! Module: amg_d_poly_smoother_mod
!
! This module defines:
! the amg_d_poly_smoother_type data structure containing the
! smoother for a Jacobi/block Jacobi smoother.
! The smoother stores in ND the block off-diagonal matrix.
! One special case is treated separately, when the solver is DIAG or L1-DIAG
! then the ND is the entire off-diagonal part of the matrix (including the
! main diagonal block), so that it becomes possible to implement
! a pure Jacobi or L1-Jacobi global solver.

! Module: amg_d_poly_smoother_mod
!
! This module defines:
! the amg_d_poly_smoother_type data structure containing the
! smoother for a Jacobi/block Jacobi smoother.
! The smoother stores in ND the block off-diagonal matrix.
! One special case is treated separately, when the solver is DIAG or L1-DIAG
! then the ND is the entire off-diagonal part of the matrix (including the
! main diagonal block), so that it becomes possible to implement
! a pure Jacobi or L1-Jacobi global solver.
