!
|
||||
! Subroutine: mld_caggrmat_biz_bld
|
||||
! 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.
|
||||
!
|
||||
! This routine builds A_C according to a "bizarre" aggregation algorithm,
|
||||
! using a "naive" prolongator proposed by the authors of MLD2P4. However, this
|
||||
! prolongator still requires additional analysis and testing and its use is not
|
||||
! recommended.
|
||||
!
|
||||
! The coarse-level matrix A_C is distributed among the parallel processes or
|
||||
! replicated on each of them, according to the value of p%parms%coarse_mat,
|
||||
! 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_bld.
|
||||
!
|
||||
! Arguments:
|
||||
! a - type(psb_cspmat_type), input.
|
||||
! The sparse matrix structure containing the local part of
|
||||
! the fine-level matrix.
|
||||
! desc_a - type(psb_desc_type), input.
|
||||
! The communication descriptor of the fine-level matrix.
|
||||
! p - type(mld_c_onelev_type), input/output.
|
||||
! The 'one-level' data structure that will contain the local
|
||||
! part of the matrix to be built as well as the information
|
||||
! concerning the prolongator and its transpose.
|
||||
! ilaggr - integer, dimension(:), allocatable.
|
||||
! 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.
|
||||
! nlaggr - integer, dimension(:), allocatable.
|
||||
! nlaggr(i) contains the aggregates held by process i.
|
||||
! info - integer, output.
|
||||
! Error code.

|

! Subroutine: mld_daggrmat_biz_bld
|
||||
! 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.
|
||||
!
|
||||
! This routine builds A_C according to a "bizarre" aggregation algorithm,
|
||||
! using a "naive" prolongator proposed by the authors of MLD2P4. However, this
|
||||
! prolongator still requires additional analysis and testing and its use is not
|
||||
! recommended.
|
||||
!
|
||||
! The coarse-level matrix A_C is distributed among the parallel processes or
|
||||
! replicated on each of them, according to the value of p%parms%coarse_mat,
|
||||
! 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_bld.
|
||||
!
|
||||
! Arguments:
|
||||
! a - type(psb_dspmat_type), input.
|
||||
! The sparse matrix structure containing the local part of
|
||||
! the fine-level matrix.
|
||||
! desc_a - type(psb_desc_type), input.
|
||||
! The communication descriptor of the fine-level matrix.
|
||||
! p - type(mld_d_onelev_type), input/output.
|
||||
! The 'one-level' data structure that will contain the local
|
||||
! part of the matrix to be built as well as the information
|
||||
! concerning the prolongator and its transpose.
|
||||
! ilaggr - integer, dimension(:), allocatable.
|
||||
! 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.
|
||||
! nlaggr - integer, dimension(:), allocatable.
|
||||
! nlaggr(i) contains the aggregates held by process i.
|
||||
! info - integer, output.

!
|

! Subroutine: mld_saggrmat_biz_bld
|
||||
! 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.
|
||||
!
|
||||
! This routine builds A_C according to a "bizarre" aggregation algorithm,
|
||||
! using a "naive" prolongator proposed by the authors of MLD2P4. However, this
|
||||
! prolongator still requires additional analysis and testing and its use is not
|
||||
! recommended.
|
||||
!
|
||||
! The coarse-level matrix A_C is distributed among the parallel processes or
|
||||
! replicated on each of them, according to the value of p%parms%coarse_mat,
|
||||
! 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_bld.
|
||||
!
|
||||
! Arguments:
|
||||
! a - type(psb_sspmat_type), input.
|
||||
! The sparse matrix structure containing the local part of
|
||||
! the fine-level matrix.
|
||||
! desc_a - type(psb_desc_type), input.
|
||||
! The communication descriptor of the fine-level matrix.
|
||||
! p - type(mld_s_onelev_type), input/output.
|
||||
! The 'one-level' data structure that will contain the local
|
||||
! part of the matrix to be built as well as the information
|
||||
! concerning the prolongator and its transpose.
|
||||
! ilaggr - integer, dimension(:), allocatable.
|
||||
! 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.
|
||||
! nlaggr - integer, dimension(:), allocatable.
|
||||
! nlaggr(i) contains the aggregates held by process i.
|
||||
! info - integer, output.

! Error code.

!
|
||||
! Subroutine: mld_zaggrmat_biz_bld
|
||||
! 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.
|
||||
!
|
||||
! This routine builds A_C according to a "bizarre" aggregation algorithm,
|
||||
! using a "naive" prolongator proposed by the authors of MLD2P4. However, this
|
||||
! prolongator still requires additional analysis and testing and its use is not
|
||||
! recommended.
|
||||
!
|
||||
! The coarse-level matrix A_C is distributed among the parallel processes or
|
||||
! replicated on each of them, according to the value of p%parms%coarse_mat,
|
||||
! 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_bld.
|
||||
!
|
||||
! Arguments:
|
||||
! a - type(psb_zspmat_type), input.
|
||||
! The sparse matrix structure containing the local part of
|
||||
! the fine-level matrix.
|
||||
! desc_a - type(psb_desc_type), input.
|
||||
! The communication descriptor of the fine-level matrix.
|
||||
! p - type(mld_z_onelev_type), input/output.
|
||||
! The 'one-level' data structure that will contain the local
|
||||
! part of the matrix to be built as well as the information
|
||||
! concerning the prolongator and its transpose.
|
||||
! ilaggr - integer, dimension(:), allocatable.
|
||||
! 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.
|
||||
! nlaggr - integer, dimension(:), allocatable.
|
||||
! nlaggr(i) contains the aggregates held by process i.
|
||||
! info - integer, output.
|
||||
! Error code.
