Telluride Solver Options

• Originally:
  • CG, GMRES
  • Jacobi, SSOR
• Later added preconditioning via orthogonal operator
  • 7-pt. stencil, simply-connected
  • orthogonal system solved by CG
  • Jacobi, SSOR preconditioning
  • still a global solve in preconditioner
• Additive Schwarz
  • precondition on subdomains only
  • no overlap
  • for orthogonal operator, increases options for subdomain solves
    • SSOR
    • Incomplete factorizations
    • Multigrid
  • surprisingly minor modifications to Telluride required
