.SH DESCRIPTION
.sp
These routines transfer \fBnelems\fP elements of the data object at
address \fBsource\fP on the calling PE, to the data object at address
\fBtarget\fP on the remote PE \fBpe\fP\&. These routines start the remote
transfer and may return before the data is delivered to the remote PE.
.sp
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
\fI\%shmem_fence\fP(3) is introduced between the two calls.
.sp
The arguments are as follows:
.INDENT 0.0
.TP
.B target
Data object to be updated on the remote PE. This data object must be
remotely accessible.
.TP
.B source
Data object containing the data to be copied.
.TP
.B 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.
.TP
.B 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.
.UNINDENT
.sp
The target and source data objects must conform to certain typing
constraints, which are as follows:
.INDENT 0.0
.TP
.B \fI\%shmem_putmem\fP: Fortran: Any noncharacter type. C: Any data type. len is scaled in
bytes.
.TP
.B shmem_put4, \fI\%shmem_put32\fP:** Any noncharacter type that has a storage size
equal to 32 bits.
.TP
.B shmem_put8, \fI\%shmem_put64\fP:** Any noncharacter type that has a storage size
equal to 64 bits.
.TP
.B \fI\%shmem_put128\fP:** Any noncharacter type that has a storage size equal to 128
bits.
.UNINDENT
.sp
\fI\%shmem_short_put\fP:** Elements of type short.
.sp
\fI\%shmem_int_put\fP:** Elements of type int.
.sp
\fI\%shmem_long_put\fP:** Elements of type long.
.sp
\fI\%shmem_longlong_put\fP:** Elements of type long long.
.sp
\fI\%shmem_float_put\fP:** Elements of type float.
.sp
\fI\%shmem_double_put\fP:** Elements of type double.
.sp
\fI\%shmem_longdouble_put\fP:** Elements of type long double.
.INDENT 0.0
.TP
\fBSHMEM_CHARACTER_PUT:\fP Elements of type character. len is the number of
characters to transfer. The actual character lengths of the source
and target variables are ignored.
.UNINDENT
.sp
\fBSHMEM_COMPLEX_PUT:\fP Elements of type complex of default size.
.sp
\fBSHMEM_DOUBLE_PUT:\fP (Fortran) Elements of type double precision.
.sp
\fBSHMEM_INTEGER_PUT:\fP Elements of type integer.
.sp
\fBSHMEM_LOGICAL_PUT:\fP Elements of type logical.
.INDENT 0.0
.TP
\fBSHMEM_REAL_PUT:\fP 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).

.SH EXAMPLES
.sp
The following shmem_put example is for C/C++ programs:
.INDENT 0.0
.INDENT 3.5
.sp
.EX
#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(\(dqtarget[0] on PE %d is %d\en\(dq, shmem_my_pe(), target[0]);
