.SH DESCRIPTION
.sp
The routines return after posting the operation. The operation is
considered complete after a subsequent call to \fI\%shmem_quiet\fP\&. At the
completion of \fI\%shmem_quiet\fP, 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
\fI\%shmem_fence\fP is introduced between the two calls.
.sp
The arguments are as follows:
.INDENT 0.0
.TP
.B dest
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 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.
.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
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 NOTES
.sp
See \fIintro_shmem\fP(3) for a definition of the term remotely accessible.
.SH EXAMPLES
.sp
Consider this simple example for C.
