! Subroutine: psb_loc_to_glob2
!    Performs local to global index translation. If an index is out of range
!    a negative value is returned (see also iact).

!    y(:)     - integer                   Array containing the translated indices.
!    desc_a   - type(psb_desc_type).    The communication descriptor.
