From Master Foilset for CPS615 Introduction -- Material from Culler and Koelbel Computational Science for Simulations -- Fall Semester 1998. by Geoffrey C. Fox, Nancy McCracken


In horizontal
  • Clump so that 4 points per task
  • Efficiency: communicate with 4 neighbors only
In vertical, clump all points in column
  • Performance: avoid communication
  • Modularity: Reuse physics modules
Resulting algorithm "reasonably scalable"
  • (Nx.Ny)/4 : at least 1250 tasks
