> Input location preferences will be considered for each SharedSlot when
> allocating a physical slot for it. Input location preferences of a SharedSlot
> will be the merge of input location preferences of all the tasks to run in
> this SharedSlot.
> Inter-ExecutionSlotSharingGroup input location preferences can be respected
> in this way for ExecutionSlotSharingGroups belonging to different bulks. If
> ExecutionSlotSharingGroups belong to the same bulk, the input location
> preferences are ignored because of possible cyclic dependencies. Later, we
> can optimise this case when the declarative resource management for reactive
> mode is ready.
> Intra-ExecutionSlotSharingGroup input location preferences will also be
> respected when creating ExecutionSlotSharingGroup(s) in
> DefaultSlotSharingStrategy.
