Abstract: front page image
(EN)According to one embodiment of the present invention, a system for proportional share scheduling is provided, the system comprising: a reference type setting unit; a task generating unit for generating as many tasks as the number of saturation tasks, wherein some of the tasks are generated as target type tasks that generate input/output requests of target types from among one or more types, and the remaining part of the tasks are generated as reference type tasks that generate input/output requests of a reference type; a profiling unit for acquiring the bandwidth of a flash storage for the generated target type tasks and the reference type tasks; an exchange rate calculating unit for calculating an exchange rate on the basis of a sum bandwidth for the target type tasks and a sum bandwidth for the reference type tasks; and an input/output cost estimating unit for calculating the cost of the target type by multiplying the exchange rate by the cost of the reference type.
(FR)La présente invention concerne, selon un mode de réalisation, un système de planification de part proportionnelle, le système comprenant : une unité de réglage de type de référence; une unité de génération de tâches pour générer autant de tâches que le nombre de tâches de saturation, certaines des tâches étant générées en tant que tâches de type cible qui génèrent des demandes d'entrée/sortie de types cibles parmi un ou plusieurs types, et la partie restante des tâches étant générées en tant que tâches de type de référence qui génèrent des demandes d'entrée/sortie d'un type de référence; une unité de profilage pour acquérir la largeur de bande d'une mémoire flash pour les tâches de type cible générées et les tâches de type de référence; une unité de calcul de taux d'échange pour calculer un taux d'échange sur la base d'une largeur de bande de somme pour les tâches de type cible et d'une largeur de bande de somme pour les tâches de type de référence; et une unité d'estimation de coût d'entrée/sortie pour calculer le coût du type cible en multipliant le taux d'échange par le coût du type de référence.
(KO)본 발명의 일 실시예에 따르면, 기준 타입 설정부; 포화 태스크 수만큼 태스크를 생성하되, 일부는 상기 하나 이상의 타입들 중 목표 타입의 입출력 요청을 생성하는 목표 타입 태스크로 생성하고, 나머지 일부는 상기 기준 타입의 입출력 요청을 생성하는 기준 타입 태스크로 생성하는 태스크 생성부; 생성된 상기 목표 타입 태스크 및 상기 기준 타입 태스크에 대한 상기 플래시 스토리지의 대역폭을 획득하는 프로파일링부; 상기 목표 타입 태스크에 대한 합산 대역폭 및 상기 기준 타입 태스크에 대한 합산 대역폭에 기초하여, 교환비율을 산출하는 교환비율 산출부; 상기 교환비율을 상기 기준 타입의 비용에 곱하여 상기 목표 타입의 비용을 산출하는 입출력 비용 추정부; 를 포함하는 비례 지분 스케줄링 시스템이 제공된다.
