<H2>Overview</H2>

<H2>Files</H2>
<DL>
<DT><A HREF="convex_hull_sample.cpp">convex_hull_sample.cpp</A>
<DD>Source code for TBB version of example.
<DT><A HREF="convex_hull_bench.cpp">convex_hull_bench.cpp</A>
<DD>Source code for version of example that compares serial and TBB buffered and unbuffered implementations.
<DT><A HREF="convex_hull.h">convex_hull.h</A>
<DD>Include file for example.
<DT><A HREF="Makefile">Makefile</A>
<DD>Makefile for building example.
</DL>

<H2>Directories</H2>
<DL>
<DT><A HREF="msvs">msvs</A>
<DD>Contains Microsoft* Visual Studio* 2005 workspace for building and running the example.
<DT><A HREF="xcode">xcode</A>
<DD>Contains Xcode* IDE workspace for building and running the example.

<H2>To Build</H2>
General build directions can be found <A HREF=../../index.html#build>here</A>.

<H2>Usage</H2>
<DL>
<DT><TT>convex_hull_sample [<I>S</I>] [<I>M</I>[:<I>N</I>]] [-v]</TT>
<DD><I>S</I> is the number of points (problem size).
    <I>M:N</I> are a range of numbers of threads to be used.
    Use the -v option to turn on verbose output.
<DT>To run a short version of this example, e.g., for use with Intel&reg; Threading Tools:
<DD>Build a <I>debug</I> version of the example
    (see the <A HREF=../../index.html#build>build directions</A>).
    <BR>Run it with a small problem size and the desired number of threads, e.g., <TT>convex_hull_sample 500000 4</TT>.
