!
|
||||
! Subroutine: mld_c_lev_aggrmat_asb
|
||||
! Version: complex
|
||||
!
|
||||
! This routine builds the matrix associated to the current level of the
|
||||
! multilevel preconditioner from the matrix associated to the previous level,
|
||||
! by using the user-specified aggregation technique (therefore, it also builds the
|
||||
! prolongation and restriction operators mapping the current level to the
|
||||
! previous one and vice versa).
|
||||
! The current level is regarded as the coarse one, while the previous as
|
||||
! the fine one. This is in agreement with the fact that the routine is called,
|
||||
! by mld_mlprec_bld, only on levels >=2.
|
||||
! The main structure is:
|
||||
! 1. Perform sanity checks;
|
||||
! 2. Call mld_Xaggrmat_asb to compute prolongator/restrictor/AC
|
||||
! 3. According to the choice of DIST/REPL for AC, build a descriptor DESC_AC,
|
||||
! and adjust the column numbering of AC/OP_PROL/OP_RESTR
|
||||
! 4. Pack restrictor and prolongator into p%map
|
||||
! 5. Fix base_a and base_desc pointers.
|
||||
!
|
||||
!
|
||||
! Arguments:
|
||||
! p - type(mld_c_onelev_type), input/output.
|
||||
! The 'one-level' data structure containing the control
|
||||
! parameters and (eventually) coarse matrix and prolongator/restrictors.
|
||||
!
|
||||
! a - type(psb_cspmat_type).
|
||||
! The sparse matrix structure containing the local part of the
|
||||
! fine-level matrix.
|
||||
! desc_a - type(psb_desc_type), input.
|
||||
! The communication descriptor of a.
|
||||
! ilaggr - integer, dimension(:), input
|
||||
! The mapping between the row indices of the coarse-level
|
||||
! matrix and the row indices of the fine-level matrix.
|
||||
! ilaggr(i)=j means that node i in the adjacency graph
|
||||
! of the fine-level matrix is mapped onto node j in the
|
||||
! adjacency graph of the coarse-level matrix. Note that the indices
|
||||
! are assumed to be shifted so as to make sure the ranges on
|
||||
! the various processes do not overlap.
|
||||
! nlaggr - integer, dimension(:) input
|
||||
! nlaggr(i) contains the aggregates held by process i.
|
||||
! op_prol - type(psb_cspmat_type), input/output
|
||||
! The tentative prolongator on input, released on output.
|
||||
!
|
||||
! info - integer, output.

! Subroutine: mld_caggrmat_asb
|
||||
! Version: complex
|
||||
!
|
||||
! This routine builds a coarse-level matrix A_C from a fine-level matrix A
|
||||
! by using the Galerkin approach, i.e.
|
||||
!
|
||||
! A_C = P_C^T A P_C,
|
||||
!
|
||||
! where P_C is a prolongator from the coarse level to the fine one.
|
||||
!
|
||||
! A mapping from the nodes of the adjacency graph of A to the nodes of the
|
||||
! adjacency graph of A_C has been computed by the mld_aggrmap_bld subroutine.
|
||||
! The prolongator P_C is built here from this mapping, according to the
|
||||
! value of p%iprcparm(mld_aggr_prol_), specified by the user through
|
||||
! mld_cprecinit and mld_zprecset.
|
||||
! On output from this routine the entries of AC, op_prol, op_restr
|
||||
! are still in "global numbering" mode; this is fixed in the calling routine
|
||||
! mld_c_lev_aggrmat_asb.
|
||||
!
|
||||
! Currently four different prolongators are implemented, corresponding to
|
||||
! four aggregation algorithms:
|
||||
! 1. un-smoothed aggregation,
|
||||
! 2. smoothed aggregation,
|
||||
! 3. "bizarre" aggregation.
|
||||
! 4. minimum energy
|
||||
! 1. The non-smoothed aggregation uses as prolongator the piecewise constant
|
||||
! interpolation operator corresponding to the fine-to-coarse level mapping built
|
||||
! by mld_aggrmap_bld. This is called tentative prolongator.
|
||||
! 2. The smoothed aggregation uses as prolongator the operator obtained by applying
|
||||
! a damped Jacobi smoother to the tentative prolongator.
|
||||
! 3. The "bizarre" aggregation uses a prolongator proposed by the authors of MLD2P4.

