Title
(EN) CONTROLLING POWER CONSUMPTION IN MULTI-CORE ENVIRONMENTS
(FR) CONTRÔLE DE LA CONSOMMATION D'ÉNERGIE DANS DES ENVIRONNEMENTS MULTICŒURS
Abstract
(EN)
Systems and methods of enabling modulation of a frequency of a first core in a multi-core environment include logic to determine a power limit assigned to the first core, logic to determine a stall count of the first core, and logic to modulate the frequency of the first core based at least on the power limit assigned to the first core and the stall count of the first core. The first core is included in a first tile of a socket in the multi-core computer environment.
(FR)
Des systèmes et des procédés permettant la modulation d'une fréquence d'un premier cœur dans un environnement multicœurs comprennent une logique pour déterminer une limite de puissance affectée au premier cœur, une logique pour déterminer un décompte du premier score, et une logique pour moduler la fréquence du premier cœur d'après au moins la limite de puissance affectée au premier cœur et le décompte du premier cœur. Le premier cœur est inclus dans une première mosaïque d'une interface de connexion dans l'environnement informatique multicœurs.
