SHMEM_FINALIZE(3) Open MPI SHMEM_FINALIZE(3)
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 por-
tion of a program previously initialized by shmem_init and releases re-
sources used by the OpenSHMEM library. This collective operation re-
quires 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_fi-
nalize. shmem_finalize must be the last OpenSHMEM library call encoun-
tered 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.
