BelosLinProb() [2/3]

template<class T , class MV , class OP >

concepts::BelosLinProb< T, MV, OP >::BelosLinProb

(

Teuchos::RCP< const Teuchos::Comm< int > >

comm

)

Copies the informations of a concepts::SparseMatrix into a Tpetra::CrsMatrix and sets it to the Operator of the problem.

If started parallel this method should just be used by the threads with id != 0. If started sequentiell use the other Constructor.

@waring The thread with id 0 must be called with BelosLinProb(concepts::SparseMatrix<T>& sparse, Teuchos::RCP<const Teuchos::Comm<int> > comm) otherwise the recieve operation in this method will cause a DEADLOCK.

Definition at line 323 of file belosLinProb.hh.

BelosLinProb() [3/3]

template<class T , class MV , class OP >

concepts::BelosLinProb< T, MV, OP >::BelosLinProb	(	concepts::SparseMatrix< T > &	sparse,
		Teuchos::RCP< const Teuchos::Comm< int > >	comm
	)

Copies the informations of a concepts::SparseMatrix into a Tpetra::CrsMatrix and sets it to the operator of the problem.

If started parallel this method should just be used by the thread with id 0. All other threads must use BelosLinProb(Teuchos::RCP<const Teuchos::Comm<int> > comm), they recieve the informations of the seriell object concepts::SparseMatrix via this method

Warning

if the other threads do not call BelosLinProb(Teuchos::RCP<const Teuchos::Comm<int> > comm) the send() instruction in this constructor will cause a DEADLOCK.

void concepts::BelosLinProb< T, MV, OP >::setConceptsRHS	(	const Vector< T > &	rhs,

Copies the informations of a concepts::Vector into a Tpetra::Multivector and sets it to the rhs vector of the problem.

If started parallel this method should just be used by the thread with id 0. All other threads must use setRHS(Teuchos::RCP<const Teuchos::Comm<int> > comm), they recieve the informations of the seriell object concepts::Vector via this method
