Abstract: First firmware metadata and second firmware metadata are based on nonvolatile metadata stored in the nonvolatile memory device. A normal operation including a first management operation resulting in a change of the first firmware metadata and an access operation in which the nonvolatile memory device is accessed may be performed. A virtual operation is performed including a second management operation resulting in a change of the second firmware metadata and in which the access operation is not performed. Whether an error has occurred in the first firmware metadata is determined by comparing the change of the first firmware metadata resulting from the first management operation and the change of the second firmware metadata resulting from the second management operation. An error in the metadata may be monitored through the redundant performance of the management operation that results in the change of the metadata without a corresponding access to the nonvolatile memory device.

As a result, the testing computer can electronically communicate with the access device even when the testing computer is remotely located.

Abstract: Methods, systems, and apparatuses related to a memory fault map for an accelerated neural network. An artificial neural network can be accelerated by operating memory outside of the memory's baseline operating parameters. Doing so, however, often increases the amount of faulty data locations in the memory. Through creation and use of the disclosed fault map, however, artificial neural networks can be trained more quickly and using less bandwidth, which reduces the neural networks' sensitivity to these additional faulty data locations. Hardening a neural network to these memory faults allows the neural network to operate effectively even when using memory outside of that memory's baseline operating parameters.

The determined configurations in the plurality of different data management services are automatically implemented.

Abstract: A test stimulus generator generates error irritations, or error sequences, within a processor system. The test stimulus generator includes an initialization register, a pseudo-random number generator (PRNG), a clock subsystem, and an output register. The PRNG calculates an output value from an initialization value stored in the initialization register. The PRNG output value represents a unique error irritation and identifies one or more components within the processor system to handle the error irritation. The clock subsystem generates either a continuous or pulsed clock signal that transfers the initialization value into the PRNG. The output register stores the PRNG output value and transmits the corresponding error irritation to the processor components identified to handle the error irritation. The test stimulus generator generates error irritations in a predetermined or random order based on the initialization value. A corresponding method and computer program product are also disclosed.

Abstract: A hardware-assisted paravirtualized hardware watchdog is described that is used to detect and recover from computer malfunctions. A computing device determines that a hardware-implemented watchdog of the computing device does not comply with predetermined watchdog criteria, where the hardware-implemented watchdog is configured to send a reset signal when a first predetermined amount of time elapses without receipt of a first refresh signal. If the hardware-implemented watchdog does not comply with the predetermined watchdog criteria, a runtime watchdog service is initialized using a second predetermined amount of time. The runtime watchdog service is directed to periodically send the refresh signal to the hardware-implemented watchdog before an expiration of the first predetermined amount of time that causes the hardware-implemented watchdog to expire.

Abstract: A method of monitoring execution of computer instructions includes receiving data items representing real-time measurements of side-channel information emanating from execution of computer instructions, each data item forming a value of a corresponding dimension of a side-channel information vector, receiving, for two or more of the dimensions of the side-channel vector, classifiers that assign the corresponding values of a side-channel vector to classes, and classifying the data items in accordance with the received classifiers, wherein an orthogonal distance of the data item from the classifier indicates a confidence value of the classification, generating a combined a confidence value for the side-channel information vector a, and outputting a signal if a confidence value indicates affiliation to a selected one of the two classes with a predetermined probability. The method conducts a self-test by generating a combined confidence value based to ensure correct outputting of the confidence value.

Abstract: Apparatus and methods an artificial intelligence method of reducing failure in an informational flow of a data stream controlled by an Extract Transform Load process using a machine learning (“ML”) model training system are provided. The method may include deploying a software sensor that periodically captures data points for an extract job executed during an extract phase of the process. The method may also include building a behavior profile concurrently with the receipt of each of the data points. The method may further include comparing the behavior profile to behavior profiles stored in an Adverse Behavior Model database and behavior profiles stored in a Normal Behavior Model database. When the behavior profile is determined to have a threshold number of match points matching the behavior profile to behavior profiles in the Adverse Behavior Model database, the method may include increasing a target database storage capacity.

Abstract: One example method includes performing failure recovery operations in a computing system using matrix clocks. Each node or process in a computing system is associated with a matrix clock. As events and transitions occur in the computing systems, the matrix clocks are updated. The matrix clocks provide a chronological and casual view of the computing system and allow a recovery line to be determined in the event of system failure.

Abstract: Presented are concepts for processing an event log. Once such concept obtains an event log comprising a log of event occurrences for an executed process. It also obtains an events embedding model representative of relationships between a plurality of events of one or more processes. Based on the events embedding model, repeating events in the event log are clustered into one or more groups, and each of the one or more groups are associated with a respective identifier. Repeating events in the event log are then replaced with the identifier associated with the group that the repeating event is a member of.

Abstract: Described herein is a method, system, and non-transitory computer readable medium for helping customers in accessing data through an application from a replica database, detecting whether the replica database, zone of availability of the replica database, or geographical region encompassing the zone of availability is experiencing an outage or other failure, and re-routing traffic to a backup replica database accordingly. To assess the status of the database, metrics are pushed in a secure manner from a private subnet to a public-facing monitoring agent, achieving a clear segregation of private subnet and public facing components. Further, circuit-breaker logic is included for preventing failure during updating DNS addresses during the re-routing process.
