! Subroutine: psb_loc_to_glob2
! Performs local to global indexes translation
!
! Parameters:
! x - integer, dimension(:). Array containing the indices to be translated.
! y - integer, dimension(:). Array containing the indices to be translated.
! desc_a - type(<psb_desc_type>). The communication descriptor.
! info - integer. Eventually returns an error code.
! iact - integer(optional). A character defining the behaviour of this subroutine when is found an index not belonging to the calling process
