Abstract: A method and associated systems for automated orchestration of complex server provisioning tasks, An orchestration-optimization system receives input that identifies a destination, platform, and pattern of tasks that together characterize a procedure for building a particular virtualized computer environment. The system selects a set of generic orchestration methods that identify in general terms each task required to build the environment. The system then embeds into the orchestration methods all currently known contextual data associated with the specified build procedure, converting the generic methods into a build-specific runlist of tasks. When the environment is ready to be built, additional environment-specific data that becomes known only at build time is inserted into placeholders previously embedded into the runlist tasks. The system then performs the sequence of runlist tasks in order to automatically build the virtualized system.

Abstract: One embodiment of the present disclosure sets forth an effective way to maintain fairness and order in the scheduling of common resource access requests related to replay operations. Specifically, a streaming multiprocessor (SM) includes a total order queue (TOQ) configured to schedule the access requests over one or more execution cycles. Access requests are allowed to make forward progress when needed common resources have been allocated to the request. Where multiple access requests require the same common resource, priority is given to the older access request. Access requests may be placed in a sleep state pending availability of certain common resources. Deadlock may be avoided by allowing an older access request to steal resources from a younger resource request. One advantage of the disclosed technique is that older common resource access requests are not repeatedly blocked from making forward progress by newer access requests.

Abstract: A new approach is proposed that contemplates systems and methods to support a mechanism to offload all aspects of inline SSL processing of an application running on a server/host to an embedded networking device such as a Network Interface Card (NIC), which serves as a hardware accelerator for all applications running on the server that need to have a secure connection with a remote client device over a network. By utilizing a plurality of its software and hardware features, the embedded networking device is configured to process all SSL operations of the secure connection inline, i.e., the SSL operations are performed as packets are transferred between the host and the client over the network, rather than having the SSL operations offloaded to the NIC, which then returns the packets to the host (or the remote client device) before they can be transmitted to the remote client device (or to the host).

Abstract: An operator control element in a motor vehicle generates an activation signal as a function of the activation of the operating element, and a control unit receives the activation signal and measures a signal length of the activation signal, and signals the activation if the signal length becomes greater than a predetermined debounce time.

The control unit determines for this purpose an operating parameter, and on the basis of the operating parameter it is detected that a supply voltage, made available at the control unit, satisfies a predetermined instability criterion, and when the instability criterion is satisfied the control unit delays the measurement of the signal length for a predetermined blocking time.

Abstract: A user equipment node, upon determining that the data loss in a requested file is above, or likely to be above a threshold value, transmits a delivery missing report to a server node indicating that the data loss in the requested file is above the threshold value.

This enables a point-to-multipoint file repair procedure to be enabled sooner, and prevent a flood of point-to-point file repairs.

Data that is necessary after the power supply is restarted can be backed up from the volatile register to the nonvolatile register before the power supply is stopped. Data that is unnecessary is not backed up from the volatile register to the nonvolatile register before the power supply is stopped.
