Abstract:
A system and computer program product for system care for a computing device. In one embodiment, a process includes analyzing one or more software and hardware components of the computing device by a system care program of the computing device, analyzing system health of the computing device based on the one or more software and hardware components based on at least one of status and settings of the one or more software and hardware components, and analyzing performance of the computing device based on the one or more software and hardware components based on signature profiles of the one or more software and hardware components The process may also include determining one or more solutions for the computing device by the system care program based on the system health and performance of the computing device, and displaying a report including the one or more solutions.
Abstract:
A digital diagnostic system employs signature analysis for locating faults at the system, module, or circuit component level in electronic equipment. Predetermined correct signatures and diagnostic decision tree information for a particular device under test are stored in system memory. The diagnostic system exercises the device under test to generate signatures which are obtained at various predetermined test points and electronically compared with a stored signature. From the diagnostic decision tree information, a troubleshooting sequence is automatically established which leads directly to a faulty module or component. In-circuit microprocessor emulation may be utilized to generate one or more of the signature signals.
Abstract:
Die Erfindung betrifft ein Verfahren zur parallelen Verarbeitung von Daten in einem Rechnersystem mit mehreren Rechnereinheiten und einer diesen nachgeordneten Votereinrichtung. Um eine sichere Datenverarbeitung mit vergleichsweise geringem Aufwand durchführen zu können, werden die Daten (D) nach ihrer Speicherung jeder Rechnereinheit (K1 bis K4) zugeführt, und es wird in den Rechnereinheiten (K1 bis K4) jeweils für sich eine Berechnungssignatur (BS1 bis BS4) bei jedem Rechnerzyklus unter Verwendung von befehlsweise berücksichtigten Speicheradressen und jeweils zugeordnetem Registerwert ermittelt. Die ermittelten Berechnungssignaturen (BS1 bis BS4) der Rechnereinheiten (K1 bis K4) werden der Votereinrichtung (V) zugeführt, und die Votereinrichtung (V) signalisiert bei einer Übereinstimmung von Berechnungssignaturen (BS1 bis BS4) der mehreren Rechnereinheiten (K1 bis K4) eine identische Datenverarbeitung. Die Erfindung betrifft auch ein Rechnersystem mit mehreren Rechnereinheiten und einer diesen nachgeordneten Votereinrichtung zur parallelen Verarbeitung von Daten.
Abstract:
La présente invention concerne un procédé et un dispositif d'aide à l'optimisation et la parallélisation de code d'une application. Le procédé s'exécute sur un ordinateur et consiste à comparer une portion de code représentant un point chaud d'une l'application à une pluralité de versions de code non optimisées pour déterminer une corrélation avec au moins une version de code non optimisée. Puis le procédé permet de générer à partir de la version de code non optimisée, des prédictions de performance pour différentes architectures et selon différents modèles de programmation parallèle pour ledit point chaud.
Abstract:
A system and method for data replication is described. A destination storage system receives a message from a source storage system as part of a replication process. The message includes an identity of a first file, information about where the first file is stored in the source storage system, a name of a first data being used by the first file and stored at a first location of the source storage system, and a fingerprint of the first data. The destination storage system determines that a mapping database is unavailable or inaccurate, and accesses a fingerprint database using the fingerprint of the first data received with the message to determine whether data stored in the destination storage system has a fingerprint identical to the fingerprint of the first data.
Abstract:
The invention relates to a data processing method, server and product for backing up and restoring data in a processor that prepares for a system shutdown, the method comprising receiving an instruction given by a user to backup a user-specified software program; finding the user-specified software program and data that are relevant to the user-specified software program, and creating a package including the user-specified software program and the data; backing up a package and adding a BACKUP tag to the package; obtaining the user-specified backup package with the BACKUP tag; the user-specified software program from the user-specific backup package; and recovering the data that are relevant to the user-specified software program after the user-specified software program runs normally.
Abstract:
An approach is provided to apply a virtual machine (VM) image to a computer system. In the approach, implemented by an information handling system, a detection is made that a current VM image executing on the computer system is experiencing a problem. In response, prior VM images are analyzed, with each of the prior VM images being an image that was previously executed on the computer system. Based on the analysis, one of the prior VM images is selected and the selected image is used to replace the current VM image on the computer system.
Abstract:
Embodiments are directed to locating and restoring backed up items using a custom schema and to efficiently transferring recovery data. In an embodiment, a computer system defines a schema that provides data search and retrieval among backup data sets. The schema stores searchable attributes for each database item and leverages a file system to store file system metadata for the data items of the backup sets. The computer system receives a request to find data items among the backup data sets and accesses the schema to determine, from the stored searchable attributes, which recovery points among the backup data sets include the requested data items. The computer system also restores the requested data items from the determined recovery point within the backup data sets.
