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.

SYNOPSIS

       C or C++:
       #include <mpp/shmem.h>

       void shmem_barrier_all(void);

       Fortran:
       include 'mpp/shmem.h'

       CALL SHMEM_BARRIER_ALL

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.

       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 shmem_put32(3).

EXAMPLES

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

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