.SH DESCRIPTION
.sp
The shmem_fetch functions perform an atomic fetch operation. They return
the contents of the \fBtarget\fP as an atomic operation.
.sp
The arguments are as follows:
.INDENT 0.0
.TP
.B target
The remotely accessible data object to be fetched from the remote PE.
.TP
.B pe
An integer that indicates the PE number from which \fItarget\fP is to be
fetched. If you are using Fortran, it must be a default integer
value.
.UNINDENT
.SH RETURN VALUES
.sp
The contents at the \fItarget\fP address on the remote PE. The data type of
the return value is the same as the the type of the remote data object.
