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.

static |
Create with weak ownership to self.
Definition at line 58 of file Thyra_DefaultSpmdVectorSpace_def.hpp.
void Thyra::DefaultSpmdVectorSpace< Scalar >::initialize | ( | const Ordinal | dim | ) |
Initialize a serial space.
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.
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.
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
.
