Detailed Description
Distributed Voronoi halo over core (migration Phase 6).
A Voronoi/power cell is fully determined by its local neighbourhood, so the distributed tessellation needs ONE ghost exchange and no iteration: decompose the periodic domain into blocks, gather every seed within the security radius of the block, tessellate owned+ghost locally, and keep the owned cells (they are bit-identical to the serial cells, since all their neighbours are present).
This wrapper reuses core for all of that — exactly the infrastructure the dem distributed step uses, and the C++ counterpart of the validated mpi/validate_voronoi.py recipe:
- peclet::core::decomp::BlockDecomposer<3> : ORB block ownership;
- peclet::core::halo::ParticleMigrator<3> : ownerOf() + periodic wrap;
- peclet::core::halo::ParticleHaloTopology<3> : gather ghost seeds within rcut and forward owner fields (global id, weight) onto the ghost copies.
Header-only host driver; requires MPI + core (PECLET_VORO_MPI build).
