Orchestrator plugins define how a Job orchestrates the dispatching of executions to multiple nodes.

The default behavior is to dispatch based on these Job configuration values:

• Threadcount: how many nodes to process in parallel
• Rank attribute: which node attribute to use to sort the nodes (default is the node name.)
  • Rank ascending/descending: whether to sort ascending or descending

An Orchestrator plugin can choose its own logic for how many and what order to process the nodes.
