DESCRIPTION

       These  routines  transfer  nelems  elements  of  the  data object at address source on the
       calling PE, to the data object at address target on the  remote  PE  pe.   These  routines
       start the remote transfer and may return before the data is delivered to the remote PE.

       The  delivery  of data into the data object on the destination PE from different put calls
       may occur in any order. Because of this, two successive put operations  may  deliver  data
       out of order unless a call to shmem_fence(3) is introduced between the two calls.

       The arguments are as follows:

       target 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.

       len    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.

       The  target  and source data objects must conform to certain typing constraints, which are
       as follows:

       shmem_putmem: Fortran: Any noncharacter type. C: Any data type. len is scaled in
              bytes.

       shmem_put4, shmem_put32: Any noncharacter type that has a storage size
              equal to 32 bits.

       shmem_put8, shmem_put64: Any noncharacter type that has a storage size
              equal to 64 bits.

       shmem_put128: Any noncharacter type that has a storage size equal to 128
              bits.

       shmem_short_put: Elements of type short.

       shmem_int_put: Elements of type int.

       shmem_long_put: Elements of type long.

       shmem_longlong_put: Elements of type long long.

       shmem_float_put: Elements of type float.

       shmem_double_put: Elements of type double.

       shmem_longdouble_put: Elements of type long double.

       SHMEM_CHARACTER_PUT: Elements of type character. len is the number of
              characters to transfer. The actual character  lengths  of  the  source  and  target
              variables are ignored.

       SHMEM_COMPLEX_PUT: Elements of type complex of default size.

       SHMEM_DOUBLE_PUT: (Fortran) Elements of type double precision.

       SHMEM_INTEGER_PUT: Elements of type integer.

       SHMEM_LOGICAL_PUT: Elements of type logical.

       SHMEM_REAL_PUT: Elements of type real.
              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).

EXAMPLES

       The following shmem_put example is for C/C++ programs:
       #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(target, source, 10, 1);
         }
         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]);
       }
