  • KCore: create connectivitiy cENNbrs: Elts - Number of neighbour elts
  • Vertex re-numbering using OpenMP (see KCore/Connect/prefixSum): cumulative sum with masked array elements set to 0
  • Version of selectExteriorElts without OpenMP
  • Version of selectExteriorElts using face hashing rather than cENNbrs
  • Draft version combining cENNbrs and hashing of faces of exterior elements only
  • Draft version of selectExteriorFaces using face hashing

Regressions (only topo, geometrically identical):
