Active Slot Occupancy

This counter represents the occupancy of the shader engine's active task slots. Tasks assigned to active slots can be scheduled in for execution immediately. When a task in an active slot encounters a data dependency, it is de-scheduled and another task takes its place.

A high percentage indicates that the shader engine processing pipelines are well utilized. A low percentage may indicate:

• High data dependency: If a large number of tasks in the available slots are resolving data dependencies, there may not be a sufficient number of ready tasks to schedule into the active slots.

• Low available slot occupancy: If available slot occupancy is low, there may be an insufficient number of ready tasks to populate the active slots.
