Methods and systems for parallel computation of an algorithm using a plurality of nodes configured as a Howard Cascade. A home node of a Howard Cascade receives a request from ahost system to compute an algorithm identified in the request. The request is distributed to processing nodes of the Howard Cascade in a time sequence order in a manner to minimize the time to so expand the Howard Cascade. The participating nodes then perform the designated portion of the algorithm in parallel. Partial results from each node are agglomerated upstream to higher nodes of the structure and then returned to the host system. The nodes each include a library of stored algorithms accompanied by data template information defining partitioning of the data used in the algorithm among the number of participating nodes.

L'invention concerne des systèmes et procédés de traitement parallèle d'un algorithme utilisant une pluralité de noeuds configurés sous la forme d'une cascade d'Howard. Un noeud de départ de la cascade de Howard reçoit une requête provenant d'un système hôte pour calculer un algorithme identifié dans la requête. La requête est distribuée dans les noeuds de traitement de la cascade d'Howard dans un ordre de séquence temporelle de manière à réduire au minimum le temps afin d'élargir la cascade d'Howard. Les noeuds participants traitent ensuite en parallèle la partie désignée de l'algorithme. Les résultats partiels de chaque noeud sont agglomérés en aval des noeuds supérieurs de la structure puis retournés au système hôte. Chacun des noeuds comprend une bibliothèque d'algorithmes stockés accompagnés d'une information de motif de données définissant la partition des données utilisées dans l'algorithme parmi les nombreux noeuds participants.
