! File: mld_zsp_renum.f90
!
! Subroutine: mld_zsp_renum
! Version: complex
! Contains: gps_reduction
!
! This routine reorders the rows and the columns of the local part of a sparse
! distributed matrix, according to one of the following criteria:
! 1. the numbering of the global column indices,
! 2. the Gibbs-Poole-Stockmeyer (GPS) band reduction algorithm.
! NOTE: the GPS algorithm is disabled for the time being (see mld_prec_type.f90).
!
! The matrix to be reordered is stored into a and blck, as specified in the
! description of the arguments below.
!
! If required by the user (p%iprcparm(mld_sub_ren_) /= 0), the routine is
! used by mld_fact_bld in building the block-Jacobi and Additive Schwarz
! 'base preconditioners' corresponding to any level of a multilevel
! preconditioner.
!
!
! Arguments:
! a - type(psb_zspmat_type), input.
! The sparse matrix structure containing the 'original' local
! part of the matrix to be reordered, i.e. the rows of the matrix
! held by the calling process according to the initial data
! distribution.
! blck - type(psb_zspmat_type), input.
! The sparse matrix structure containing the remote rows of the
! matrix to be reordered, that have been retrieved by mld_as_bld
! to build an Additive Schwarz base preconditioner with overlap
! greater than 0.If the overlap is 0, then blck does not contain
! any row.
