SYNOPSIS
       C or C++:

          #include <mpp/shmem.h>

          void shmem_finalize(void)

       Fortran:

          include 'mpp/shmem.fh'
          CALL SHMEM_FINALIZE


DESCRIPTION
       shmem_finalize is a collective operation  that  ends  the  OpenSHMEM  portion  of  a  program  previously
       initialized by shmem_init and releases resources used by the OpenSHMEM library. This collective operation
       requires all PEs to participate in the call. There is an implicit global  barrier  in  shmem_finalize  so
       that  pending  communication  is  completed,  and no resources can be released until all PEs have entered
       shmem_finalize.  shmem_finalize must be the last OpenSHMEM library  call  encountered  in  the  OpenSHMEM
       portion  of a program. A call to shmem_finalize will release any resources initialized by a corresponding
       call to shmem_init.  All processes and threads that represent the PEs will still exist after the call  to
       shmem_finalize returns, but they will no longer have access to any resources that have been released.
