!
|

! Subroutine: mld_z_lev_aggrmap_bld
|
||||
! Version: complex
|
||||
!
|
||||
! This routine is just an interface to aggrmap_bld where the real work is performed.
|
||||
! It takes care of some consistency checking though.
|
||||
!
|
||||
! See mld_zaggrmap_bld for constraints on input/oput arguments.
|
||||
!
|
||||
!
|
||||
! 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(:), allocatable, output
|
||||
! 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 on exit the indices
|
||||
! will be shifted so as to make sure the ranges on the various processes do not
|
||||
! overlap.
|
||||
! nlaggr - integer, dimension(:), allocatable, output
|
||||
! nlaggr(i) contains the aggregates held by process i.
|
||||
! op_prol - type(psb_zspmat_type), output
|
||||
! The tentative prolongator, based on ilaggr.
|
||||
!
|
||||
! info - integer, output.
|
||||
! Error code.
