Detailed Description

template<class Scalar>
class Thyra::DefaultSpmdVectorSpace< Scalar >

Concrete implementation of an SPMD vector space subclass which creates DefaultSpmdVector and DefaultSpmdMultiVector objects.

This is a simple but yet fully general and functional concrete subclass of SpmdVectorSpaceBase that returns DefaultSpmdMultiVector objects from createMembers() and DefaultSpmdVector objects from createMember().

See the function initialize() that describes the different kinds of distributions this class can handle.

Definition at line 69 of file Thyra_DefaultSpmdVectorSpace_decl.hpp.

Member Function Documentation

template<class Scalar >

RCP< DefaultSpmdVectorSpace< Scalar > > Thyra::DefaultSpmdVectorSpace< Scalar >::create ( )

static

Create with weak ownership to self.

Definition at line 58 of file Thyra_DefaultSpmdVectorSpace_def.hpp.

template<class Scalar >

void Thyra::DefaultSpmdVectorSpace< Scalar >::initialize ( const Ordinal dim )

Initialize a serial space.

Parameters

dim	[in] Gives the dimension of the vector space.

Equivalent to calling this->initialize(Teuchos::null,dim,dim)

Definition at line 67 of file Thyra_DefaultSpmdVectorSpace_def.hpp.

template<class Scalar >

void Thyra::DefaultSpmdVectorSpace< Scalar >::initialize	(	const RCP< const Teuchos::Comm< Ordinal > > &	comm,
		const Ordinal	localSubDim,
		const Ordinal	globalDim,
		const bool	isLocallyReplicated = `false`
	)

Initialize an SPMD space.

Parameters

comm	[in] The communicator. This object must be maintained by the client the entire time that `this` is in use.
localSubDim	[in] The number of elements in the local process. This number can be different in every process.
globalDim	[in] Gives the number of global elements in the vector if `globalDim > 0`. If `globalDim < 0` then the global dimension is determined by the above argument `localSubDim` but requires a global communication to do so (i.e. `Spmd_Allreduce()`).

Preconditions:

localSubDim > 0
globalDim != 0
[comm.get() != NULL && globalDim > 0] globalDim >= localSubDim

Postconditions:




this->getComm().get() == comm.get() 

this->localSubDim() == localSubDim 

[comm.get() == NULL] this->dim() == localSubDim 

[comm.get() != NULL && globalDim > 0] this->dim() == globalDim 

[comm.get() != NULL && globalDim < 0] this->dim() == sum(localSubDim[i],i=0...numProc-1)

This function supports three different types of use-cases:




comm.get()==NULL : Serial (i.e. single process) vectors where this->dim() == localSubDim.



comm.get()!=NULL && globalDim < 0 : Distributed-memory vectors where this->dim() is equal to the sum of the localSubDim arguments in each process. This will result in a call to Spmd_Allreduce() inside of this function.



comm.get()!=NULL && globalDim > 0 : Distributed-memory vectors where this->dim() returns globalDim. This will not result in a call to Teuchos::reduceAll() inside this function and therefore the client had better be sure that globalDim is consistent with localSubDim in each process.



comm.get()!=NULL && globalDim == localSubDim : Locally-replicated distributed-memory vectors where this->dim() == globalDim == localSubDim.

Definition at line 76 of file Thyra_DefaultSpmdVectorSpace_def.hpp.

template<class Scalar >

void Thyra::DefaultSpmdVectorSpace< Scalar >::uninitialize ( )

Set to an uninitialized state.

Postconditions:

this->getComm().get() == NULL
this->localSubDim() == 0
this->dim() == 0

Definition at line 100 of file Thyra_DefaultSpmdVectorSpace_def.hpp.

bool Thyra::DefaultSpmdVectorSpace< Scalar >::hasInCoreView	(	const Range1D &	rng,
		const EViewType	viewType,
		const EStrideType	strideType

Returns true if all the elements in rng are in this process.
