Performances (informatique)En informatique, les performances énoncent les indications chiffrées mesurant les possibilités maximales ou optimales d'un matériel, d'un logiciel, d'un système ou d'un procédé technique pour exécuter une tâche donnée. Selon le contexte, les performances incluent les mesures suivantes : Un faible temps de réponse pour effectuer une tâche donnée Un débit élevé (vitesse d'exécution d'une tâche) L'efficience : faible utilisation des ressources informatiques : processeur, mémoire, stockage, réseau, consommation électrique, etc.
Optimizing compilerIn computing, an optimizing compiler is a compiler that tries to minimize or maximize some attributes of an executable computer program. Common requirements are to minimize a program's execution time, memory footprint, storage size, and power consumption (the last three being popular for portable computers). Compiler optimization is generally implemented using a sequence of optimizing transformations, algorithms which take a program and transform it to produce a semantically equivalent output program that uses fewer resources or executes faster.
Bien collectifEn économie publique, un bien collectif est un bien dont la consommation par un individu supplémentaire ne réduit pas la satisfaction des autres. Le bien collectif existant ou créé, est accessible à tous sans condition : comme l'air pur, une justice intègre et rapide, un réseau de téléphone qui fonctionne bien, une bonne route. Il existe aussi des services collectifs rendus par un bien privé tel que la radio ou les autoroutes. Les exemples typiques sont les forêts, les espaces maritimes de pêche, les nappes d'eau souterraines ou les systèmes d'irrigation.
Flat memory modelFlat memory model or linear memory model refers to a memory addressing paradigm in which "memory appears to the program as a single contiguous address space." The CPU can directly (and linearly) address all of the available memory locations without having to resort to any sort of bank switching, memory segmentation or paging schemes.
Data virtualizationData virtualization is an approach to data management that allows an application to retrieve and manipulate data without requiring technical details about the data, such as how it is formatted at source, or where it is physically located, and can provide a single customer view (or single view of any other entity) of the overall data. Unlike the traditional extract, transform, load ("ETL") process, the data remains in place, and real-time access is given to the source system for the data.
Shock mountA shock mount or isolation mount is a mechanical fastener that connects two parts elastically. They are used for shock and vibration isolation. Isolation mounts allow a piece of equipment to be securely mounted to a foundation and/or frame and, at the same time, allow it to float independently from the substrate. Shock mounts can be found in a wide variety of applications. Shock mounts can be used to isolate the foundation or substrate from the dynamics of the mounted equipment.
Manufacturing resource planningManufacturing resource planning (MRP II) is a method for the effective planning of all resources of a manufacturing company. Ideally, it addresses operational planning in units, financial planning, and has a simulation capability to answer "what-if" questions and is an extension of closed-loop MRP (Material Requirements Planning). This is not exclusively a software function, but the management of people skills, requiring a dedication to database accuracy, and sufficient computer resources.
