Foil 37 Memory Use in Direct and Iterative Methods

From CPS615 Module on Iterative PDE Solvers CPS615 Basic Simulation Track for Computational Science -- Fall Semester 95. by Geoffrey C. Fox


1 One Dimension: Both Sparse and Direct Methods use memory of order G -- the matrix size
2 In two dimensions,
  • Direct Method: Space is of order G3
  • Sparse Method: Space is of order G2
3 In three dimensions,
  • Direct Method: Space is of order G5
  • Sparse Method: Space is of order G3
