Dispatch mode. The dispatch mode determines how the Load Balancer dispatches tasks. You can configure the Load Balancer to dispatch tasks in a simple round-robin fashion, in a round-robin fashion using node load metrics, or to the node with the most available computing resources.

Service level. Service levels establish dispatch priority among tasks that are waiting to be dispatched. You can create different service levels that a workflow developer can assign to workflows.

Resources. When the PowerCenter Integration Service runs on a grid, the Load Balancer can compare the resources required by a task with the resources available on each node. The Load Balancer dispatches tasks to nodes that have the required resources. You assign required resources in the task properties. You configure available resources using the Administrator tool or

CPU profile. In adaptive dispatch mode, the Load Balancer uses the CPU profile to rank the computing throughput of each CPU and bus architecture in a grid. It uses this value to ensure that more powerful nodes get precedence for dispatch.

Resource provision thresholds. The Load Balancer checks one or more resource provision thresholds to determine if it can dispatch a task. The Load Balancer checks different thresholds depending on the dispatch mode.
