.TH "SHMEM\\_BARRIER\\_ALL" "3" "#OMPI_DATE#" "#PACKAGE_VERSION#" "#PACKAGE_NAME#"
.SH NAME
shmem_barrier_all \- Suspends the execution of the calling PE until all other PEs issue a call
to this particular shmem_barrier_all() statement.
.SH SYNOPSIS
C or C++:
.Vb
#include <mpp/shmem.h>
void shmem_barrier_all(void);
.Ve
Fortran:
.Vb
include 'mpp/shmem.h'
CALL SHMEM_BARRIER_ALL
.Ve
.SH DESCRIPTION
The shmem_barrier_all routine does not return until all other PEs have entered this routine
at the same point of the execution path.
.PP
Prior to synchronizing with other PEs, shmem_barrier_all ensures completion of all
previously issued local memory stores and remote memory updates issued via SHMEM
functions such as \fIshmem_put32\fP(3)\&.
.PP
.SH EXAMPLES
.Vb
setup_data()
{
if (shmem_my_pe() == 0) {
setup();
}
/* All PEs wait for PE 0 to complete setup(). */
shmem_barrier_all();
}
