DESCRIPTION

       The routines return after posting the operation.  The  operation  is  considered  complete
       after  a  subsequent  call  to shmem_quiet. At the completion of shmem_quiet, the data has
       been copied into the dest array on the destination PE.  The delivery of  data  words  into
       the  data object on the destination PE may occur in any order. Furthermore, two successive
       put routines may deliver data out of order unless a  call  to  shmem_fence  is  introduced
       between the two calls.

       The arguments are as follows:

       dest   Data  object  to  be  updated  on  the remote PE. This data object must be remotely
              accessible.

       source Data object containing the data to be copied.

       nelems Number of elements in the dest and source arrays. nelems must be of type size_t for
              C.  If  you are using Fortran, it must be a constant, variable, or array element of
              default integer type.

       pe     PE number of the remote PE. pe must be of type integer. If you are  using  Fortran,
              it must be a constant, variable, or array element of default integer type.

       If you are using Fortran, data types must be of default size. For example, a real variable
       must be declared as REAL, REAL*4, or REAL(KIND=4).

NOTES

       See intro_shmem(3) for a definition of the term remotely accessible.

EXAMPLES

       Consider this simple example for C.
       #include <stdio.h>
       #include <mpp/shmem.h>

       main()
       {
         long source[10] = { 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 };
         static long target[10];
         shmem_init();

         if (shmem_my_pe() == 0) {
           /* put 10 words into target on PE 1 */
           shmem_long_put_nbi(target, source, 10, 1);
           shmem_quiet();
         }
         shmem_barrier_all();  /* sync sender and receiver */
         if (shmem_my_pe() == 1)
           shmem_udcflush();  /* not required on Altix systems */
         printf("target[0] on PE %d is %d\n", shmem_my_pe(), target[0]);
       }