|
||||
! Version: real
|
||||
!
|
||||
! This routine builds the matrix associated to the current level of the
|
||||
! multilevel preconditioner from the matrix associated to the previous level,
|
||||
! by using the user-specified aggregation technique (therefore, it also builds the
|
||||
! prolongation and restriction operators mapping the current level to the
|
||||
! previous one and vice versa).
|
||||
! The current level is regarded as the coarse one, while the previous as
|
||||
! the fine one. This is in agreement with the fact that the routine is called,
|
||||
! by mld_mlprec_bld, only on levels >=2.
|
||||
! The main structure is:
|
||||
! 1. Perform sanity checks;
|
||||
! 2. Call mld_Xaggrmat_asb to compute prolongator/restrictor/AC
|
||||
! 3. According to the choice of DIST/REPL for AC, build a descriptor DESC_AC,
|
||||
! and adjust the column numbering of AC/OP_PROL/OP_RESTR
|
||||
! 4. Pack restrictor and prolongator into p%map
|
||||
! 5. Fix base_a and base_desc pointers.
|
||||
!
|
||||
!
|
||||
! Arguments:

! p - type(mld_d_onelev_type), input/output.

|

! Subroutine: mld_daggrmat_asb
|
||||
! Version: real
|
||||
!
|
||||
! This routine builds a coarse-level matrix A_C from a fine-level matrix A
|
||||
! by using the Galerkin approach, i.e.
|
||||
!
|
||||
! A_C = P_C^T A P_C,
|
||||
!
|
||||
! where P_C is a prolongator from the coarse level to the fine one.
|
||||
!
|
||||
! A mapping from the nodes of the adjacency graph of A to the nodes of the
|
||||
! adjacency graph of A_C has been computed by the mld_aggrmap_bld subroutine.
|
||||
! The prolongator P_C is built here from this mapping, according to the
|
||||
! value of p%iprcparm(mld_aggr_prol_), specified by the user through
|
||||
! mld_dprecinit and mld_zprecset.
|
||||
! On output from this routine the entries of AC, op_prol, op_restr
|
||||
! are still in "global numbering" mode; this is fixed in the calling routine
|
||||
! mld_d_lev_aggrmat_asb.
|
||||
!
|
||||
! Currently four different prolongators are implemented, corresponding to
|
||||
! four aggregation algorithms:
|
||||
! 1. un-smoothed aggregation,
|
||||
! 2. smoothed aggregation,
|
||||
! 3. "bizarre" aggregation.
|
||||
! 4. minimum energy
|
||||
! 1. The non-smoothed aggregation uses as prolongator the piecewise constant
|
||||
! interpolation operator corresponding to the fine-to-coarse level mapping built
|
||||
! by mld_aggrmap_bld. This is called tentative prolongator.
|
||||
! 2. The smoothed aggregation uses as prolongator the operator obtained by applying
|
||||
! a damped Jacobi smoother to the tentative prolongator.
|
||||
! 3. The "bizarre" aggregation uses a prolongator proposed by the authors of MLD2P4.
|
||||
! This prolongator still requires a deep analysis and testing and its use is
|
||||
! not recommended.
|
||||
! 4. Minimum energy aggregation: ADD REFERENCE.

