AUTOMATIC CLUSTERING FOR SELF-ORGANIZING GRIDS

A method for clustering of nodes for a task, and cluster so provided comprising an automatically partitioned a set of nodes having a branched hierarchy of subsets based at least on a relative distance according to at least one node characteristic distance metric, each subset having a communication node, each node within the subset being adapted to communicate control information with the communication node, and the communication nodes of respective subnets which are hierarchically linked, being configured to communicate control information with each other; and a set of output preferred nodes for allocation of portions of a task, wherein the output set of preferred nodes is dependent on both the hierarchy and the task.
