\section{The \code{ordered} Clause and the \code{ordered} Construct}
|
|
\label{sec:ordered}
|
|
|
|
Ordered constructs are useful for sequentially ordering the output from work that
|
|
is done in parallel. The following program prints out the indices in sequential
|
|
order:
|
|
|
|
\cexample{ordered}{1}
|
|
|
|
\fexample{ordered}{1}
|
|
|
|
It is possible to have multiple \code{ordered} constructs within a loop region
|
|
with the \code{ordered} clause specified. The first example is non-conforming
|
|
because all iterations execute two \code{ordered} regions. An iteration of a
|
|
loop must not execute more than one \code{ordered} region:
|
|
|
|
\cexample{ordered}{2}
|
|
|
|
\fexample{ordered}{2}
|
|
|
|
The following is a conforming example with more than one \code{ordered} construct.
|
|
Each iteration will execute only one \code{ordered} region:
|
|
|
|
\cexample{ordered}{3}
|
|
|
|
\fexample{ordered}{3}
