Description

  • Use norm of right-hand side instead of initial error for scaling residuals in iterative solvers. This yields consistent results when starting with a decent initial approximation.
  • Provide an HPX backend.
  • Accept near null-space vectors for aggregation-based coarsening.
  • Added SPAI(1) smoother (may work better than SPAI(0), but is extremely slow to setup for larger problems).
  • Iterative solvers now provide apply() methods, so that they may be used as preconditioners themselves.
  • Various fixes and improvements.
