Abstract: The disclosure relates to a method of switching data sources during a rolling upgrade of a leader-based distributed service. In at least one implementation, the method includes establishing, at a computing device in a cluster of devices in a network, a watch for notification of completion of a rolling upgrade on all devices in the cluster; restarting the computing device on completion of the rolling upgrade; switching, at the computing device, from a first data source to a second data source once the rolling upgrade is complete on all devices in the cluster; if the computing device is a leader device in the cluster, migrating tasks from the first data source to the second data source after completion of the rolling upgrade; and if the computing device is a non-leader device in the cluster, determining if task migration to the second data source is done and, when done, sending a store object to the second data source.

Abstract: In one approach, an import mechanism allows new hardware intrinsics to be utilized by writing or updating a library of source code, rather than specifically modifying the virtual machine for each new intrinsic. Thus, once the architecture is in place to allow the import mechanism to function, the virtual machine itself (e.g. the code which implements the virtual machine) no longer needs to be modified in order to allow new intrinsics to be utilized by end user programmers. Since source code is typically more convenient to write than the language used to implement the virtual machine and the risk of miscoding the virtual machine is minimized when introducing new intrinsics, the import mechanism described herein increases the efficiency at which new hardware intrinsics can be introduced.

Abstract: The disclosed technology adjusts hardware settings to map preferences consistently of a user experience across multiple hardware devices, despite there being different hardware capabilities and performance parameters among the different devices. A hardware settings translation engine receives a reference hardware setting of a reference computing device, a set of reference hardware performance parameter values, and a set of target hardware performance parameter values. The hardware settings translation engine then maps the set of target hardware performance parameter values to the set of reference hardware performance parameter values to yield a hardware adjustment map. The hardware settings translation engine determines the target hardware setting based on the reference hardware adjustment map and the reference hardware setting. The hardware settings translation engine sets the target hardware to the target hardware setting.

Abstract: In a computer system running at least a first virtual machine (VM) and a second VM on virtualization software, a computer implemented method for the second VM to provide quasi-lockstep fault tolerance for the first VM includes executing a workload on the first VM and the second VM that involves producing at least one externally visible output and comparing an externally visible output of the second VM with an externally visible output of the first VM to determine if there is an output match. In response to a determination that the externally visible output of the second VM does not match the externally visible output of the first VM, a resynchronization of the second VM is executed. The externally visible output of the first VM is kept from being output externally until completion of the resynchronization.

For the job, it is iteratively determined a backlog growth over a first period of time; a backlog volume; and whether to adjust a quantity of processing resources. For each iteration for which the quantity of processing resources allocated to the job are determined to be adjusted, adjusting the quantity of processing resources allocated to the job. For each iteration for which the quantity of processing resources allocated to the job are determined not to be adjusted, maintaining the quantity of processing resources allocated to the job.

Abstract: Techniques disclosed herein provide an approach for assigning resource consumers to available resources. In one embodiment, components of a distributed scheduler are organized into a hierarchy, such as a tree. A placement request received at a root scheduler of the hierarchy is propagated down the hierarchy, either to all children or to randomly selected subsets of children of each scheduler in the hierarchy. Leaf schedulers in the hierarchy that receive the request each propagate back up a score indicating the amount of free resources in its corresponding resource bucket. Branch schedulers then compare scores that they receive, and each further propagate one of the received scores, such as the highest score, based on the comparison, until the root scheduler is reached. The root scheduler makes an additional comparison and returns one of the resource buckets in response to the received placement request.

Abstract: In general, techniques are described for providing software redundancy for Virtual Network Functions (VNF). In one example, a method includes, by a host process executed by an insertable service card of a network device, pinning, to a plurality of hardware-based processors, active threads of an active network function. The host process pins, to a single hardware-based processor, backup threads of a backup network function for the active network function, wherein the plurality of hardware-based processors does not include the single hardware-based processor. The host process pins, to the single hardware-based processor, management threads of the active and backup network functions. The single hardware-based processor executes the management threads of the active and backup network functions to cause the management thread of the backup network function to receive, from the management thread of the active network function, state data generated by the active threads.

Abstract: Concurrent threads may be synchronized at the level of the memory words they access rather than at the level of the lock that protects the execution of critical sections. Each lock may be associated with an array of flags and each flag may indicate ownership of certain memory words. A pessimistic thread may set flags corresponding to memory words it is accessing in the critical section, while an optimistic thread may read the corresponding flag before any memory access to ensure that the flag is not set and that therefore the associated memory word is not being accessed by the other thread. Thus, optimistic threads that do not have conflicts with the pessimistic thread may not have to wait for the pessimistic thread to release the lock before proceeding.

The option in the auto-discovery packet includes the message received from the second application.

Abstract: Systems for computing cluster management. One embodiment commences upon receiving a set of observed workload parameters corresponding to one or more observable workloads that run in a computing cluster. While the workloads are running, workload stimulus and cluster response observations are taken and used to generate a workload resource usage predictive model based on mappings or correlations between the observable workloads parameters and observed resource usage measurements. A set of planned workloads are applied to the workload resource usage predictive model to predict a set of corresponding predicted resource usage demands. The predicted resource usage demands are then mapped to a set of recommended hardware to form resource deployment recommendations that satisfy at least some of the corresponding resource usage demands while also observing a set of hardware model compatibility constraints.

Abstract: A request is received from a client for determining task completion of a first set of tasks associated with attributes, the first set of tasks scheduled to be performed within a first time period. For each of the attributes, a completion rate of one or more of a second set of tasks is calculated that are associated with the attribute. The second set of tasks has been performed during a second time period in the past. An isotonic regression operation and/or temporal smoothing are performed on the completion rates associated with the attributes of the second set of tasks that have been performed during the second time period to calibrate the completion rates. Possible completion for the attributes of the first set of tasks to be performed in the first time period is calculated based on the calibrated completion rates of the second set of tasks.
