template<class Exec = SExec>
void	moveLocalPieces (const std::vector< VofMoveJob > &mv)
	H-4(e), host: every collected `movePiece` copy in one launch per chunk of `kVofBlockBatch` (piece, component) pairs, rows inside, through a by-value job table – instead of one MDRange3 per piece per component.

void	gatherColour (std::vector< VofBlock > &blocks, SField cLocal) override
	Fill every MASTER block's INNER colour from the caller's colour patch (the mirror of `scatterColourMax`).

void	scatterColourMax (std::vector< VofBlock > &blocks, SField cLocal) override
	UNION the masters' inner colour into the caller's local colour patch: zero the inner region, then `C = max(C, C_block)` cell by cell (TBFsolver's UNPACK_MAX).

void	scatterForceSum (std::vector< VofBlock > &blocks, SField fx, SField fy, SField fz) override
	SUM every master block's CSF face force into the caller's three face-force patches (TBFsolver's UNPACK_SUM, `VOF.f90::computeSurfaceTension`): overlapping markers ADD their forces, which is what makes two touching bubbles push on the fluid twice and not once.

void	scatterColourSum (std::vector< VofBlock > &blocks, SField sLocal) override
	`S = sum_k C_k` (vof_overlap_design §5.6): the colour scatter with UNPACK_SUM.

void	migrateColour (std::vector< VofBlock > &blocks, const std::vector< int > &oldMaster) override
	Move a block's colour from its old master to its new one after a re-assignment (rung W1 item a).

long	migrateBytes () const

long	migrateMessages () const

SField	buffer (long n)
	Reusable device buffer of exactly `n` doubles, handed out in REQUEST ORDER — two live messages of the same size must not be the same View, so the pool is keyed by the request sequence (reset at the head of every transfer) and not by the size.

void	gatherFaceVelHost (std::vector< VofBlock > &blocks, int ghost)

void	scatterColourMaxHost (std::vector< VofBlock > &blocks, SField cLocal)

void	syncTable (std::vector< VofBlock > &blocks) override
	Replicate the (possibly re-centred) boxes so every rank's table agrees again.

◆ init()

		std::array< bool, 3 >	per,
		std::vector< VofBox >	rankBox,
		int	rank
	)

inline

Parameters

rankBox the owned inner box of EVERY rank, in global cells (from the flow BlockDecomposer; a single element covering the grid when serial)

Definition at line 158 of file block_exchange.hpp.

◆ setRankBoxes()

void peclet::flow::vof::VofBlockExchange::setRankBoxes ( std::vector< VofBox > rankBox )

inline

Re-bind the owned inner box of every rank WITHOUT disturbing the communicator or the local patch.

The gather/scatter pieces are computed from these boxes, so a decomposition that MOVES (dynamic load balancing: Solver::redistribute) must push the new ones through here — otherwise every piece still addresses the previous partition's rank blocks.

Definition at line 172 of file block_exchange.hpp.

◆ setPatch()

void peclet::flow::vof::VofBlockExchange::setPatch	(	Patch	p,
		SField	uf,
		SField	vf,
		SField	wf
	)

inline

The local face velocity, in the ADVECTOR's high-face convention (i.e.

already bridged with vof::copyFaceVelocity), on the local patch.

Definition at line 181 of file block_exchange.hpp.

inline

block -> patch, combined with op (0 = max, 1 = sum).

The patch's INNER region is zeroed first: both combines start from an empty field (UNPACK_MAX's empty union is pure gas; UNPACK_SUM's is no force), so a cell no marker covers reads exactly 0.

gatherLocal (UNPACK_SUM only; the CSF force, doc/vof_step_performance_design.md §5.9): the pieces of the blocks this rank masters are not combined block by block but GATHERED in one launch – per patch cell, the blocks in block order, each adding its value if its box holds the cell. That is the per-block combine's addition sequence (0, then the local masters in block order, then the received pieces), so the sum is the same double.

	)

inline

The local half of a gatherLocal UNPACK_SUM: every patch INNER cell written (so no zeroing pass is needed) with 0 + the values of the blocks this rank masters whose box holds it, in block order.

A block box is at most one period long on a periodic axis, so a patch cell maps to at most one block-local cell – the one vofBuildPieces maps it to. More than kVofBlockBatch blocks: later chunks continue each cell's sum from the value the previous chunk left, which is the same addition sequence.

inlineoverridevirtual

Fill every MASTER block's faceU/V/W over its EXTENDED box, from the face velocity the ranks own.

Cells outside a non-periodic domain come from the ghost layers of the rank whose box touches that domain face — the doubles the global-field advector consumes there. They are NOT a clamp fill: uf(i) is the HIGH face of cell i, so the LOW domain face (a wall's normal velocity, an inflow's datum) sits at global index -1. A zero-gradient copy of index 0 put the first interior face's velocity on a no-slip wall, and every marker with colour in the wall-adjacent layer then gained or lost volume through the wall (bubble column, 2026-09-25: up to 1e-5 of a marker per step).

SUM every master block's CSF face force into the caller's three face-force patches (TBFsolver's UNPACK_SUM, VOF.f90::computeSurfaceTension): overlapping markers ADD their forces, which is what makes two touching bubbles push on the fluid twice and not once.

Reusable device buffer of exactly n doubles, handed out in REQUEST ORDER — two live messages of the same size must not be the same View, so the pool is keyed by the request sequence (reset at the head of every transfer) and not by the size.

The request sequence of a step is deterministic, so after the first few steps nothing is allocated at all; an allocation per message would otherwise dominate the device-vs-host packing comparison.
