    Associates this vertex with a slot sharing group for scheduling. Different vertices in the same slot sharing group can run one subtask each in the same slot.
    
    Parameters:
    
    grp - The slot sharing group to associate the vertex with.
  - getSlotSharingGroup
```
public SlotSharingGroup getSlotSharingGroup()
```
    Gets the slot sharing group that this vertex is associated with. Different vertices in the same slot sharing group can run one subtask each in the same slot. If the vertex is not associated with a slot sharing group, this method returns null.
    
    Returns:
    
    The slot sharing group to associate the vertex with, or null, if not associated with one.
  - setStrictlyCoLocatedWith
```
public void setStrictlyCoLocatedWith(AbstractJobVertex strictlyCoLocatedWith)
```
    Tells this vertex to strictly co locate its subtasks with the subtasks of the given vertex. Strict co-location implies that the n'th subtask of this vertex will run on the same parallel computing instance (TaskManager) as the n'th subtask of the given vertex. NOTE: Co-location is only possible between vertices in a slot sharing group. NOTE: This vertex must (transitively) depend on the vertex to be co-located with. That means that the respective vertex must be a (transitive) input of this vertex.
    
    Parameters:
    
    strictlyCoLocatedWith - The vertex whose subtasks to co-locate this vertex's subtasks with.
    
    Throws:
    
    IllegalArgumentException - Thrown, if this vertex and the vertex to co-locate with are not in a common slot sharing group.
