Checks that there are no duplicate uniqueIds.

Here is the call graph for this function:

◆ _computeFacesUniqueIdsParallelV1()

void Arcane::mesh::FaceUniqueIdBuilder::_computeFacesUniqueIdsParallelV1 ( )

private

Calculates the unique numbers for each face in parallel.

In addition to numbering, it determines the owning sub-domain of each face, considering that a face belongs to the same sub-domain as the cell behind it (or to the current sub-domain for a boundary cell).

Todo: optimize the algorithm so as not to have to create an array sized to the total number of cells in the mesh (by proceeding in several steps)

Todo: find a more optimal algorithm for searching for the owner of each face to balance communications.
