Constructor & Destructor Documentation

◆ DatabaseNode()

tvm::meta_schedule::DatabaseNode::DatabaseNode ( ffi::String mod_eq_name = "structural" )

explicit

Constructor.

Parameters

mod_eq_name

A string to specify the module equality testing and hashing method. It must be one of the followings:

"structural": Use StructuralEqual/Hash
"ignore-tensor": Same as "structural", but ignore tensor raw data during equality testing and hashing.
"anchor-block": Apply equality testing and hashing on the anchor block extracted from a given module. The "ignore-tensor" varint is used for the extracted blocks or in case no anchor block is found. For the definition of the anchor block, see tvm/tir/analysis.h.

◆ ~DatabaseNode()

virtual tvm::meta_schedule::DatabaseNode::~DatabaseNode ( )

virtual

Default destructor.

Member Function Documentation

◆ CommitTuningRecord()

virtual void tvm::meta_schedule::DatabaseNode::CommitTuningRecord ( const TuningRecord & record )

pure virtual

Add a tuning record to the database.

Parameters

record The tuning record to be added.

Implemented in tvm::meta_schedule::PyDatabaseNode.

◆ CommitWorkload()

virtual Workload tvm::meta_schedule::DatabaseNode::CommitWorkload ( const IRModule & mod )

pure virtual

Look up or add workload to the database if missing.

Parameters

mod	The IRModule to be searched for or added.

Returns: The workload corresponding to the given IRModule.

Implemented in tvm::meta_schedule::PyDatabaseNode.

◆ DumpPruned()

void tvm::meta_schedule::DatabaseNode::DumpPruned ( Database destination )

Prune the database and dump it a given database.

Parameters

destination The destination database to be dumped to.

◆ GetAllTuningRecords()

virtual ffi::Array<TuningRecord> tvm::meta_schedule::DatabaseNode::GetAllTuningRecords ( )

pure virtual

Get all tuning records from the database.

Returns: An Array of all the tuning records in the database.

Implemented in tvm::meta_schedule::PyDatabaseNode.

◆ GetModuleEquality()

const ModuleEquality& tvm::meta_schedule::DatabaseNode::GetModuleEquality ( ) const

inline

Return a reference to the owned module equality method instance.

◆ GetTopK()

virtual ffi::Array<TuningRecord> tvm::meta_schedule::DatabaseNode::GetTopK	(	const Workload &	workload,
		int	top_k
	)

pure virtual

Get the top K valid tuning records of given workload from the database.

Parameters

workload	The workload to be searched for.
top_k	The number of top records to be returned.

Returns: An array of top K tuning records for the given workload.

Implemented in tvm::meta_schedule::PyDatabaseNode.

◆ HasWorkload()

virtual bool tvm::meta_schedule::DatabaseNode::HasWorkload ( const IRModule & mod )

pure virtual

Check if the database has the given workload.

Parameters

	)

virtual

Query the best IRModule of the given workload from the database.

Parameters

mod	The IRModule to be searched for.
target	The target to be searched for.
workload_name	The name of the workload to be searched for.

Returns: The IRModule in the best IRModule of the given workload; std::nullopt if not found.

Reimplemented in tvm::meta_schedule::PyDatabaseNode.

◆ QuerySchedule()

virtual ffi::Optional<tir::Schedule> tvm::meta_schedule::DatabaseNode::QuerySchedule	(	const IRModule &	mod,
		const Target &	target,
		const ffi::String &	workload_name
	)

virtual
