Detailed Description

template<class LO = default_lo, class GO = default_go, class NO = default_no>
class FEDD::BlockMap< LO, GO, NO >

Block Variant of Map class.

This becomes relevant for block systems and when we attempt to use monolithic preconditioning or solving to determine the merged map of system.

Template Parameters

LO	The local ordinal type. The is the index type for local indices
GO	The global ordinal type. The is the index type for global indices
NO	The Kokkos Node type. This would allow for performance portibility when using Kokkos. Currently, this is not used.

This becomes relevant for block systems and when we attempt to use monolithic preconditioning or solving to determine the merged map of system.

i.e. Stokes Problem:

0 | A B BlockMap->getBlock(0) of row-block 0

1 | B^T 0 BlockMap->getBlock(1) of row-block 1

Constructor & Destructor Documentation

BlockMap()

template<class LO, class GO, class NO>

FEDD::BlockMap< LO, GO, NO >::BlockMap

(

UN

size

)

Initializing block maps with the size of system (i.e. 2 for Stokes problem). As systems are distributed row-wise, block i corresponds to row-block i.

Parameters

size

of system

Member Function Documentation

addBlock()

template<class LO, class GO, class NO>

void FEDD::BlockMap< LO, GO, NO >::addBlock	(	MapConstPtr_Type	map,
		int	i )

Adding map to corresponding block i. Block i is row-wise distrubted according to the underlying map.

Parameters

map	local to global indexing of rows
i	block id

getComm()

template<class LO, class GO, class NO>

BlockMap< LO, GO, NO >::CommConstPtr_Type FEDD::BlockMap< LO, GO, NO >::getComm

(

)

Get underlying communicator.

Returns

comm_

getMergedMap()

template<class LO, class GO, class NO>

BlockMap< LO, GO, NO >::MapConstPtr_Type FEDD::BlockMap< LO, GO, NO >::getMergedMap

(

)

Getting merged map of block maps.

Returns

mergedMap
