A multiprocessor computer system includes processing element nodes interconnected with physical communication links in an n-dimensional topology. A flow controlled virtual channel has virtual channel buffers assigned to each physical communication link to store packets containing information to be transferred between the processing element nodes. A non-flow controlled virtual maintenance channel has maintenance channel buffers assigned to each physical communication link to store packets of maintenance information to be transferred between the processing element nodes. The virtual maintenance channel is assigned a higher priority for accessing the physical communication links than the flow controlled virtual channel.
Un système informatique multiprocesseur comprend des noeuds en interconnexion avec des liaisons physiques de communication dans une topologie n-dimensionnelle. Un canal virtuel commandé en débit possède des tampons de canal virtuel qui sont attribués à chaque liaison physique de communication afin de mémoriser les paquets contenant l'information à transférer entre les noeuds. Un canal virtuel de maintenance non commandé en débit possède des tampons de canal de maintenance qui sont attribués à chaque liaison physique de communication afin de mémoriser les paquets contenant l'information de maintenance à transférer entre les noeuds. Ce canal virtuel de maintenance possède une attribution de priorité d'accès aux liaisons physiques de communication plus importante que celle du canal virtuel commandé en débit.
