Abstract: In various examples, there is provided methods performed by nodes in a cluster of nodes to establish a master clock at a new master node following a reconfiguration of the nodes included in the cluster, whereby the master clock is provided by an old master node prior to the reconfiguration, and synchronize a local clock of slave nodes to clock of the new master node. The new master node sends a message to the slave nodes instructing them to disable their respective local clocks, receives acknowledgements that the local clocks have been disabled, waits until a time at which all leases have expired for any nodes removed from the cluster, sets the value of its clock to be greater than a maximum value that could have been provided by the old master node at the time the leases expired and indicates to the other nodes to re-enable their local clocks.

Abstract: A system that implements a data storage service may store data on behalf of clients in multiple replicas on respective computing nodes. The system may employ an external service to select a master replica for a replica group. The master replica may service consistent read operations and/or write operations that are directed to the replica group (or to a data partition stored by the replica group). The master replica may employ a quorum based mechanism for performing replicated write operations, and a local lease mechanism for determining the replica authorized to perform consistent reads, even when the external service is unavailable. The master replica may propagate local leases to replica group members as replicated writes. If another replica assumes mastership for the replica group, it may not begin servicing consistent read operations that are directed to the replica group until the lease period for a current local lease expires.

In response to detected changes, the entity identifier translation server may identify one or more corresponding entity identifiers within the other data centers. For each of the corresponding entity identifiers within the other data centers, the entity identifier translation server may determine whether or not the corresponding entity identifier is to be synchronized with the newly-changed entity identifier in the first data center, and if so, may initiate synchronization processes.

Abstract: Embodiments of the present disclosure relate to presenting and synchronizing views of electronic document. In particular, a view management system can synchronize and present multiple synchronized views of an electronic document for display on a client device.

In response to detecting a user interaction with respect to a view, the view management system can cause a client device to apply the user interaction to each of multiple views (e.g., each view that is bound to the model). By synchronizing views, the view management system can enable a user to conveniently observe how one or more user interactions with respect to a view would appear across multiple views of an electronic document.

Abstract: Example implementations relate to determining whether network invariants are violated by flow rules to be implemented by the data plane of a network. In an example, a verification module implemented on a device receives a flow rule transmitted from an SDN controller to a switch, the flow rule relating to an event.

If determined that the flow rule matches one of the plurality of network invariants, the verification module determines whether the flow rule violates the matched network invariant. If determined that the flow rule does not match any of the plurality of network invariants, the verification module (1) reports the event associated with the flow rule to a policy management module, (2) receives a new network invariant related to the event from the policy management module, and (3) determines whether the flow rule violates the new network invariant.

Abstract: In one embodiment, a synchronization instruction causes a processor to ensure that specified threads included within a warp concurrently execute a single subsequent instruction. The specified threads include at least a first thread and a second thread. In operation, the first thread arrives at the synchronization instruction. The processor determines that the second thread has not yet arrived at the synchronization instruction and configures the first thread to stop executing instructions.

The processor then causes all the specified threads to execute the subsequent instruction. Advantageously, unlike conventional approaches to synchronizing threads, the synchronization instruction enables the processor to reliably and properly execute code that includes complex control flows and/or instructions that presuppose that threads are converged.

Abstract: An interface of a content management system manages storage and access of content on the system. For example, after receiving, from a client, a request to download a content item, the interface determines whether the request includes a valid token. If so, the interface sends a content item request to a storage service, retrieves the content item, and sends the content item to the client. Otherwise, the interface sends an authorization request to an authorization service, an authentication request to an authentication service, and a content item request to the storage service. Based on the requests, the interface determines whether the content item is available in storage and whether the client is authorized to access the content item. When the content item is available in storage and the client is authorized to access the content item, the interface retrieves the content item and sends the content item to the client.
