US10922125B2 Capability liveness of containerized services
An apparatus may include a processor that may access and analyze a live log stream of activity of the containerized service and determine whether the containerized service is able to provide a capability of the service based on the analysis. For example, the processor may determine whether the containerized service is executing but is in a hung state and cannot provide the capability. To do so, the processor may parse the live log stream for comparison with log patterns that indicate that the service is no longer able to provide the capability. The patterns may be generated based on observations of output by services that are hung or otherwise cannot provide their respective capabilities. The processor may cause the container to be restarted when the analysis indicates that the capability is not being provided by the containerized service, such as when the containerized service is in a hung state.

US10922091B2 Distributed realtime edge-core analytics with feedback
Example implementations described herein are directed to the management of data received from an edge side when an update is issued to edge nodes from a core apparatus.

Example implementations described herein address the processing of data from edge nodes when such an intermediate state occurs by conducting reprocessing of data when data is transmitted from edge nodes operating from an old configuration.
US10922084B2 Handling of inter-element address hazards for vector instructions
An apparatus has processing circuitry supporting vector load and store instructions. In response to a transaction start event, the processing circuitry executes one or more subsequent instructions speculatively. In response to a transaction end event, the processing circuitry commits speculative results of those instructions. Hazard detection circuitry detects whether an inter-element address hazard occurs between an address for data element J for an earlier vector load instruction and an address for data element K for a later vector store instruction, where K and J are not equal. In response to detecting the inter-element address hazard, the hazard detection circuitry triggers the processing circuitry to abort further processing of the instructions following the transaction start event and to prevent the speculative results being committed. This approach can provide faster performance for vectorised code.
