Detailed Description

Helper class for replicating a PETSc vector.

Definition at line 45 of file ReplicatableVector.hpp.

Constructor & Destructor Documentation

ReplicatableVector::ReplicatableVector

(

)

Default constructor. Note that the vector will need to be resized before it can be used.

Definition at line 68 of file ReplicatableVector.cpp.

ReplicatableVector::ReplicatableVector

(

Vec

vec

)

Constructor taking in PETSc vector, which is immediately replicated into the internal data

Parameters

vec	a PETSc vector

Definition at line 76 of file ReplicatableVector.cpp.

References ReplicatePetscVector().

ReplicatableVector::ReplicatableVector

(

unsigned

size

)

Constructor to make a vector of given size.

Parameters

size	the size of the vector

Definition at line 85 of file ReplicatableVector.cpp.

References Resize().

ReplicatableVector::~ReplicatableVector

(

)

Default destructor. Remove PETSc context.

Definition at line 94 of file ReplicatableVector.cpp.

References RemovePetscContext().

unsigned ReplicatableVector::GetSize

(

)

Returns

the size of the vector.

double & ReplicatableVector::operator[]

(

unsigned

index

)

Access the vector.

Parameters

index

the index of the vector to return

Returns

reference to component of the vector

Definition at line 128 of file ReplicatableVector.cpp.

References mpData, and mSize.

void ReplicatableVector::RemovePetscContext ( )

private

Clear data. Used in resize method and destructor.

Definition at line 45 of file ReplicatableVector.cpp.

References PetscTools::Destroy(), mpData, mReplicated, mToAll, and PETSC_DESTROY_PARAM.

Referenced by Resize(), and ~ReplicatableVector().

void ReplicatableVector::Replicate	(	unsigned	lo,
		unsigned	hi
	)

Replicate this vector over all processes.

Each process knows its local part of the vector. This method shares that knowledge across all the processes.

Parameters

lo	The start of our ownership range
hi	One past the end of our ownership range

Definition at line 136 of file ReplicatableVector.cpp.

References PetscTools::Destroy(), GetSize(), mpData, and ReplicatePetscVector().

void ReplicatableVector::ReplicatePetscVector

(

Vec

vec

)

Replicate the given PETSc vector over all processes.

Each process knows its local part of the vector. This method shares that knowledge across all the processes, storing it in this object.

Our data vector will automatically be resized to fit the whole PETSc vector.

Parameters

vec	The PETSc vector to replicate.

void ReplicatableVector::Resize

(

unsigned

size

)

Resize the vector.

Parameters

size	The number of elements to allocate memory for.
