org.ow2.proactive.topology.descriptor.TopologyDescriptor

org.ow2.proactive.topology.descriptor.SingleHostDescriptor

All Implemented Interfaces:

Serializable

@PublicAPI
public class SingleHostExclusiveDescriptor
extends SingleHostDescriptor

This descriptor allows to select nodes on the single hosts exclusively. The host with selected nodes will be reserved for the user.

By specifying this descriptor in ResourceManager.getAtMostNodes user may get more nodes than it asked for due to the fact that total capacity of hosts is bigger (even thought the resource manager tries to find the optimal host minimizing the waist of resources), namely

if user requested k nodes - the machine with exact capacity will be selected if exists - the machine with bigger capacity will be selected if exists. The capacity of the selected machine will be the closest to k. - the machine with smaller capacity than k will be selected. In this case the capacity of selected host will be the biggest among all other.
