DESCRIPTION

       The get routines provide a method for copying a contiguous symmetric data  object  from  a
       different  PE  to  a  contiguous  data  object on the local PE.  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 delivered to the dest
       array on the local PE.

       The arguments are as follows:

       dest   Local data object to be updated.

       source Data object on the PE identified by pe that contains the data to  be  copied.  This
              data object must be remotely accessible.

       nelems Number of elements in the target and source arrays. len must be of type integer. 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 Fortran.
       PROGRAM REDUCTION
         REAL VALUES, SUM
         COMMON /C/ VALUES
         REAL WORK

         CALL START_PES(0) ! ALLOW ANY NUMBER OF PES
         VALUES = MY_PE() ! INITIALIZE IT TO SOMETHING
         CALL SHMEM_BARRIER_ALL
         SUM = 0.0
         DO I = 0,NUM_PES()-1
           CALL SHMEM_REAL_GET_NBI(WORK, VALUES, 1, I)
           CALL SHMEM_QUIET                ! wait for delivery
           SUM = SUM + WORK
         ENDDO
         PRINT *, 'PE ', MY_PE(), ' COMPUTED SUM=', SUM
         CALL SHMEM_BARRIER_ALL
       END
