! there will be few processes, compared to indices, so it is possible
! to answer the ownership question without resorting to data exchange
! (well, the data exchange is needed but only once at initial allocation
! time).
! time). These are stored in VNL in a format similar to the pointers
! in CSR.
!
! The halo indices may be stored in three different places:
! 1. map%loc_to_glob(:)
! This stores the global indices corresponding to local halo
! indices, not the owned indices that can be determined from
! min_glob_row and max_glob_row; hence any access into this
! vector has to be rescaled by N_ROW.
! 2. map%srt_g2l(:,:)
! This contains in column 1 the same global indices as in loc_to_glob
! sorted for quick access, and in column 2 the corresponding local
! index; it is set up at assembly time.
! 3. map%hash
! This is used when the map is in the bld state, so that g2l queries can
! be answered quickly before the availability of srt_g2l.
