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.
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.
