File: mld_d_onelev_mod.f90 ! ! Module: mld_d_onelev_mod ! ! This module defines: ! - the mld_d_onelev_type data structure containing one level ! of a multilevel preconditioner and related ! data structures; ! ! It contains routines for ! - Building and applying; ! - checking if the preconditioner is correctly defined; ! - printing a description of the preconditioner; ! - deallocating the preconditioner data structure. ! module mld_d_onelev_mod use mld_base_prec_type use mld_d_base_smoother_mod use psb_base_mod, only : psb_dspmat_type, psb_d_vect_type, & & psb_d_base_vect_type, psb_dlinmap_type, psb_dpk_, & & psb_ipk_, psb_long_int_k_, psb_desc_type, psb_i_base_vect_type, & & psb_erractionsave, psb_error_handler ! ! ! Type: mld_Tonelev_type. ! ! It is the data type containing the necessary items for the current ! level (essentially, the smoother, the current-level matrix ! and the restriction and prolongation operators). ! ! type mld_Tonelev_type ! class(mld_T_base_smoother_type), allocatable :: sm ! type(mld_RTml_parms) :: parms ! type(psb_Tspmat_type) :: ac ! type(psb_Tesc_type) :: desc_ac ! type(psb_Tspmat_type), pointer :: base_a => null() ! type(psb_Tesc_type), pointer :: base_desc => null() ! type(psb_Tlinmap_type) :: map ! end type mld_Tonelev_type ! ! Note that psb_Tpk denotes the kind of the real data type to be chosen ! according to single/double precision version of MLD2P4. ! ! sm - class(mld_T_base_smoother_type), allocatable ! The current level preconditioner (aka smoother). ! parms - type(mld_RTml_parms) ! The parameters defining the multilevel strategy. ! ac - The local part of the current-level matrix, built by ! coarsening the previous-level matrix. ! desc_ac - type(psb_desc_type). ! The communication descriptor associated to the matrix ! stored in ac. ! base_a - type(psb_Tspmat_type), pointer. ! Pointer (really a pointer!) to the local part of the current ! matrix (so we have a unified treatment of residuals). ! We need this to avoid passing explicitly the current matrix ! to the routine which applies the preconditioner. ! base_desc - type(psb_desc_type), pointer. ! Pointer to the communication descriptor associated to the ! matrix pointed by base_a. ! map - Stores the maps (restriction and prolongation) between the ! vector spaces associated to the index spaces of the previous ! and current levels. ! ! Methods: ! Most methods follow the encapsulation hierarchy: they take whatever action ! is appropriate for the current object, then call the corresponding method for ! the contained object. ! As an example: the descr() method prints out a description of the ! level. It starts by invoking the descr() method of the parms object, ! then calls the descr() method of the smoother object. ! ! descr - Prints a description of the object. ! default - Set default values ! dump - Dump to file object contents ! set - Sets various parameters; when a request is unknown ! it is passed to the smoother object for further processing. ! check - Sanity checks. ! sizeof - Total memory occupation in bytes ! get_nzeros - Number of nonzeros ! get_wrksz - How many workspace vector does apply_vect need ! ! type mld_dmlprec_wrk_type real(psb_dpk_), allocatable :: tx(:), ty(:), x2l(:), y2l(:) type(psb_d_vect_type) :: vtx, vty, vx2l, vy2l integer(psb_ipk_) :: wvsz = 0 type(psb_d_vect_type), allocatable :: wv(:) contains procedure, pass(wk) :: alloc => d_wrk_alloc