Member Function Documentation

◆ extractDependencyFreeNode()

bool exatn::runtime::TensorExecState::extractDependencyFreeNode ( VertexIdType * node_id )

Extracts a dependency-free node from the list. Returns FALSE if no such node exists.

◆ extractExecutingNode()

bool exatn::runtime::TensorExecState::extractExecutingNode ( VertexIdType * node_id )

Extracts an executed DAG node from the list.

◆ getFrontNode()

VertexIdType exatn::runtime::TensorExecState::getFrontNode ( ) const

Returns the front node id.

◆ getTensorEpochNodes()

const std::vector< VertexIdType > * exatn::runtime::TensorExecState::getTensorEpochNodes	(	const Tensor &	tensor,
		int *	epoch
	)

Returns the list of nodes participating in the current R/W epoch: epoch > 0: This is the number of reads in the current Read epoch; epoch = -1: This is the single write in the current Write epoch.

◆ getTensorUpdateCount()

std::size_t exatn::runtime::TensorExecState::getTensorUpdateCount ( const Tensor & tensor )

Returns the current outstanding update count on the tensor in the DAG.

◆ progressFrontNode()

bool exatn::runtime::TensorExecState::progressFrontNode ( VertexIdType node_executed )

Moves the front node forward if the given DAG node is the next node after the front node and it has just been executed to completion.

◆ registerDependencyFreeNode()

void exatn::runtime::TensorExecState::registerDependencyFreeNode ( VertexIdType node_id )

Registers a DAG node without dependencies.

◆ registerExecutingNode()

void exatn::runtime::TensorExecState::registerExecutingNode ( VertexIdType node_id )

Registers a DAG node as being executed.

◆ registerTensorRead()

int exatn::runtime::TensorExecState::registerTensorRead	(	const Tensor &	tensor,
		VertexIdType	node_id
	)

Registers a new read on a Tensor. Returns the current epoch R/W counter.

◆ registerTensorWrite()

int exatn::runtime::TensorExecState::registerTensorWrite	(	const Tensor &	tensor,
		VertexIdType	node_id
	)

Registers a new write on a Tensor. Returns the current epoch R/W counter.

◆ registerWriteCompletion()

std::size_t exatn::runtime::TensorExecState::registerWriteCompletion ( const Tensor & tensor )

Registers completion of an outstanding write on a Tensor. Returns the updated outstanding update count on the Tensor.
