.SH NAME
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.
.SH SYNOPSIS
C or C++:
.Vb
#include <mpp/shmem.h>
void shmem_finalize(void);
.Ve
Fortran:
.Vb
include 'mpp/shmem.fh'
CALL SHMEM_FINALIZE
.Ve
.SH 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.
