File: amg_s_onelev_mod.f90 ! ! Module: amg_s_onelev_mod ! ! This module defines: ! - the amg_s_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 amg_s_onelev_mod use amg_base_prec_type use amg_s_base_smoother_mod use amg_s_dec_aggregator_mod use psb_base_mod, only : psb_sspmat_type, psb_s_vect_type, & & psb_s_base_vect_type, psb_lsspmat_type, psb_slinmap_type, psb_spk_, & & psb_ipk_, psb_epk_, psb_lpk_, psb_desc_type, psb_i_base_vect_type, & & psb_erractionsave, psb_error_handler ! ! !

Note that s denotes the kind of the real data type to be chosen ! according to single/double precision version of MLD2P4. ! ! sm,sm2a - class(amg_s_base_smoother_type), allocatable ! The current level pre- and post-smooother. ! sm2 - class(amg_s_base_smoother_type), pointer ! The current level post-smooother; if sm2a is allocated ! explicitly, then sm2 => sm2a, otherwise sm2 => sm. ! wrk - class(amg_smlprec_wrk_type), allocatable ! Workspace for application of preconditioner; may be ! pre-allocated to save time in the application within a ! Krylov solver. ! aggr - class(amg_s_base_aggregator_type), allocatable ! The aggregator object: holds the algorithmic choices and ! (possibly) additional data for building the aggregation. ! parms - type(amg_sml_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_sspmat_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 ! allocate_wrk - Allocate auxiliary workspace ! free_wrk - Free auxiliary workspace ! bld_tprol - Invoke the aggr method to build the tentative prolongator ! mat_asb - Build the final (possibly smoothed) prolongator and coarse matrix. ! ! type amg_smlprec_wrk_type real(psb_spk_), allocatable :: tx(:), ty(:), x2l(:), y2l(:) type(psb_s_vect_type) :: vtx, vty, vx2l, vy2l type(psb_s_vect_type), allocatable :: wv(:) contains procedure, pass(wk) :: alloc => s_wrk_alloc procedure, pass(wk) :: free => s_wrk_free procedure, pass(wk) :: clone => s_wrk_clone procedure, pass(wk) :: move_alloc => s_wrk_move_alloc procedure, pass(wk) :: cnv => s_wrk_cnv procedure, pass(wk) :: sizeof => s_wrk_sizeof end type amg_smlprec_wrk_type private :: s_wrk_alloc, s_wrk_free, & & s_wrk_clone, s_wrk_move_alloc, s_wrk_cnv, s_wrk_sizeof type amg_s_onelev_type class(amg_s_base_smoother_type), allocatable :: sm, sm2a class(amg_s_base_smoother_type), pointer :: sm2 => null() class(amg_smlprec_wrk_type), allocatable :: wrk class(amg_s_base_aggregator_type), allocatable :: aggr type(amg_sml_parms) :: parms type(psb_sspmat_type) :: ac integer(psb_ipk_) :: ac_nz_loc integer(psb_lpk_) :: ac_nz_tot type(psb_desc_type) :: desc_ac type(psb_sspmat_type), pointer :: base_a => null() type(psb_desc_type), pointer :: base_desc => null() type(psb_lsspmat_type) :: tprol type(psb_slinmap_type) :: map real(psb_spk_) :: szratio contains procedure, pass(lv) :: bld_tprol => s_base_onelev_bld_tprol procedure, pass(lv) :: mat_asb => amg_s_base_onelev_mat_asb procedure, pass(lv) :: update_aggr => s_base_onelev_update_aggr procedure, pass(lv) :: bld => amg_s_base_onelev_build procedure, pass(lv) :: clone => s_base_onelev_clone procedure, pass(lv) :: cnv => amg_s_base_onelev_cnv procedure, pass(lv) :: descr => amg_s_base_onelev_descr procedure, pass(lv) :: default => s_base_onelev_default procedure, pass(lv) :: free => amg_s_base_onelev_free procedure, pass(lv) :: nullify => s_base_onelev_nullify procedure, pass(lv) :: check => amg_s_base_onelev_check procedure, pass(lv) :: dump => amg_s_base_onelev_dump procedure, pass(lv) :: cseti => amg_s_base_onelev_cseti procedure, pass(lv) :: csetr => amg_s_base_onelev_csetr procedure, pass(lv) :: csetc => amg_s_base_onelev_csetc procedure, pass(lv) :: setsm => amg_s_base_onelev_setsm procedure, pass(lv) :: setsv => amg_s_base_onelev_setsv procedure, pass(lv) :: setag => amg_s_base_onelev_setag generic, public :: set => cseti, csetr, csetc, setsm, setsv, setag procedure, pass(lv) :: sizeof => s_base_onelev_sizeof procedure, pass(lv) :: get_nzeros => s_base_onelev_get_nzeros procedure, pass(lv) :: get_wrksz => s_base_onelev_get_wrksize procedure, pass(lv) :: allocate_wrk => s_base_onelev_allocate_wrk procedure, pass(lv) :: free_wrk => s_base_onelev_free_wrk procedure, nopass :: stringval => amg_stringval procedure, pass(lv) :: move_alloc => s_base_onelev_move_alloc end type amg_s_onelev_type type amg_s_onelev_node type(amg_s_onelev_type) :: item type(amg_s_onelev_node), pointer :: prev=>null(), next=>null() end type amg_s_onelev_node private :: s_base_onelev_default, s_base_onelev_sizeof, & & s_base_onelev_nullify, s_base_onelev_get_nzeros, & & s_base_onelev_clone, s_base_onelev_move_alloc, & & s_base_onelev_get_wrksize, s_base_onelev_allocate_wrk, & & s_base_onelev_free_wrk interface subroutine amg_s_base_onelev_mat_asb(lv,a,desc_a,ilaggr,nlaggr,t_prol,info) import :: psb_sspmat_type, psb_desc_type, psb_spk_, psb_ipk_, psb_lsspmat_type, psb_lpk_ import :: amg_s_onelev_type implicit none class(amg_s_onelev_type), intent(inout), target :: lv type(psb_sspmat_type), intent(in) :: a type(psb_desc_type), intent(inout) :: desc_a integer(psb_lpk_), intent(inout) :: ilaggr(:),nlaggr(:) type(psb_lsspmat_type), intent(inout) :: t_prol integer(psb_ipk_), intent(out) :: info end subroutine amg_s_base_onelev_mat_asb end interface interface subroutine amg_s_base_onelev_build(lv,info,amold,vmold,imold,ilv) import :: psb_s_base_sparse_mat, psb_s_base_vect_type, & & psb_i_base_vect_type, psb_spk_, amg_s_onelev_type, & & psb_ipk_, psb_epk_, psb_desc_type implicit none class(amg_s_onelev_type), target, intent(inout) :: lv integer(psb_ipk_), intent(out) :: info class(psb_s_base_sparse_mat), intent(in), optional :: amold class(psb_s_base_vect_type), intent(in), optional :: vmold class(psb_i_base_vect_type), intent(in), optional :: imold integer(psb_ipk_), intent(in), optional :: ilv end subroutine amg_s_base_onelev_build end interface interface subroutine amg_s_base_onelev_descr(lv,il,nl,ilmin,info,iout) import :: psb_sspmat_type, psb_s_vect_type, psb_s_base_vect_type, & & psb_slinmap_type, psb_spk_, amg_s_onelev_type, & & psb_ipk_, psb_epk_, psb_desc_type Implicit None !
