ScheduleA schedule or a timetable, as a basic time-management tool, consists of a list of times at which possible tasks, events, or actions are intended to take place, or of a sequence of events in the chronological order in which such things are intended to take place. The process of creating a schedule — deciding how to order these tasks and how to commit resources between the variety of possible tasks — is called scheduling, and a person responsible for making a particular schedule may be called a scheduler.
Hamiltonian path problemIn the mathematical field of graph theory the Hamiltonian path problem and the Hamiltonian cycle problem are problems of determining whether a Hamiltonian path (a path in an undirected or directed graph that visits each vertex exactly once) or a Hamiltonian cycle exists in a given graph (whether directed or undirected). Both problems are NP-complete.
Calcul distribuéUn calcul distribué, ou réparti ou encore partagé, est un calcul ou un traitement réparti sur plusieurs microprocesseurs et plus généralement sur plusieurs unités centrales informatiques, et on parle alors d'architecture distribuée ou de système distribué. Le calcul distribué est souvent réalisé sur des clusters de calcul spécialisés, mais peut aussi être réalisé sur des stations informatiques individuelles à plusieurs cœurs. La distribution d'un calcul est un domaine de recherche des sciences mathématiques et informatiques.
Fractional Fourier transformIn mathematics, in the area of harmonic analysis, the fractional Fourier transform (FRFT) is a family of linear transformations generalizing the Fourier transform. It can be thought of as the Fourier transform to the n-th power, where n need not be an integer — thus, it can transform a function to any intermediate domain between time and frequency. Its applications range from filter design and signal analysis to phase retrieval and pattern recognition.
Manycore processorManycore processors are special kinds of multi-core processors designed for a high degree of parallel processing, containing numerous simpler, independent processor cores (from a few tens of cores to thousands or more). Manycore processors are used extensively in embedded computers and high-performance computing. Manycore processors are distinct from multi-core processors in being optimized from the outset for a higher degree of explicit parallelism, and for higher throughput (or lower power consumption) at the expense of latency and lower single-thread performance.
Round-robin (informatique)thumb|upright=1.5|Exemple de planification de tâches en round-robin Le Round-robin (ou tourniquet) est un algorithme d'ordonnancement courant dans les systèmes d'exploitation adapté aux systèmes travaillant en temps partagés. Une petite unité de temps, appelé quantum de temps, est définie. La file d'attente est gérée comme une file circulaire. L'ordonnanceur parcourt cette file et alloue un temps processeur à chacun des processus pour un intervalle de temps de l'ordre d'un quantum au maximum.
