Abstract: Hot restart of a hypervisor by replacing a running first hypervisor by a second hypervisor with minimally perceptible downtime to guest partitions. A first hypervisor is executed on a computing system. The first hypervisor is configured to create one or more guest partitions. During the hot restart, a service partition is generated and initialized with a second hypervisor. At least a portion of runtime state of the first hypervisor is migrated and synchronized to the second hypervisor using inverse hypercalls. After the synchronization, the second hypervisor is devirtualized from the service partition to replace the first hypervisor. Devirtualizing includes transferring control of hardware resources from the first hypervisor to the second hypervisor, using the previously migrated and synchronized runtime state.

Abstract: Scalable implementations of exact distinct counts and multiple exact distinct counts in distributed query processing systems are implemented via systems and devices. Distinct counts and multiple exact distinct counts for identifiers/values are performed based on keys. For distinct counts, datasets including data fields are sorted by values of fields and divided into balanced partitions in distributed servers. Subsets of fields with the same value are partitioned together. Key presence is determined for subsets on each partition, and the number of instances for the key are aggregated for exact distinct counts of values. For multiple distinct counts, fields of a dataset are combined by un-pivoting field columns. Compound keys are generated for combined fields from field identifiers of the combined fields and values of another field. Totals of unique values of the combined fields are determined for values in the counted field based on the compound keys.

The code insertion engine uses a neural expansion model and a neural selector model to predict the one or more statements most likely to be inserted into the insertion point that are syntactically and semantically consistent with the surrounding context of the existing program.

Abstract: Innovations in control and use of chroma quantization parameter (“QP”) values that depend on luma QP values. More generally, the innovations relate to control and use of QP values for a secondary color component that depend on QP values for a primary color component. For example, during encoding, an encoder determines a QP index from a primary component QP and secondary component QP offset. The encoder maps the QP index to a secondary component QP, which has an extended range. The encoder outputs at least part of a bitstream including the encoded content. A corresponding decoder receives at least part of a bitstream including encoded content. During decoding, the decoder determines a QP index from a primary component QP and secondary component QP offset, then maps the QP index to a secondary component QP, which has an extended range.

Abstract: Methods, systems, apparatuses, and computer-readable storage mediums described herein are configured to detect anomalous post-authentication behavior with respect to a user identity. For example, one or more audit logs that specify a plurality of actions performed with respect to the user identity of a platform-based identity service, while the user identity is authenticated with the platform-based identity service, are analyzed. The audit log(s) are analyzed via an anomaly prediction model that generates an anomaly score indicating a probability whether a particular sequence of actions of the plurality of actions is indicative of anomalous behavior. A determination is made that an anomalous behavior has occurred based on the anomaly score. In response to determining that anomalous behavior has occurred, a mitigation action may be performed that mitigates the anomalous behavior.

Abstract: The techniques described herein provide the ability for an owner of a content object to send an ephemeral link to participants in a meeting instance. An ephemeral link is a link to a content object that provides access to the content object for a time period associated with the meeting instance. In one example, the time period starts when the content object is shared during the meeting instance and ends when the meeting instance is scheduled to end. Thus, access to the content object via the link expires based on a scheduled end time of the meeting instance. However, in further examples described herein, the owner of the content object can dynamically adjust, via user input, the period of time during which the link provides access to the content object. The dynamic adjustment can extend the access or shorten the access to the content object via the link.

Abstract: There is provided a method of selectively patterning a device structure. A hollow shadow wall is formed on a substrate. The hollow shadow wall is formed of a base lying on a surface of the substrate, and one or more side walls connected to the base. The one or more side walls extend away from the surface of the substrate and around the base to define an internal cavity of the hollow shadow wall.

