SHMEM_GLOBAL_EXIT(3) Open MPI SHMEM_GLOBAL_EXIT(3)
NAME
shmem_global_exit - A routine that allows any PE to force termination
of an entire program.
SYNOPSIS
C or C++:
#include <mpp/shmem.h>
void shmem_global_exit(int status);
Fortran:
include 'mpp/shmem.fh'
INTEGER STATUS
CALL SHMEM_GLOBAL_EXIT(status)
DESCRIPTION
shmem_global_exit() shmem_global_exit is a non-collective routine that
allows any one PE to force termination of an Open- SHMEM program for
all PEs, passing an exit status to the execution environment. This rou-
tine terminates the entire program, not just the OpenSHMEM portion.
When any PE calls shmem_global_exit, it results in the immediate noti-
fication to all PEs to terminate. shmem_global_exit flushes I/O and re-
leases resources in accordance with C/C++/Fortran language requirements
for normal program termination. If more than one PE calls
shmem_global_exit, then the exit status returned to the environment
shall be one of the values passed to shmem_global_exit as the status
argument. There is no return to the caller of shmem_global_exit; con-
trol is returned from the OpenSHMEM program to the execution environ-
ment for all PEs.