procedure, pass(wk) :: free => d_wrk_free procedure, pass(wk) :: clone => d_wrk_clone procedure, pass(wk) :: move_alloc => d_wrk_move_alloc end type mld_dmlprec_wrk_type private :: d_wrk_alloc, d_wrk_free, & & d_wrk_clone, d_wrk_move_alloc type mld_d_onelev_type class(mld_d_base_smoother_type), allocatable :: sm, sm2a class(mld_d_base_smoother_type), pointer :: sm2 => null() class(mld_dmlprec_wrk_type), allocatable :: wrk type(mld_dml_parms) :: parms type(psb_dspmat_type) :: ac integer(psb_ipk_) :: ac_nz_loc, ac_nz_tot type(psb_desc_type) :: desc_ac type(psb_dspmat_type), pointer :: base_a => null() type(psb_desc_type), pointer :: base_desc => null() type(psb_dspmat_type) :: tprol type(psb_dlinmap_type) :: map real(psb_dpk_) :: szratio contains procedure, pass(lv) :: bld => mld_d_base_onelev_build procedure, pass(lv) :: clone => d_base_onelev_clone procedure, pass(lv) :: cnv => mld_d_base_onelev_cnv procedure, pass(lv) :: descr => mld_d_base_onelev_descr procedure, pass(lv) :: default => d_base_onelev_default procedure, pass(lv) :: free => mld_d_base_onelev_free procedure, pass(lv) :: nullify => d_base_onelev_nullify procedure, pass(lv) :: check => mld_d_base_onelev_check procedure, pass(lv) :: dump => mld_d_base_onelev_dump procedure, pass(lv) :: seti => mld_d_base_onelev_seti procedure, pass(lv) :: setr => mld_d_base_onelev_setr procedure, pass(lv) :: setc => mld_d_base_onelev_setc procedure, pass(lv) :: cseti => mld_d_base_onelev_cseti procedure, pass(lv) :: csetr => mld_d_base_onelev_csetr procedure, pass(lv) :: csetc => mld_d_base_onelev_csetc procedure, pass(lv) :: setsm => mld_d_base_onelev_setsm procedure, pass(lv) :: setsv => mld_d_base_onelev_setsv generic, public :: set => seti, setr, setc, & & cseti, csetr, csetc, setsm, setsv procedure, pass(lv) :: sizeof => d_base_onelev_sizeof procedure, pass(lv) :: get_nzeros => d_base_onelev_get_nzeros procedure, pass(lv) :: get_wrksz => d_base_onelev_get_wrksize procedure, pass(lv) :: allocate_wrk => d_base_onelev_allocate_wrk procedure, pass(lv) :: free_wrk => d_base_onelev_free_wrk procedure, nopass :: stringval => mld_stringval procedure, pass(lv) :: move_alloc => d_base_onelev_move_alloc end type mld_d_onelev_type type mld_d_onelev_node type(mld_d_onelev_type) :: item type(mld_d_onelev_node), pointer :: prev=>null(), next=>null() end type mld_d_onelev_node private :: d_base_onelev_default, d_base_onelev_sizeof, & & d_base_onelev_nullify, d_base_onelev_get_nzeros, & & d_base_onelev_clone, d_base_onelev_move_alloc, & & d_base_onelev_get_wrksize, d_base_onelev_allocate_wrk, & & d_base_onelev_free_wrk interface subroutine mld_d_base_onelev_build(lv,info,amold,vmold,imold) import :: psb_d_base_sparse_mat, psb_d_base_vect_type, & & psb_i_base_vect_type, psb_dpk_, mld_d_onelev_type, & & psb_ipk_, psb_long_int_k_, psb_desc_type implicit none class(mld_d_onelev_type), target, intent(inout) :: lv integer(psb_ipk_), intent(out) :: info class(psb_d_base_sparse_mat), intent(in), optional :: amold class(psb_d_base_vect_type), intent(in), optional :: vmold class(psb_i_base_vect_type), intent(in), optional :: imold end subroutine mld_d_base_onelev_build end interface interface subroutine mld_d_base_onelev_descr(lv,il,nl,ilmin,info,iout) import :: psb_dspmat_type, psb_d_vect_type, psb_d_base_vect_type, & & psb_dlinmap_type, psb_dpk_, mld_d_onelev_type, & & psb_ipk_, psb_long_int_k_, psb_desc_type Implicit None !
