SHMEM_FINALIZE(3)                  Open MPI                  SHMEM_FINALIZE(3)


shmem_finalize - A collective operation that releases resources used by the
OpenSHMEM library. This only terminates the Open-SHMEM portion of a program,
not the entire program.

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.
