Abstract

Ce dispositif de traitement d'informations réalise : un premier processus qui stocke des objets à stocker dans un dispositif de stockage ; un deuxième processus qui lit, à partir du dispositif de stockage, les objets stockés dans le dispositif de stockage et génère un objet emballé dans lequel le ou les objets lus sont collectés ; un troisième processus qui stocke, dans le dispositif de stockage, l'objet emballé ; et un quatrième processus qui écrit l'objet emballé sur une bande magnétique. Lorsqu'une valeur de charge indiquant la charge d'E/S du dispositif de stockage est supérieure ou égale à une valeur de seuil prédéterminée, le dispositif de traitement d'informations réalise une commande pour arrêter uniquement le troisième processus parmi les premier à quatrième processus.