! Subroutine: mld_s_lev_aggrmat_asb
|
||||
! Version: real
|
||||
!
|
||||
! This routine builds the matrix associated to the current level of the
|
||||
! multilevel preconditioner from the matrix associated to the previous level,
|
||||
! by using the user-specified aggregation technique (therefore, it also builds the
|
||||
! prolongation and restriction operators mapping the current level to the
|
||||
! previous one and vice versa).
|
||||
! The current level is regarded as the coarse one, while the previous as
|
||||
! the fine one. This is in agreement with the fact that the routine is called,
|
||||
! by mld_mlprec_bld, only on levels >=2.
|
||||
! The main structure is:
|
||||
! 1. Perform sanity checks;
|
||||
! 2. Call mld_Xaggrmat_asb to compute prolongator/restrictor/AC
|
||||
! 3. According to the choice of DIST/REPL for AC, build a descriptor DESC_AC,
|
||||
! and adjust the column numbering of AC/OP_PROL/OP_RESTR
|
||||
! 4. Pack restrictor and prolongator into p%map
|
||||
! 5. Fix base_a and base_desc pointers.
|
||||
!
|
||||
!
|
||||
! Arguments:
|
||||
! p - type(mld_s_onelev_type), input/output.
|
||||
! The 'one-level' data structure containing the control
|
||||
! parameters and (eventually) coarse matrix and prolongator/restrictors.
|
||||
!
|
||||
! a - type(psb_sspmat_type).
|
||||
! The sparse matrix structure containing the local part of the
|
||||
! fine-level matrix.
|
||||
! desc_a - type(psb_desc_type), input.
|
||||
! The communication descriptor of a.
|
||||
! ilaggr - integer, dimension(:), input
|
||||
! The mapping between the row indices of the coarse-level
|
||||
! matrix and the row indices of the fine-level matrix.
|
||||
! ilaggr(i)=j means that node i in the adjacency graph
|
||||
! of the fine-level matrix is mapped onto node j in the
|
||||
! adjacency graph of the coarse-level matrix. Note that the indices
|
||||
! are assumed to be shifted so as to make sure the ranges on
|
||||
! the various processes do not overlap.
|
||||
! nlaggr - integer, dimension(:) input
|
||||
! nlaggr(i) contains the aggregates held by process i.
|
||||
! op_prol - type(psb_sspmat_type), input/output
|
||||
! The tentative prolongator on input, released on output.

|

! Subroutine: mld_saggrmat_asb
|
||||
! Version: real
|
||||
!
|
||||
! This routine builds a coarse-level matrix A_C from a fine-level matrix A
|
||||
! by using the Galerkin approach, i.e.
|
||||
!
|
||||
! A_C = P_C^T A P_C,
|
||||
!
|
||||
! where P_C is a prolongator from the coarse level to the fine one.
|
||||
!
|
||||
! A mapping from the nodes of the adjacency graph of A to the nodes of the
|
||||
! adjacency graph of A_C has been computed by the mld_aggrmap_bld subroutine.
|
||||
! The prolongator P_C is built here from this mapping, according to the
|
||||
! value of p%iprcparm(mld_aggr_prol_), specified by the user through
|
||||
! mld_sprecinit and mld_zprecset.
|
||||
! On output from this routine the entries of AC, op_prol, op_restr
|
||||
! are still in "global numbering" mode; this is fixed in the calling routine
|
||||
! mld_s_lev_aggrmat_asb.
|
||||
!
|
||||
! Currently four different prolongators are implemented, corresponding to
|
||||
! four aggregation algorithms:
|
||||
! 1. un-smoothed aggregation,
|
||||
! 2. smoothed aggregation,
|
||||
! 3. "bizarre" aggregation.
|
||||
! 4. minimum energy
|
||||
! 1. The non-smoothed aggregation uses as prolongator the piecewise constant
|
||||
! interpolation operator corresponding to the fine-to-coarse level mapping built
|
||||
! by mld_aggrmap_bld. This is called tentative prolongator.
|
||||
! 2. The smoothed aggregation uses as prolongator the operator obtained by applying
|
||||
! a damped Jacobi smoother to the tentative prolongator.
|
||||
! 3. The "bizarre" aggregation uses a prolongator proposed by the authors of MLD2P4.
|
||||
! This prolongator still requires a deep analysis and testing and its use is
|
||||
! not recommended.
|
||||
! 4. Minimum energy aggregation: ADD REFERENCE.

