1. A method for data transport, in a network of at least three data processing nodes, from a source node to at least one destination node, said method comprising the step of: transferring said data from said source node to at least one target node wherein said transfer is via remote direct memory access operation from specific locations within source node memory to specific target locations within target memory locations and wherein said transfer is initiated at a node which is neither said source node nor said at least one target node, in which the initiating node sends a request to a communications adapter on said source node requesting that a remote DMA transfer be executed with said data target node.
