Performance engineeringPerformance engineering encompasses the techniques applied during a systems development life cycle to ensure the non-functional requirements for performance (such as throughput, latency, or memory usage) will be met. It may be alternatively referred to as systems performance engineering within systems engineering, and software performance engineering or application performance engineering within software engineering.
Compacité (mathématiques)En topologie, on dit d'un espace qu'il est compact s'il est séparé et qu'il vérifie la propriété de Borel-Lebesgue. La condition de séparation est parfois omise et certains résultats demeurent vrais, comme le théorème des bornes généralisé ou le théorème de Tychonov. La compacité permet de faire passer certaines propriétés du local au global, c'est-à-dire qu'une propriété vraie au voisinage de chaque point devient valable de façon uniforme sur tout le compact.
Control tableControl tables are tables that control the control flow or play a major part in program control. There are no rigid rules about the structure or content of a control table—its qualifying attribute is its ability to direct control flow in some way through "execution" by a processor or interpreter. The design of such tables is sometimes referred to as table-driven design (although this typically refers to generating code automatically from external tables rather than direct run-time tables).
Predication (computer architecture)In computer architecture, predication is a feature that provides an alternative to conditional transfer of control, as implemented by conditional branch machine instructions. Predication works by having conditional (predicated) non-branch instructions associated with a predicate, a Boolean value used by the instruction to control whether the instruction is allowed to modify the architectural state or not. If the predicate specified in the instruction is true, the instruction modifies the architectural state; otherwise, the architectural state is unchanged.
