Member Function Documentation

execute()

int exatn::runtime::TalshNodeExecutor::execute ( numerics::TensorOpCreate &  op, TensorOpExecHandle *  exec_handle  )

overridevirtual

Executes the tensor operation found in a DAG node asynchronously, returning the execution handle in exec_handle that can later be used for testing for completion of the operation execution. Returns an integer error code (0:Success).

Implements exatn::runtime::TensorNodeExecutor.

getLocalTensor()

std::shared_ptr< talsh::Tensor > exatn::runtime::TalshNodeExecutor::getLocalTensor ( const numerics::Tensor &  tensor, const std::vector< std::pair< DimOffset, DimExtent >> &  slice_spec  )

overridevirtual

Returns a local copy of a given tensor slice.

Implements exatn::runtime::TensorNodeExecutor.

initialize()

void exatn::runtime::TalshNodeExecutor::initialize ( )

overridevirtual

Explicitly initializes the underlying numerical service, if needed

Implements exatn::runtime::TensorNodeExecutor.

sync()

bool exatn::runtime::TalshNodeExecutor::sync ( TensorOpExecHandle  op_handle, int *  error_code, bool  wait = false  )

overridevirtual

Synchronizes the execution of a previously submitted tensor operation.

Implements exatn::runtime::TensorNodeExecutor.
