A method using for performing a scatter-type data distribution among a cluster of computational devices. A number of nodes (equal to a value Cg, the number of tree generator channels) are initially generated, each connected to an initial generator, to create respective initial root nodes of an initial tree structure. Data is transmitted from the initial generator to each of the initial root nodes. Cg root nodes, each connected to a respective new generator, are generated to create respective roots of Cg newly generated tree structures. Each of the tree structures is expanded by generating Ct (the number of communication channels per node in each tree structure) new nodes connected to each node generated in each previous step. Data is then transmitted to each of the new nodes from an immediately preceding one of the nodes, and from each new generator to an associated root node.