Abstract: Sampling operations enable a computer vision tool to regulate downstream tasks. The sampling operations can indicate which frames of a video sequence should be processed by different downstream tasks. For example, a computer vision tool receives encoded data for a given frame and uses the encoded data to determine inputs for machine learning models in different channels. The computer vision tool provides the inputs to the machine learning models, respectively, and fuses results from the machine learning models. In this way, the computer vision tool determines a set of event indicators for the given frame. Based at least in part on the event indicator(s) for the given frame, the computer vision tool regulates downstream tasks for the given frame (e.g., selectively performing or skipping downstream tasks for the given frame, or otherwise adjusting how and when downstream tasks are performed for the given frame).

Abstract: As part of managing delivery of a given packet flow according to a reliable transport protocol, a sender sends, to a receiver, a last flow packet among multiple flow packets of a flowlet. After sending the last flow packet but before satisfaction of a timeout condition for the last flow packet, the sender sends one or more end-of-flowlet (“EOF”) packets, which can be flush packets, query packets, or another type of packet. The sender receives, from the receiver, feedback metadata for the EOF packet(s) and updates a tracking window based at least in part on the feedback metadata. The sender selectively resends one or more unacknowledged flow packets according to the updated tracking window. In this way, the sender can quickly address any dropped packets or significantly delayed packets at the end of a flowlet, without waiting for the timeout condition to detect the dropped or delayed packets.

Abstract: Operators managing a cloud RAN collect vast amounts of data, e.g., node-level data, gNodeB level data, user level data, and flow-level data, which are utilized for network monitoring, evaluating key performance indicators (KPIs), and nodes management. Retrieving and visualizing information and values of different metrics is critical to managing network operation; however, data retrieval on large datasets is challenging. While foundation models perform poorly on large datasets, an accurate answer to a data query is generated by providing semantically similar metrics as context to a foundation model, thereby limiting the number of counters needed for processing the data query. The foundation model then generates a first output of metrics relevant to answering the data query and, based on the first output, generates a second output comprising query code (e.g., SQL or KQL) for computing the answer, thereby improving mathematical accuracy of the answer.

Abstract: As part of managing delivery of a packet flow according to a reliable transport protocol that supports multi-path delivery, a sender splits data into multiple flow packets of a flow and sends at least some of the flow packets to a receiver on multiple paths of a network. The sender receives feedback metadata and updates an out-of-order (“OOO”) tracking window. The sender also determines a metric that quantifies degree of OOO delivery. In general, the metric measures the extent to which flow packets have been successfully delivered OOO after a “missing” flow packet. If a sufficient count or range of flow packets have been acknowledged as received OOO after the missing flow packet, the missing flow packet is likely to have been dropped—not merely delayed. Depending on the metric, the sender selectively resends to the receiver one or more unacknowledged flow packets.

A multiplier performs a multiplication operation based at least in part on the latch output value.

Abstract: An object tracking tool integrates scene transition detection and/or dynamic queue resizing. By integrating shot transition detection, the object tracking tool can change which operations are performed depending on whether a shot transition has been detected. For example, if a shot transition is not detected, lower-complexity interpolation operations can be performed to determine spatial information for objects, instead of using higher-complexity object detection operations, which can reduce computational complexity. As another example, depending on whether a shot transition has been detected, the object tracking tool can adjust operations performed when associating identifiers with objects, which can improve accuracy of object tracking operations. With dynamic queue resizing, an object tracking tool can selectively adjust the maximum size of a queue used to store frames for object tracking.

Abstract: Data base performance is improved using write-behind optimization of covering cache. Non-volatile memory data cache includes a full copy of stored data file(s). Data cache and storage writes, checkpoints, and recovery may be decoupled (e.g., with separate writes, checkpoints and recoveries). A covering data cache supports improved performance by supporting database operation during storage delays or outages and/or by supporting reduced I/O operations using aggregate writes of contiguous data pages (e.g., clean and dirty pages) to stored data file(s). Aggregate writes reduce data file fragmentation and reduce the cost of snapshots. Performing write-behind operations in a background process with optimistic concurrency control may support improved database performance, for example, by not interfering with write operations to data cache. Data cache may store (e.g., in metadata) data cache checkpoint information and storage checkpoint information. A stored data file may store storage checkpoint information (e.g.
