Abstract
(EN)
The present invention effectively utilizes a computation resource by allocating the computation resource, in a state-corresponding manner, to a process that shares the computation resource with other processes and a process that occupies the computation resource. Execution control allows a processor core allocated to a storage control process to be occupied by the storage control process and a processor core allocated to an application process to be shared with other processes, the execution control changing the number of processor cores allocated to the storage control process on the basis of I/O information indicating the I/O state.
(FR)
L'invention utilise efficacement une ressource de calcul en attribuant la ressource de calcul, en fonction de l'état, à un procédé qui partage la ressource de calcul avec d'autres processus et un processus qui mobilise la ressource de calcul. La commande d'exécution permet qu'un cœur de processeur attribué à un processus de commande de stockage soit mobilisé par le processus de commande de stockage et qu'un cœur de processeur attribué à un processus d'application soit partagé avec d'autres processus, la commande d'exécution modifiant le nombre de cœurs de processeur attribués au processus de commande de stockage d'après les informations E/S indiquant l'état E/S.
(JA)
 計算資源を他のプロセスと共有するプロセスと、計算資源を占有するプロセスとに対し、状態に応じて計算資源を割り当てることにより、計算資源を有効に利用する。実行制御は、ストレージ制御プロセスに割り当てられたプロセッサコアを、ストレージ制御プロセスに占有させ、実行制御は、アプリケーションプロセスに割り当てられたプロセッサコアを、他のプロセスと共有させ、実行制御は、I/Oの状態を示すI/O情報に基づいて、ストレージ制御プロセスに割り当てられたプロセッサコアの数を変更する。
