Detailed Description

Class containing processor-to-processor mapping information.

We store mapping from the bits-to-send to the complete starting list (subXXXMap) and from the received bits to their location in the new list (constructXXXMap).

Note: Schedule is a list of processor pairs (one send, one receive. One of them will be myself) which forms a scheduled (i.e. non-buffered) exchange. See distribute on how to use it. Note2: number of items sent on one processor have to equal the number of items received on the other processor.

To aid constructing these maps there are the constructors from global numbering, either with or without transforms.

Constructors using compact numbering: layout is

all my own elements first (whether used or not)
followed by used-only remote elements sorted by remote processor. So e.g 4 procs and on proc 1 the compact table will first have all globalIndex.localSize() elements from proc1 followed by used-only elements of proc0, proc2, proc3. The constructed mapDistributeBase sends the local elements from and receives the remote elements into their compact position. compactMap[proci] is the position of elements from proci in the compact map. compactMap[myProcNo()] is empty since trivial addressing.

It rewrites the input global indices into indices into the constructed data.

When constructing from components optionally a 'flip' on the maps can be specified. This will interpret the map values as index+flip, similar to e.g. faceProcAddressing. The flip will only be applied to fieldTypes (scalar, vector, .. triad)

bool hasFlipAddressing ( const labelUList & map )

Test for flip addressing, where flips are encoded as negative indices and non-flips are encoded as positive non-zero indices.

Exits early on the first detected zero or negative, which makes this more efficient than testing min(map) < 0.

Note: may return a false negative (ie, no flips detected) even when flip addressing is used, but the local map does not contain any flipped elements

bool hasFlipAddressing ( const labelListList & maps )

Test for flip addressing, where flips are encoded as negative indices and non-flips are encoded as positive non-zero indices.

◆ compactLocalData() [1/3]

void compactLocalData	(	const bitSet &	allowedLocalElems,

Compact send/receive maps based on selection of originating local (send) elements.

Determines and removes the correspondingly unneeded elements in the send/receive maps. Only compacts the maps, does not change the local layout.

Parameters

allowedLocalElems	Permissible local mapped elements (true/false). Can be longer/shorter than actual number of mapped elements.
tag	The message tag
doRenumber	Apply oldToNew internally to renumber entries (uses renumberMap) and adjust the constructSize

Note: generally preferable to compact based on remote data (ie, the actual receiver)
