    Abstract: Methods and apparatus for receiving uploaded data from a sender at a receiver. A data deduplication technique is described that may reduce the bandwidth used in uploading data from the sender to the receiver. In the technique, the receiver, rather than the sender, maintains a fingerprint dictionary for previously uploaded data. When a sender has additional data to be uploaded, the sender extracts fingerprints for units of the data and sends the fingerprints to the receiver. The receiver checks its fingerprint dictionary to determine the data units to be uploaded and notifies the sender of the identified units, which then sends the identified units of data to the receiver. The technique may, for example, be applied in virtualized data store systems to reduce bandwidth usage in uploading data.

  • Patent number: 10176550
    Abstract: An architecture for implementing a mechanism for displaying GPU resource usage and dynamically allocating GPU resources in a networked virtualization system is provided. The mechanism compares an initial allocation of GPU resources to virtual machines supported by one or more nodes of the networked virtualization system to a current GPU resource usage by the virtual machines. Based at least in part on the comparison and workloads processed by the virtual machines, the mechanism may reallocate GPU resources to one or more of the virtual machines. A virtual machine is reassigned to a different vGPU profile if reassignment is likely to achieve a more efficient allocation of GPU resources to the virtual machine. A user interface indicating GPU resource usage relative to GPU resource allocation may also be generated and displayed.

  • Patent number: 10176008
    Abstract: Systems herein allow a user to load a virtual work environment on a terminal, such as a workstation, based on authentication mechanisms built into a user device, such as a cell phone. The user device can authenticate with a management server using an SAML token. The management server can track which virtual machines and configurations make up the user's work environment, and can send that information to the user device for loading the virtual machines. When the user wishes to load the virtual machines at a terminal, the user device can send the SAML token to the terminal for use in authenticating with the management server. The management server can then provide the configurations for the virtual machines that the user selects to load at the terminal.

  • Patent number: 10169088
    Abstract: An example method for managing memory includes receiving an inflate notification including a first identifier corresponding to a first time. The inflate notification indicates that a set of guest memory pages is unused by the guest at the first time. The method also includes determining whether the first identifier precedes a last identifier corresponding to a second time and included in a previously sent inflate request to the guest. If the first identifier does not precede the last identifier, the method also includes (i) for a first subset of the set modified since the first time, determining to not reclaim a first set of host memory pages corresponding to the first subset of guest memory pages, and (ii) for a second subset not modified since the first time, reclaiming a second set of host memory pages corresponding to the second subset of guest memory pages.

  • Patent number: 10169065
    Abstract: Live migration of a hardware accelerated application may be orchestrated by cloud services to transfer the application from a source server to a destination server. The live migration may be triggered by probe circuitry that monitors quality of service metrics for migration conditions at the source server. When live migration is initiated by the cloud services, a snapshot of all state information relevant to the application at the source server may be saved to network attached storage accessible by the destination server. Changes to said state information at the source server may be mirrored onto the network attached storage. The destination server may copy the snapshot and subsequent changes and run the application in parallel before taking complete control of the application. After a handshake operation between the source and destination servers, the application may be shut down at the source server.

  • Patent number: 10171291
    Abstract: A method, system, and/or computer program product establishes and utilizes a tenant-specific log for events related to a cloud-based service. A metamodel is created for a cloud-based service provided to a specific tenant of a cloud. The metamodel describes types of resources that are providing the cloud-based service that the specific tenant desires to monitor. In response to the cloud-based service being executed, the metamodel is used to identify a set of resources that are actually providing the cloud-based service for the specific tenant. A tenant-specific log is established to tracks events that occur on each actual resource from the set of resources, and records access to the specific unit of hardware by an authorized user of the specific unit of hardware. Operations related to the cloud-based service are transferred from the specific unit of hardware to a local device that is available only to the specific tenant.

  • Patent number: 10162688
    Abstract: A service manages a plurality of virtual machine instances for low latency execution of user codes. The service can provide the capability to execute user code in response to events triggered on an auxillary service to provide implicit and automatic rate matching and scaling between events being triggered on the auxiliary service and the corresponding execution of user code on various virtual machine instances. An auxiliary service may be configured as an event triggering service to detect events and generate event messages for execution of the user codes. The service can request, receive, or poll for event messages directly from the auxiliary service or via an intermediary message service. Event messages can be rapidly converted to requests to execute user code on the service. The time from processing the event message to initiating a request to begin code execution is less than a predetermined duration, for example, 100 ms.
