A multinode activation and termination method and system A method and system is provided for invoking multiple parallel instances of the same node. First, a multinode is defined that allows for multiple parallel activation of the node. At run time, a determination is made of the number of nodes to be activated based on an activation rule. The multinodes are then executed. Each multinode can be provided with different input data for execution, thereby allowing one to fine tune the input and attributes of each node. A termination rule is utilized to determine when the execution of the multinode is completed. When the execution of the multinode is complete, a successor node is then executed. When the execution of the multinode is not complete, processing continues on the multinode.
