## Overview

Parallel version of convex hull algorithm (quick hull).

## Files

convex_hull_sample.cpp
  Source code for TBB version of example.
convex_hull_bench.cpp
  Source code for version of example that compares serial and TBB buffered and unbuffered implementations.
convex_hull.h
  Include file for example.
Makefile
  Makefile for building example.

## Directories

msvs
  Contains Microsoft* Visual Studio* 2005 workspace for building and running the example.
xcode
  Contains Xcode* IDE workspace for building and running the example.

## To Build

General build directions can be found here.

## Usage

`convex_hull_sample [S] [M[:N]] [-v]`
  S is the number of points (problem size). M:N are a range of numbers of threads to be used. Use the -v option to turn on verbose output.
To run a short version of this example, e.g., for use with Intel® Threading Tools:
  Build a debug version of the example (see the build directions).
  Run it with a small problem size and the desired number of threads, e.g., `convex_hull_sample 500000 4`.
