@PublicAPI
public class NodeSet
extends ArrayList<org.objectweb.proactive.core.node.Node>

The set of nodes given by the resource manager for computations. The set may contain another collection of nodes (extra nodes) that basically are not intended to be used for computations but occupied by used according to the request. For example when 1 node is requested on a single host exclusively and there is no host available with a single node on it. In this case the resource manager may find another a host with bigger capacity and put all all nodes with were not requested explicitly into the extra nodes collection.
