Detailed Description

Compute root step that corresponds to te::Stage::compute_root.

Member Function Documentation

ApplyToSchedule()

void tvm::auto_scheduler::ComputeRootStepNode::ApplyToSchedule	(	Array< te::Stage > *	stages,
		StageToAxesMap *	stage_to_axes
	)		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.

ApplyToState()

void tvm::auto_scheduler::ComputeRootStepNode::ApplyToState

(

State *

state

)

const

Apply the current step to State.

Parameters

state

A mutable pointer to state, which will be updated.

Note

After compute_root, we need careful dependency analysis to compute the accurate bound information. However, it is relatively expensive and complicated, so we just fill "None" as bound for the newly created iterators. Call ComputeDAG::InferBound on the updated state if you need the complete bound information.

PrintAsPythonAPI()

String tvm::auto_scheduler::ComputeRootStepNode::PrintAsPythonAPI	(	Array< te::Stage > *	stages,
		StageToAxesMap *	stage_to_axes
	)		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.

Returns

Python schedule code.

TVM_DECLARE_FINAL_OBJECT_INFO()

tvm::auto_scheduler::ComputeRootStepNode::TVM_DECLARE_FINAL_OBJECT_INFO	(	ComputeRootStepNode	,
		StepNode
	)

WriteToRecord()

void tvm::auto_scheduler::ComputeRootStepNode::WriteToRecord ( dmlc::JSONWriter *  writer ) const

finalvirtual

Serialize the current step record to JSONWriter.

Parameters

writer

The output JSONWriter.

Implements tvm::auto_scheduler::StepNode.
