Detailed Description

A state in the search process. It consists of the current loop structure and a list of transformation steps used to construct it. Each State corresponds to a specific schedule for its ComputeDAG.

◆ attach_map

AttachMap tvm::auto_scheduler::StateNode::attach_map

The attach relations of stages and iterators. This is used to track the compute at operation.

◆ concrete

bool tvm::auto_scheduler::StateNode::concrete

Indicate whether this state has unfilled tile sizes. A concrete state means that all tile sizes of the state is filled. Only concrete state can be apply to TVM schedule.

◆ current_compute_dag

Optional<ObjectRef> tvm::auto_scheduler::StateNode::current_compute_dag

The up-to-date ComputeDAG of this state. The default value is an empty NullOpt, meaning the dag of this state is the same as the original ComputeDAG in the SearchTask. Otherwise, the stored value is the up-to-date ComputeDAG for this state, meaning some steps (e.g., CacheReadStep/CacheWriteStep) have modified the ComputeDAG.

◆ stages

Array<Stage> tvm::auto_scheduler::StateNode::stages

Current stages and loop structures.

◆ transform_steps

Array<Step> tvm::auto_scheduler::StateNode::transform_steps

History transformation steps.
