ZPL Assumes Many Pts/Proc

ZPL allocates arrays to processors so that many contiguous elements are assigned to each processor

• The array allocation rules:

  • Union the regions, compute bounding region
  • Accept processor number and arrangement from command line
  • 1D and 2D processor grids are (presently) available
  • Allocate the bounding region, inducing array allocation

• nPt/Proc is just as natural as 1Pt/Proc
