Class DifferentHostsExclusiveDescriptor

java.lang.Object

org.ow2.proactive.topology.descriptor.TopologyDescriptor

org.ow2.proactive.topology.descriptor.DifferentHostsExclusiveDescriptor

All Implemented Interfaces:

Serializable

@PublicAPI
public class DifferentHostsExclusiveDescriptor
extends TopologyDescriptor

This descriptor allows to select one node per host exclusively. Hosts 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 all machines is bigger.

The resource manager first will try to find hosts with only one node to optimize the utilization of resources. If there no such hosts (or their quantity is below required) it will continue looking for hosts with 2 nodes and so on. If number of hosts is not enough the found subset will be provided.
