Detailed Description

template<typename Number>
class LinearAlgebra::TpetraWrappers::Vector< Number >

This class implements a wrapper to the Trilinos distributed vector class Tpetra::Vector. This class is derived from the LinearAlgebra::VectorSpaceVector class and requires Trilinos to be compiled with MPI support.

Tpetra uses Kokkos for thread-parallelism and chooses the execution and memory space automatically depending on Kokkos configuration. The priority is ranked from highest to lowest:

GPU backend
host parallel backend
Kokkos::Serial

In case Kokkos was configured with GPU support, this class performs its actions on the GPU. In particular, there is no need for manually synchronizing memory between host and device.

Constructor & Destructor Documentation

◆ Vector() [1/3]

template<typename Number >

LinearAlgebra::TpetraWrappers::Vector< Number >::Vector ( )

Constructor. Create a vector of dimension zero.

◆ Vector() [2/3]

template<typename Number >

LinearAlgebra::TpetraWrappers::Vector< Number >::Vector ( const Vector< Number > & V )

Copy constructor. Sets the dimension and the partitioning to that of the given vector and copies all elements.

◆ Vector() [3/3]

template<typename Number >

LinearAlgebra::TpetraWrappers::Vector< Number >::Vector	(	const IndexSet &	parallel_partitioner,
		const MPI_Comm	communicator
	)

explicit

This constructor takes an IndexSet that defines how to distribute the individual components among the MPI processors. Since it also includes information about the size of the vector, this is all we need to generate a parallel vector.

Member Function Documentation

		const MPI_Comm	communicator,
		const bool	omit_zeroing_entries = `false`
	)

Reinit functionality. This function destroys the old vector content and generates a new one based on the input partitioning. The flag omit_zeroing_entries determines whether the vector should be filled with zero (false) or left untouched (true).

◆ reinit() [2/2]

template<typename Number >

virtual void LinearAlgebra::TpetraWrappers::Vector< Number >::reinit	(	const VectorSpaceVector< Number > &	V,
		const bool	omit_zeroing_entries = `false`
	)

Change the dimension to that of the vector V. The elements of V are not copied.

Implements LinearAlgebra::VectorSpaceVector< Number >.

◆ operator=() [1/2]

template<typename Number >

Vector & LinearAlgebra::TpetraWrappers::Vector< Number >::operator= ( const Vector< Number > & V )

Copy function. This function takes a Vector and copies all the elements. The Vector will have the same parallel distribution as V.

◆ operator=() [2/2]

template<typename Number >

virtual Vector & LinearAlgebra::TpetraWrappers::Vector< Number >::operator= ( const Number s )

	)

overridevirtual

Imports all the elements present in the vector's IndexSet from the input vector V. VectorOperation::values operation is used to decide if the elements in V should be added to the current vector or replace the current elements. The last parameter can be used if the same communication pattern is used multiple times. This can be used to improve performance.

Implements LinearAlgebra::VectorSpaceVector< Number >.

◆ import()

template<typename Number >

virtual void LinearAlgebra::TpetraWrappers::Vector< Number >::import	(	const ReadWriteVector< Number > &	V,
		VectorOperation::values	operation,

Implements LinearAlgebra::VectorSpaceVector< Number >.

◆ sadd()

template<typename Number >

virtual void LinearAlgebra::TpetraWrappers::Vector< Number >::sadd	(	const Number	s,
		const Number	a,
		const VectorSpaceVector< Number > &	V
	)

overridevirtual

Scaling and simple addition of a multiple of a vector, i.e. this = s(*this)+a*V.

Implements LinearAlgebra::VectorSpaceVector< Number >.

◆ scale()

template<typename Number >

virtual void LinearAlgebra::TpetraWrappers::Vector< Number >::scale ( const VectorSpaceVector< Number > & scaling_factors )

overridevirtual

Scale each element of this vector by the corresponding element in the argument. This function is mostly meant to simulate multiplication (and immediate re-assignment) by a diagonal scaling matrix. The vectors need to have the same layout.

Implements LinearAlgebra::VectorSpaceVector< Number >.

◆ add_and_dot()

template<typename Number >

virtual Number LinearAlgebra::TpetraWrappers::Vector< Number >::add_and_dot	(	const Number	a,
		const VectorSpaceVector< Number > &	V,
		const VectorSpaceVector< Number > &	W
	)

overridevirtual

Performs a combined operation of a vector addition and a subsequent inner product, returning the value of the inner product. In other words, the result of this function is the same as if the user called

this->add(a, V);

return_value = *this * W;

LinearAlgebra::TpetraWrappers::Vector::add

virtual void add(const Number a) override

The reason this function exists is that this operation involves less memory transfer than calling the two functions separately. This method only needs to load three vectors, this, V, W, whereas calling separate methods means to load the calling vector this twice. Since most vector operations are memory transfer limited, this reduces the time by 25% (or 50% if W equals this).

The vectors need to have the same layout.

For complex-valued vectors, the scalar product in the second step is implemented as \(\left<v,w\right>=\sum_i v_i \bar{w_i}\).

virtual size_type LinearAlgebra::TpetraWrappers::Vector< Number >::size ( ) const

overridevirtual

Return the global size of the vector, equal to the sum of the number of locally owned indices among all processors.

Implements LinearAlgebra::VectorSpaceVector< Number >.

