.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.
