Detailed Description

Measurer that measures the time costs of tvm programs This class combines ProgramBuilder and ProgramRunner, and provides a simpler API.

Member Function Documentation

◆ Measure()

Array<MeasureResult> tvm::auto_scheduler::ProgramMeasurerNode::Measure	(	const SearchTask &	task,
		const SearchPolicy &	policy,
		const Array< MeasureInput > &	inputs,
		int	batch_size = `-1`
	)

Do measurement.

Parameters

task	The current SearchTask.
policy	The current SearchPolicy.
inputs	The inputs of measurement.
batch_size	Number of programs to be measured in one batch.

Returns: results The results of measurement.

◆ Reset()

void tvm::auto_scheduler::ProgramMeasurerNode::Reset ( )

Reset book keeping variables.

◆ SilentMeasure()

void tvm::auto_scheduler::ProgramMeasurerNode::SilentMeasure	(	const SearchTask &	task,
		const Array< MeasureInput > &	inputs,
		Array< MeasureResult > *	results
	)

Do measurement silently. This API will not print the measure results to screen.

Parameters

task	The current SearchTask.
inputs	The MeasureInputs.
results	A pointer to a MeasureResult Array, this is used as output.

◆ TVM_DECLARE_FINAL_OBJECT_INFO()

tvm::auto_scheduler::ProgramMeasurerNode::TVM_DECLARE_FINAL_OBJECT_INFO	(	ProgramMeasurerNode	,