◆ locally_owned_size()

template<typename Number >

size_type LinearAlgebra::TpetraWrappers::Vector< Number >::locally_owned_size ( ) const

Return the local size of the vector, i.e., the number of indices owned locally.

◆ get_mpi_communicator()

template<typename Number >

MPI_Comm LinearAlgebra::TpetraWrappers::Vector< Number >::get_mpi_communicator ( ) const

Return the underlying MPI communicator.

◆ locally_owned_elements()

template<typename Number >

virtual ::IndexSet LinearAlgebra::TpetraWrappers::Vector< Number >::locally_owned_elements ( ) const

overridevirtual

Return an index set that describes which elements of this vector are owned by the current processor. As a consequence, the index sets returned on different processors if this is a distributed vector will form disjoint sets that add up to the complete index set. Obviously, if a vector is created on only one processor, then the result would satisfy

vec.locally_owned_elements() == complete_index_set(vec.size())

complete_index_set

IndexSet complete_index_set(const IndexSet::size_type N)

Definition index_set.h:1089

Implements LinearAlgebra::VectorSpaceVector< Number >.

	)		const

overridevirtual

template<typename Number >

virtual std::size_t LinearAlgebra::TpetraWrappers::Vector< Number >::memory_consumption ( ) const

overridevirtual

Return the memory consumption of this class in bytes.

Implements LinearAlgebra::VectorSpaceVector< Number >.

◆ subscribe()

void Subscriptor::subscribe	(	std::atomic< bool > *const	validity,
		const std::string &	identifier = `""`
	)		const

inherited

Subscribes a user of the object by storing the pointer validity. The subscriber may be identified by text supplied as identifier.

Definition at line 136 of file subscriptor.cc.

◆ unsubscribe()

void Subscriptor::unsubscribe	(	std::atomic< bool > *const	validity,
		const std::string &	identifier = `""`
	)		const

inherited

Unsubscribes a user from the object.

Note: The identifier and the validity pointer must be the same as the one supplied to subscribe().

Definition at line 156 of file subscriptor.cc.

◆ n_subscriptions()

unsigned int Subscriptor::n_subscriptions ( ) const

inlineinherited

Return the present number of subscriptions to this object. This allows to use this class for reference counted lifetime determination where the last one to unsubscribe also deletes the object.

Definition at line 300 of file subscriptor.h.

◆ list_subscribers() [1/2]

template<typename StreamType >

void Subscriptor::list_subscribers ( StreamType & stream ) const

inlineinherited

List the subscribers to the input stream.

Definition at line 317 of file subscriptor.h.

◆ list_subscribers() [2/2]

void Subscriptor::list_subscribers ( ) const

inherited

List the subscribers to deallog.

Definition at line 204 of file subscriptor.cc.

◆ serialize()

template<class Archive >

void Subscriptor::serialize	(	Archive &	ar,
		const unsigned int	version
	)

inlineinherited

Read or write the data of this object to or from a stream for the purpose of serialization using the BOOST serialization library.

This function does not actually serialize any of the member variables of this class. The reason is that what this class stores is only who subscribes to this object, but who does so at the time of storing the contents of this object does not necessarily have anything to do with who subscribes to the object when it is restored. Consequently, we do not want to overwrite the subscribers at the time of restoring, and then there is no reason to write the subscribers out in the first place.

Definition at line 309 of file subscriptor.h.

◆ check_no_subscribers()

void Subscriptor::check_no_subscribers ( ) const

privatenoexceptinherited

Check that there are no objects subscribing to this object. If this check passes then it is safe to destroy the current object. It this check fails then this function will either abort or print an error message to deallog (by using the AssertNothrow mechanism), but will not throw an exception.

Note: Since this function is just a consistency check it does nothing in release mode.; If this function is called when there is an uncaught exception then, rather than aborting, this function prints an error message to the standard error stream and returns.

Definition at line 53 of file subscriptor.cc.

Definition at line 462 of file trilinos_tpetra_vector.h.

◆ counter

std::atomic<unsigned int> Subscriptor::counter

mutableprivateinherited

Store the number of objects which subscribed to this object. Initially, this number is zero, and upon destruction it shall be zero again (i.e. all objects which subscribed should have unsubscribed again).

The creator (and owner) of an object is counted in the map below if HE manages to supply identification.

We use the mutable keyword in order to allow subscription to constant objects also.

This counter may be read from and written to concurrently in multithreaded code: hence we use the std::atomic class template.

Definition at line 219 of file subscriptor.h.

◆ counter_map

std::map<std::string, unsigned int> Subscriptor::counter_map

mutableprivateinherited

In this map, we count subscriptions for each different identification string supplied to subscribe().

std::vector<std::atomic<bool> *> Subscriptor::validity_pointers

mutableprivateinherited

In this vector, we store pointers to the validity bool in the SmartPointer objects that subscribe to this class.

Definition at line 241 of file subscriptor.h.

◆ object_info

const std::type_info* Subscriptor::object_info

mutableprivateinherited

Pointer to the typeinfo object of this object, from which we can later deduce the class name. Since this information on the derived class is neither available in the destructor, nor in the constructor, we obtain it in between and store it here.

Definition at line 249 of file subscriptor.h.

◆ mutex

std::mutex Subscriptor::mutex

staticprivateinherited

A mutex used to ensure data consistency when printing out the list of subscribers.

Definition at line 271 of file subscriptor.h.
