<H2>Overview</H2>

Text filter that demonstrates class pipeline. Example program reads a file
|
|
containing decimal integers in text format, and changes each to its square.

Two additional targets for this example:
|
|
<DL>
|
|
<DT><TT>make gen_input</TT>
|
|
<DD>Create an input generator program that prints out a sequence of integers.
|
|
<DT><TT>make input.txt</TT>
|
|
<DD>Create an input file for the example (with help of <TT>gen_input</TT>).
|

</DL>

|
<H2>Usage</H2>
|
|
<DL>
|
|
<DT><TT>square <I>-h</I></TT>
|
|
<DD>Prints the help for command line options
|
|
<DT><TT>square [<I>n-of-threads</I>=value] [<I>input-file</I>=value] [<I>output-file</I>=value] [<I>max-slice-size</I>=value] [<I>silent</I>]</TT>
|
|
<DT><TT>square [<I>n-of-threads</I> [<I>input-file</I> [<I>output-file</I> [<I>max-slice-size</I>]]]] [<I>silent</I>]</TT>
|
|
<DD><I>n-of-threads</I> is the number of threads to use; a range of the form <I>low</I>[:<I>high</I>], where low and optional high are non-negative integers or 'auto' for the TBB default.<BR>
|
|
<I>input-file</I> is an input file name.<BR>
|
|
<I>output-file</I> is an output file name. <BR>
|
|
<I>max-slice-size</I> is the maximum number of characters in one slice.<BR>
|
|
<I>silent</I> - no output except elapsed time.<BR>
|
|
<DT><TT>gen_input [<I>LN</I>] > <I>inputfile</I></TT>
|
|
<DD>Generate a file named <I>inputfile</I> consisting of <I>LN</I> lines each containing one integer.
|
|
If not specified, <I>LN</I> is assumed to be 1000000.
|
|
|
|
<DT>To run a short version of this example, e.g., for use with Intel® Parallel Inspector:
|
|
<DD>Build a <I>debug</I> version of the example
|
|
(see the <A HREF=../../index.html#build>build directions</A>).
|
|
<BR>Prepare an <I>inputfile</I> with about 5,000 lines of text (see the instruction above).
|
|
<BR>Run it with this <I>inputfile</I> and the desired number of threads,
|
|
e.g., <TT>square 4 <I>inputfile</I> <I>outputfile</I></TT>.
