Title
(EN) EMBEDDING RINGS ON A TOROID COMPUTER NETWORK
(FR) INCORPORATION D'ANNEAUX SUR UN RÉSEAU INFORMATIQUE TOROÏDAL
Abstract
(EN) A computer comprising a plurality of interconnected processing nodes arranged in a toroid configuration in which multiple layers of interconnected nodes are arranged along an axis; each layer comprising a plurality of processing nodes connected in a ring in a non axial plane by at least an intralayer respective set of links between each pair of neighbouring processing nodes, the links in each set adapted to operate simultaneously; wherein each of the processing nodes in each layer is connected to a respective corresponding node in each adjacent layer by an interlayer link to form respective rings along the axis; the computer programmed to provide a plurality of embedded one-dimensional logical paths and to transmit data around each of the embedded one-dimensional paths in such a manner that the plurality of embedded one- dimensional logical paths operate simultaneously, each logical path using all processing nodes of the computer in a sequence.
(FR) Un ordinateur comprend une pluralité de nœuds de traitement interconnectés agencés selon une configuration toroïdale dans laquelle de multiples couches de nœuds interconnectés sont agencées le long d'un axe; chaque couche comprenant une pluralité de nœuds de traitement reliés en un anneau dans un plan non axial par au moins un ensemble respectif de liaisons intracouche entre chaque paire de nœuds de traitement voisins, les liaisons dans chaque ensemble étant conçues pour fonctionner simultanément; chacun des nœuds de traitement dans chaque couche étant connecté à un nœud correspondant respectif dans chaque couche adjacente par une liaison inter-couches pour former des anneaux respectifs le long de l'axe; l'ordinateur étant programmé pour fournir une pluralité de chemins logiques unidimensionnels intégrés et pour transmettre des données autour de chacun des chemins unidimensionnels intégrés de telle manière que la pluralité de chemins logiques unidimensionnels intégrés fonctionnent simultanément, chaque chemin logique utilisant tous les nœuds de traitement de l'ordinateur dans une séquence.
