Title
(EN) AN EARLY START MODE METHOD AND APPARATUS
(FR) PROCEDE ET APPAREIL A MODE DE MISE EN ROUTE SANS RETARD
Abstract
(EN)
A method and apparatus for loosely coupling a plurality of processors in a multiprocessor system to perform a coordinated task. The coordination of the task is implemented by an early start mode data transfer apparatus which coordinates the reading and writing of data files into and out of the data buffer (101) of the control unit (100) so that a data file can be written into the data buffer (101) while another file is concurrently being read out of the data buffer (101). Thus, both the host computer (130) and the associated tape drive units (140) can be active at the same time that data files are being read from or written into the data buffer (100) of the tape control unit (101).

Le procédé et l'appareil décrits servent à effectuer le couplage lâche de plusieurs processeurs dans un système à processeurs multiples pour réaliser une tâche coordonnée. La coordination de la tâche est assurée par un appareil de transfert de données à mode de mise en route sans retard, qui coordonne l'introduction et l'extraction des fichiers de données à l'intérieur et hors de la mémoire de données tampon (101) de l'unité de commande (100). Ainsi, un fichier de données peut être introduit dans la mémoire de données tampon (101) pendant qu'un autre fichier est simultanément extrait de la mémoire de données tampon (101). L'ordinateur central (130) et les unités d'entraînement de bande associées (140) peuvent alors fonctionner en même temps que se produit l'extraction ou l'introduction des fichiers de données à l'intérieur ou hors de la mémoire de données tampon (100) de l'unité de commande de bande (101).
