void OverlapMapping::keepTracksOfSourceIds	(	int	procId,

	)

This method keeps tracks of source ids to know in step 6 of main algorithm, which tuple ids to send away. This method incarnates item#1 of step2 algorithm.

void OverlapMapping::keepTracksOfTargetIds	(	int	procId,
		DataArrayInt *	ids
	)

This method keeps tracks of target ids to know in step 6 of main algorithm. This method incarnates item#0 of step2 algorithm.

		const DataArrayInt *	srcIds,
		int	srcProcId,
		const DataArrayInt *	trgIds,
		int	trgProcId
	)

This method stores from a matrix in format Target(rows)/Source(cols) for a source procId 'srcProcId' and for a target procId 'trgProcId'. All ids (source and target) are in format of local ids.

void OverlapMapping::prepare	(	const std::vector< std::vector< int > > &	procsInInteraction,
		int	nbOfTrgElems
	)

'procsInInteraction' gives the global view of interaction between procs. In 'procsInInteraction' for a proc with id i, is in interaction with procs listed in procsInInteraction[i].

This method is in charge to send matrixes in AlltoAll mode. After the call of this method 'this' contains the matrixST for all source elements of the current proc

void OverlapMapping::computeDenoConservativeVolumic ( int nbOfTuplesTrg )

Compute denominators.

void OverlapMapping::multiply	(	const MEDCouplingFieldDouble *	fieldInput,
		MEDCouplingFieldDouble *	fieldOutput
	)			const

This method performs a transpose multiply of 'fieldInput' and put the result into 'fieldOutput'. 'fieldInput' is expected to be the sourcefield and 'fieldOutput' the targetfield.

void OverlapMapping::transposeMultiply	(	const MEDCouplingFieldDouble *	fieldInput,
		MEDCouplingFieldDouble *	fieldOutput
	)

This method performs a transpose multiply of 'fieldInput' and put the result into 'fieldOutput'. 'fieldInput' is expected to be the targetfield and 'fieldOutput' the sourcefield.

void OverlapMapping::serializeMatrixStep0ST	(	const int *	nbOfElemsSrc,
		int *&	bigArr,
		int *	count,
		int *	offsets,
		int *	countForRecv,
		int *	offsetsForRecv
	)			const

This method performs step #0/3 in serialization process.

Parameters:

	count	tells specifies nb of elems to send to corresponding proc id. size equal to _group.size().
	offsets	tells for a proc i where to start serialize#0 matrix. size equal to _group.size().
	nbOfElemsSrc	of size _group.size(). Comes from previous all2all call. tells how many srcIds per proc contains matrix for current proc.

		double *&	bigArrD,

This method performs step#1 and step#2/3. It returns the size of expected array to get allToAllV.

	)

This is the last step after all2Alls for matrix exchange. _the_matrix_st is the final matrix :

The first entry is srcId in current proc.
The second is the pseudo id of source proc (correspondance with true id is in attribute _the_matrix_st_source_proc_id and _the_matrix_st_source_ids)
the third is the srcId in the pseudo source proc

void OverlapMapping::finishToFillFinalMatrixST ( )

This method should be called when all remote matrix with sourceProcId==thisProcId have been retrieved and are in 'this->_the_matrix_st' and 'this->_the_matrix_st_target_proc_id' and 'this->_the_matrix_st_target_ids'. This method finish the job of filling 'this->_the_matrix_st' and 'this->_the_matrix_st_target_proc_id' by putting candidates in 'this->_matrixes_st' into them.

void OverlapMapping::prepareIdsToSendST ( )

This method performs the operation of target ids broadcasting.

void OverlapMapping::updateZipSourceIdsForFuture ( )

This method should be called immediately after _the_matrix_st has been filled with remote computed matrix put in this proc for Matrix-Vector. This method computes for these matrix the minimal set of source ids corresponding to the source proc id.
