Processing can be performed in parallel, and even if there are multiple units, the cost can be kept much lower than that of a single information processing device with the latest and high specifications. It can achieve a processing speed that is not so inferior to one information processing device, and uses multiple low-spec PCs that have already been dropped.

Stored identically By doing so, it becomes possible to handle these multiple information processing devices, for example, personal computers, as one parallel distributed processing system. At this time, the multiple personal computers can sufficiently process even if they are not high-speed. Can be done at high speed.
  • the processing is started by storing the program recorded on the recording medium in each of a plurality of information processing devices connected to be capable of transmitting and receiving signals. Until the completion of the processing, the indicator and the processor do not share the CPU between the processing and other processing, and the CPU can be occupied only by the processing. Processing can be performed at a higher speed as compared with the program recorded on the recording medium of No. 3, so that processing can be performed at a higher speed even with a low-spec computer.

Abstract

L'invention concerne un système de traitement parallèle réparti destiné à traiter une grande quantité de données rapidement à faible coût avec des spécifications de basse performance. Le système de traitement parallèle réparti (1) comprend des appareils de traitement d'informations (ordinateurs personnels A0-A7) comprenant chacun au moins une UC, une mémoire ROM, une mémoire RAM ainsi qu'un dispositif de stockage connecté de manière à transmettre et à recevoir des signaux. Un appareil de traitement d'informations, qui génère des signaux de traitement représentant les contenus à traiter par les appareils de traitement d'informations (ordinateurs personnels A1-A7) et l'affectation des contenus aux appareils de traitement d'informations et qui transmet les signaux aux autres appareils de traitement d'informations (ordinateurs personnels A1-A7), est déterminé comme étant l'unité de commande (ordinateur personnel A0). Les autres appareils de traitement d'informations, lesquels reçoivent le signal de traitement, sont déterminés comme étant des processeurs (ordinateurs personnels A1-A7). Les processeurs (ordinateurs personnels A1-A7) détiennent le même programme de traitement pour un traitement parallèle et réparti.
