Constructor & Destructor Documentation

◆ DatabaseNode()

tvm::meta_schedule::DatabaseNode::DatabaseNode ( 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-ndarray": Same as "structural", but ignore ndarray 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-ndarray" 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 )
