SYNOPSIS

C or C++:

#include <mpp/shmem.h>
void shmem_finalize(void);

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.
