  • Patent number: 10932265
    Abstract: Methods and apparatus for communicating and utilizing persistent allocation of resources are described herein. A base station may allocate persistent resources to a client station, and may associate the client station or persistent resource allocation with a particular shared NACK channel. The base station may monitor the NACK channel for a NACK indicating a map error. The base station may monitor the resource allocation to implicitly determine a map error. The base station may resend one or more persistent resource allocation information elements in response to the NACK or implicit error determination. A client station having a persistent resource allocation may monitor persistent resource allocation information elements in map messages and/or may indicate failure to receive a persistent resource allocation information element in a NACK message on a shared NACK channel.

  • Patent number: 10915417
    Abstract: First audit information corresponding to a first set of log entries associated with a transformation performed on first data is obtained, where the first audit information includes a first commutative result produced by applying a commutative function to object identifiers associated with the first set of log entries. Second audit information corresponding to a second set of log entries associated with the transformation performed on second data is obtained, with the second data being a different representation of the first data and where the second audit information includes a second commutative result produced by applying the commutative function to object identifiers associated with the second set of log entries. The first commutative result is compared with the second commutative result to validate whether the second data matches the first data. One or more actions are performed depending on whether the second data is the successful transformation of the first data.

  • Patent number: 10896082
    Abstract: Statistical application-agnostic fault detection of multi-process applications in environments with data trend includes at least one of: a multi-process application that runs on a host. Statistical events are collected and sent to a statistical fault detector. The statistical fault detector creates one or more distributions and compares recent statistical event data to historical statistical event data and uses deviation from historical norm for fault detection. If needed, trend is removed from event data prior to the creation of distributions. Faults are detected within the application and within the environment wherein the application executes, if conditions within the environment cause impaired application performance.

  • Patent number: 10891193
    Abstract: An application health monitoring system automatically resolves anomalies arising among clients of a messaging server. The messaging server clients (MSCs) include one or more applications and services included in the applications. The anomalies include MSC anomalies and process starter anomalies. When a messaging session is disconnected due to server restarts, the service may be automatically restarted a predetermined number of times to re-establish the connection. Similarly, if a process starter of a service fails to start up properly, the service can be automatically restarted a predetermined number of times before the anomaly is flagged for human review. The monitoring system also automatically implements rules whenever service configurations are changed in addition to validating web service ports and cloud provider queues.

  • Patent number: 10891209
    Abstract: A system, method, and computer readable medium for statistical application-agnostic fault detection of multi-process applications. The computer readable medium includes computer-executable instructions for execution by a processing system. A multi-process application runs on a host. Interceptors collect statistical events and sends said events to a statistical fault detector. The statistical fault detector creates one or more distributions and compares recent statistical event data to historical statistical event data and uses deviation from historical norm for fault detection. The present invention detects faults both within the application and within the environment wherein the application executes, if conditions within the environment cause impaired application performance. The invention also teaches consensus fault detection and elimination of cascading fault notifications based on a hierarchy of events and event groups.

  • Patent number: 10887391
    Abstract: Methods, systems, and products mirror data between local memory and remote storage. A write command is sent from a server to a remote storage device, and a timer is established. A current time of the timer is compared to a maximum time period. If the maximum time period expires without receipt of an acknowledgment to the write command, then a write error is assumed to exist to the remote storage device.

  • Patent number: 10860400
    Abstract: A method is used in monitoring an application in a computing environment. The method represents execution of the application on a system as a finite state machine. The finite state machine depicts at least one state of the application, where the state indicates at least one of successful application execution and unsuccessful application execution. The method identifies an error state within the finite state machine, where the error state indicates the unsuccessful application execution. The method identifies, by analyzing the finite state machine, a non-error state as a cause of the unsuccessful application execution, where the unsuccessful application execution is represented as a path comprising a plurality of states, where the path comprises the non-error state. The method maps the non-error state to a location in the application to identify the cause of the unsuccessful application execution.

  • Patent number: 10831578
    Abstract: A processing system, such as for an automobile, includes multiple processor cores, including an application core and a safety core, and a fault detection circuit in communication with the processor cores. The fault detection circuit includes a progress register for storing progress data of an application executed on the application core. The safety core, which executes a fault detection program, reads the progress data from the progress register, and generates an output based on the progress data and an expected behavior of the application. The safety core writes the output to a status register of the fault detection circuit. The fault detection circuit includes a controller that reads the status register and generates a fault signal when the output indicates there is a fault in the execution of the application. In response, the application core either recovers from the fault or runs in a safe mode.

  • Patent number: 10831627
    Abstract: An accelerator manager monitors and logs performance of multiple accelerators, analyzes the logged performance, determines from the logged performance of a selected accelerator a desired programmable device for the selected accelerator, and specifies the desired programmable device to one or more accelerator developers. The accelerator manager can further analyze the logged performance of the accelerators, and generate from the analyzed logged performance an ordered list of test cases, ordered from fastest to slowest. A test case is selected, and when the estimated simulation time for the selected test case is less than the estimated synthesis time for the test case, the test case is simulated and run. When the estimated simulation time for the selected test case is greater than the estimated synthesis time for the text case, the selected test case is synthesized and run.
