Detailed Description

"Block" partitioning is the only one implemented now.

.. We rename it here to Box partitioner to avoid name space conflicts.

Member Function Documentation

real BoxPartitioner::getFactor	(	int	i,
		int	j
	)			const [inline, private]

real BoxPartitioner::getInvDistanceBetweenAtoms	(	int	i,
		int	j
	)			const [inline, private]

return distance between given pair of relevant atoms.

Arguments i and j specify the number of the atoms on the list of relevant atoms.

void BoxPartitioner::prepare	(	const std::vector< AtomicGrid > &	atoms,
		unsigned	noOfRelevantAtoms,
		const unsigned *	relevantAtoms,
		unsigned	pointCnt,
		const real *	gridPoints[3]
	)			[private]

unsigned BoxPartitioner::process	(	unsigned	atomNumber,
		const std::vector< AtomicGrid > &	atomGrids,
		int	noOfRelevantAtoms,
		const unsigned *	relevantAtoms,
		unsigned	batchLength,
		real *	coor[3],
		real *	w
	)

Applies the partitioning factors to the the grid points associated with given atom.

Parameters:

	atomNumber	index of the atom that the grid points are associated with, in the relevantAtoms array.
	atomGrids	the list of all atom grids.
	noOfRelevantAtoms	the number of atoms relevant for the box being processed. They need to be taken into account when computing the partitioning weights.
	relevantAtoms	the indices of the relevant atoms in the atomGrids vector.
	batchLength	number of the grid points the partitioning weights have to be computed for.
	coor	their cartesian coordinates. Will be modified if the grid point compression occurs.
	w	Their weights - they will be modified.

Returns:

new batch length after compression.
