Abstract: The described embodiments provide a processor that executes vector instructions. In the described embodiments, the processor initializes an architectural fault-status register (FSR) and a shadow copy of the architectural FSR by setting each of N bit positions in the architectural FSR and the shadow copy of the architectural FSR to a first predetermined value. The processor then executes a first first-faulting or non-faulting (FF/NF) vector instruction. While executing the first vector instruction, the processor also executes one or more subsequent FF/NF instructions. In these embodiments, when executing the first vector instruction and the subsequent vector instructions, the processor updates one or more bit positions in the shadow copy of the architectural FSR to a second predetermined value upon encountering a fault condition.

Abstract: Requests for retrieval of data items from another data processing apparatus include embedded objects having executable class functions for performing operations at the target data processing apparatus. This has the advantages of the request implicitly sending data as well as requesting data and allows the request to perform a test on data within an object (such as a comparison with parameters of the request to determine whether the request may be satisfied).

Abstract: Technologies are described herein for differentiating normal operation of an application program from error conditions to predict, diagnose, and recover from application failures. Access to resources by the application program is monitored, and resource access events are logged.

In addition, sequences of resource access events that deviate from the established resources access patterns are correlated with an error condition based on a temporal proximity to the time of occurrence of the error to provide diagnostic information regarding the error.

Abstract: A data processing device acquires a first parameter value of a hardware component, and calculates a first prediction value of the first parameter using a prediction algorithm. If a difference of the first prediction value and the first parameter falls within a deviation range, the first parameter value is determined as a real value and is stored. Otherwise, the device acquires a second parameter value of the hardware component that follows the first parameter value, and calculates a second prediction value of the second parameter value. If a difference between the second prediction value and the second parameter value falls with a second deviation range, the first parameter value is determined as a real value and is stored. Otherwise, the first parameter value is determined as a false value and is abandoned.

Abstract: A novel and useful method of creating signatures for use in classifying failures of software programs in general and circuit design simulation tests in particular. Upon failure of a processor simulation test, the method of the present invention creates a signature comprising the sequence of source code commands executed shortly before the failure. The created signature, along with the reported error message together provides a functional grouping of the tests into groups of similar failures. After executing a suite of processor simulation test programs the resulting signatures are classified by their respective error messages and signatures. The results are then analyzed to pinpoint any program errors, or (in the case of processor design tests) design flaws causing the simulation test failures.

Abstract: A client device in a distributed system may include a timer for timing a request time duration substantially including a period of time that the client device is waiting for results to be received via a network from a server in response to a request sent by the client device. A network interface may receive a value of a service time duration from the server. The service time duration may correspond to time that the server spent servicing the request. A processor may subtract the service time duration from the request time duration to thereby calculate a difference time duration, and automatically control the network interface to issue one or more alert messages to a network operation center (NOC) via the network when the difference time duration is greater than a difference time threshold. The difference time threshold may be determined according to a type of the request.

Abstract: Perceived corruptions encountered on file system volumes, and which cannot be initially remedied online, are processed to verify whether they are true, existing volume data structure corruptions or, alternatively, false positives. Upon the verification of one or more of a volume's corruptions, error scanning is performed to check for, and attempt to remedy online, all the existing corruptions on the volume. Subsequent to error scanning processing, if one or more verified corruptions continue to exist on a file system volume, at file system boot up time spot corruption correction is performed to attempt to remedy the existing, verified corruptions on the volume. Spot corruption correction is performed to attempt to correct verified data structure corruptions on a volume of the file system while the volume is maintained offline for the time necessary to attempt to correct its prior identified corruptions.

Abstract: Data structure errors, or corruptions, identified during, e.g., normal computing device system processing, file system processing or user access processing, are verified prior to the file system identifying the error for offline correction or notifying the user or system administrator a data structure error exists. Identified data structure corruptions are verified while the file system volumes are maintained online and otherwise accessible to other processing tasks and user access. Verified data structure corruptions are logged for further corrective processing. Data structure corruptions that cannot be verified, i.e., false positives, are not further processed and are not identified to file system administrators or users as corruptions, freeing the file system to concentrate on normal processing and true, verifiable errors.

Abstract: Dissatisfaction variables track inputs made by an end user at an information handling system that are associated with end user dissatisfaction regarding the operation of the information handling system, such as corrective actions, so that an alert issues if a dissatisfaction variable changes by a predetermined amount over a predetermined time period.

For example, an increase in end user forced shutdowns of the information handling system indicates end user dissatisfaction with the information handling system, such as repeated freezes of the operating system so that performing a timely diagnostics will improve end user satisfaction and proactively correct and impending system failure.
