\fI\%shmem_barrier_all\fP \- Suspends the execution of the calling PE until all
other PEs issue a call to this particular shmem_barrier_all() statement.

.SH DESCRIPTION
.sp
The \fI\%shmem_barrier_all\fP routine does not return until all other PEs have
entered this routine at the same point of the execution path.
.sp
Prior to synchronizing with other PEs, \fI\%shmem_barrier_all\fP ensures
completion of all previously issued local memory stores and remote
memory updates issued via SHMEM functions such as \fI\%shmem_put32\fP(3).

setup_data()
{
  if (shmem_my_pe() == 0) {
    setup();
  }

  /* All PEs wait for PE 0 to complete setup().  */
  shmem_barrier_all();
}
