interconnecting the user interactive markers. While the graphical user interface is displayed, the backup manager obtains a potential backup policy update based on a user interaction with one of the user interactive markers. After obtaining the potential backup policy update, the backup manager updates the graphical user interface to reflect the potential backup policy update. After updating the graphical user interface, the backup manager initiates generation of the backup.

  • Patent number: 10592322
    Abstract: Disclosed herein are techniques for preventing or minimizing completion timeout errors on a computer device. An apparatus includes a processing logic circuit configured to perform transactions requested by a requester device, and a timeout prevention logic coupled to the processing logic circuit. The timeout prevention logic includes a timeout logic and a moderation logic. The timeout logic is configured to, when the processing logic circuit fails to complete a particular transaction requested by the requester device within a reconfigurable time period, generate a timeout event and complete the particular requested transaction. The moderation logic is configured to determine a number of timeout events generated by the timeout logic during a monitoring time period, and set the reconfigurable time period based on the number of timeout events generated by the timeout logic during the monitoring time period.
