module mld_z_dec_aggregator_mod

use mld_z_base_aggregator_mod
|
||||
!
|
||||
! 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
