class boost::serialization::access

Detailed Description

Factory for creating PETSc vectors distributed across processes.

Replacement for the vector creation portions of DistributedVector (which was implemented using static methods and data), the factory class allows several patterns of PETSc vector length (and distributions among processes) to co-exist.

All vectors created by a factory instance will have the same base size and parallelisation pattern.

Definition at line 50 of file DistributedVectorFactory.hpp.

Constructor & Destructor Documentation

DistributedVectorFactory::DistributedVectorFactory ( Vec vec )

Set the problem with an existing PETSc vector -- must have stride=1.

Parameters:

vec

is a PETSc vector which we want to use as the pattern for future vectors produced by this factory

Definition at line 75 of file DistributedVectorFactory.cpp.

References CalculateOwnership().

DistributedVectorFactory::DistributedVectorFactory	(	unsigned	size,
		PetscInt	local = `PETSC_DECIDE`
	)

Set the problem size specifying distribution over local processor.

Parameters:

	size	the problem size
	local	defaults to PETSc's default

Definition at line 82 of file DistributedVectorFactory.cpp.

References CalculateOwnership(), CheckForPetsc(), and PetscTools::CreateVec().

DistributedVectorFactory::DistributedVectorFactory ( DistributedVectorFactory * pOriginalFactory )

Constructor for use in archiving. Note that this constructor is only called when the number of processes is different from the original. Therefore, the orignal local node ownership cannot be used, and a new even partition will be applied.

Parameters:

pOriginalFactory

see mpOriginalFactory

Definition at line 94 of file DistributedVectorFactory.cpp.

References CalculateOwnership(), PetscTools::CreateVec(), GetProblemSize(), and mpOriginalFactory.

DistributedVectorFactory::DistributedVectorFactory	(	unsigned	lo,
		unsigned	hi,
		unsigned	size,
		unsigned	numProcs = `PetscTools::GetNumProcs()`
	)

Constructor intended for use in archiving. Allows complete manual specification of the factory.

Parameters:

	lo	first index owned by this process
	hi	one beyond last index owned by this process
	size	total size of vectors
	numProcs	the number of processes expected (defaults to the current number)

DistributedVectorFactory::~DistributedVectorFactory ( )

Destructor deletes mpOriginalFactory if it exists
