    摘要： Maintenance modes of operation of a multiprocessing vector supercomputer system are disclosed. The modes allow diagnostics to run on a failed portion of the system while simultaneously allowing user tasks to run in a degraded performance mode. This is accomplished by assigning a processor or a group of processors to run diagnostics on an assigned portion of memory, while the operating system and user tasks are run in the remaining processors in the remaining portion of memory. In this manner, the diagnostics can isolate the problem without requiring complete shut down of the user task, while at the same time protecting the integrity of the operating system. The result is significantly reduced preventive maintenance down time, more efficient diagnosis of hardware failures, and a corresponding increase in user task run time.

    摘要： A ring computer network system having a communication controller for controlling the receipt and sending of packets or messages at each client computer. The interface associated with each client computer includes a send message buffer and a receive message buffer. The send message buffer has a send message buffer counter which increments upwardly is response to messages being received from the client computer for sending on the ring network. The communication controller sends messages from the send buffer until the send message buffer counter reaches the address or a value associated with the last received message. Similarly, the receive message buffer includes a receive message buffer counter which increments as each message is received to a receive message buffer counter value. The receive message buffer is emptied until the receive message buffer counter value is reached. The receive buffer can also have a foreground portion and a background portion. The send buffer can also have a background portion and a foreground portion of memory. The communication controller continually switches between the foreground and background portions of memory and redesignates each memory portion after the switch. The communications controller can also recognize priority schemes for the messages.

    摘要： L'invention concerne les modes de fonctionnement entretien d'un système de superordinateur vectoriel à multitraitement. Les modes permettent d'effectuer des diagnostics sur une partie du système en panne tout en permettant simultanément l'exécution de tâches d'utilisateur en mode d'exécution dégradé. Ces modes peuvent être mis en oeuvre par affectation d'un processeur ou d'un groupe de processeurs à l'exécution de diagnostics sur une partie de mémoire affectée, tandis que le système d'exploitation et les tâches d'utilisateur sont pris en charge dans les processeurs restants se trouvant dans la partie restante de la mémoire. Ainsi, les diagnostics peuvent isoler le problème sans nécessiter un arrêt total de l'exécution de la tâche d'un utilisateur tout en protégeant en même temps l'intégrité du système d'exploitation. On peut ainsi réduire notablement la durée d'indisponibilité due à un entretien préventif, obtenir un diagnostic plus efficace des pannes du matériel informatique, et augmenter d'autant le temps d'exécution des tâches d'utilisateur.