!
|

! Subroutine: mld_z_lev_aggrmat_asb
|
||||
! Version: complex
|
||||
!
|
||||
! This routine builds the matrix associated to the current level of the
|
||||
! multilevel preconditioner from the matrix associated to the previous level,
|
||||
! by using the user-specified aggregation technique (therefore, it also builds the
|
||||
! prolongation and restriction operators mapping the current level to the
|
||||
! previous one and vice versa).
|
||||
! The current level is regarded as the coarse one, while the previous as
|
||||
! the fine one. This is in agreement with the fact that the routine is called,
|
||||
! by mld_mlprec_bld, only on levels >=2.
|
||||
! The main structure is:
|
||||
! 1. Perform sanity checks;
|
||||
! 2. Call mld_Xaggrmat_asb to compute prolongator/restrictor/AC
|
||||
! 3. According to the choice of DIST/REPL for AC, build a descriptor DESC_AC,
|
||||
! and adjust the column numbering of AC/OP_PROL/OP_RESTR
|
||||
! 4. Pack restrictor and prolongator into p%map
|
||||
! 5. Fix base_a and base_desc pointers.
|
||||
!
|
||||
!
|
||||
! Arguments:
|
||||
! p - type(mld_z_onelev_type), input/output.
|
||||
! The 'one-level' data structure containing the control
|
||||
! parameters and (eventually) coarse matrix and prolongator/restrictors.
|
||||
!
|
||||
! a - type(psb_zspmat_type).
|
||||
! The sparse matrix structure containing the local part of the
|
||||
! fine-level matrix.
|
||||
! desc_a - type(psb_desc_type), input.
|
||||
! The communication descriptor of a.
|
||||
! ilaggr - integer, dimension(:), input
|
||||
! The mapping between the row indices of the coarse-level
|
||||
! matrix and the row indices of the fine-level matrix.
|
||||
! ilaggr(i)=j means that node i in the adjacency graph
|
||||
! of the fine-level matrix is mapped onto node j in the
|
||||
! adjacency graph of the coarse-level matrix. Note that the indices
|
||||
! are assumed to be shifted so as to make sure the ranges on
|
||||
! the various processes do not overlap.
|
||||
! nlaggr - integer, dimension(:) input
|
||||
! nlaggr(i) contains the aggregates held by process i.
|
||||
! op_prol - type(psb_zspmat_type), input/output
|
||||
! The tentative prolongator on input, released on output.
|
||||
!
|
||||
! info - integer, output.

!
|

! Subroutine: mld_zaggrmat_asb
|
||||
! Version: complex
|
||||
!
|
||||
! This routine builds a coarse-level matrix A_C from a fine-level matrix A
|
||||
! by using the Galerkin approach, i.e.
|
||||
!
|
||||
! A_C = P_C^T A P_C,
|
||||
!
|
||||
! where P_C is a prolongator from the coarse level to the fine one.
|
||||
!
|
||||
! A mapping from the nodes of the adjacency graph of A to the nodes of the
|
||||
! adjacency graph of A_C has been computed by the mld_aggrmap_bld subroutine.
|
||||
! The prolongator P_C is built here from this mapping, according to the
|
||||
! value of p%iprcparm(mld_aggr_prol_), specified by the user through
|
||||
! mld_zprecinit and mld_zprecset.
|
||||
! On output from this routine the entries of AC, op_prol, op_restr
|
||||
! are still in "global numbering" mode; this is fixed in the calling routine
|
||||
! mld_z_lev_aggrmat_asb.
|
||||
!
|
||||
! Currently four different prolongators are implemented, corresponding to
|
||||
! four aggregation algorithms:
|
||||
! 1. un-smoothed aggregation,
|
||||
! 2. smoothed aggregation,
|
||||
! 3. "bizarre" aggregation.
|
||||
! 4. minimum energy
|
||||
! 1. The non-smoothed aggregation uses as prolongator the piecewise constant
|
||||
! interpolation operator corresponding to the fine-to-coarse level mapping built
|
||||
! by mld_aggrmap_bld. This is called tentative prolongator.
|
||||
! 2. The smoothed aggregation uses as prolongator the operator obtained by applying
|
||||
! a damped Jacobi smoother to the tentative prolongator.
|
||||
! 3. The "bizarre" aggregation uses a prolongator proposed by the authors of MLD2P4.
|
||||
! This prolongator still requires a deep analysis and testing and its use is
|
||||
! not recommended.
|
||||
! 4. Minimum energy aggregation: ADD REFERENCE.
