On the Use of Space Filling Curves for Parallel Anisotropic Mesh Adaptation

  • Conference paper
Proceedings of the 18th International Meshing Roundtable

Abstract

Efficiently parallelizing a whole set of meshing tools, as required by an automated mesh adaptation loop, relies strongly on data localization to avoid memory access contention. In this regard, renumbering mesh items through a space filling curve (SFC), like Hilbert or Peano, is of great help and proved to be quite versatile. This paper briefly introduces the Hilbert SFC renumbering technique and illustrates its use with two different approaches to parallelization: an out-of-core method and a shared-memory multi-threaded algorithm.
