Detailed Description

Cache read step that corresponds to te::Schedule::cache_read.

Note: Cache read step adds an extra stage to the original ComputeDAG, an up-to-date ComputeDAG will be stored in State's current_compute_dag.

Member Function Documentation

◆ ApplyToSchedule()

te::Tensor tvm::auto_scheduler::CacheReadStepNode::ApplyToSchedule	(	Array< te::Stage > *	stages,
		StageToAxesMap *	stage_to_axes,
		te::Schedule *	schedule
	)		const

Apply the current step to tvm.schedule.

Parameters

stages	The list of current stages
stage_to_axes	A map that maps stage ot all its iterators.
schedule	A mutable pointer to a te::Schedule.

Returns: The output Tensor of the new added stage.

◆ ApplyToState()

int tvm::auto_scheduler::CacheReadStepNode::ApplyToState	(	State *	state,
		const ComputeDAG &	dag
	)		const

Apply the current step to State.

Parameters

state	A mutable pointer to state, which will be updated.
dag	The original ComputeDAG of this state.

Returns: The index of the new added stage.

◆ PrintAsPythonAPI()

String tvm::auto_scheduler::CacheReadStepNode::PrintAsPythonAPI	(	Array< te::Stage > *	stages,
		StageToAxesMap *	stage_to_axes,
		te::Schedule *	schedule
	)		const

Print the current step as equivalent python schedule API.

Parameters

stages	The list of current stages
stage_to_axes	A map that maps stage ot all its iterators.
schedule	A mutable pointer to a te::Schedule.

Returns: Python schedule code.

◆ TVM_DECLARE_FINAL_OBJECT_INFO()
