Method for establishing communication routes between nodes of a computer cluster, corresponding computer program and computer cluster

摘要

A method includes obtaining the topology of a computer cluster, with first global numbers respectively assigned to the nodes thereof, and implementing, for each pair of nodes, an algorithm adapted for providing a communication route between the nodes, based on respective numbers of the nodes and the topology of the computer cluster. The method further includes selecting nodes and numbering the nodes in order to assign second global numbers thereto, which numbers are different from the first global numbers for at least one part of the selected nodes, the second global numbers of the selected nodes being successively separated by values each of which is different from the periodicity of each of at least one part of the communication links. Moreover, in order to implement the algorithm, the nodes are identified by the second global numbers thereof.
