## Overview

This directory contains an example that computes Fibonacci numbers in several different ways. The purpose of the example is to exercise every include file and class in Threading Building Blocks. Most of the computations are deliberately silly and not expected to show any speedup on multiprocessors.

## Files

Fibonacci.cpp
  Source code 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

`fibonacci K [M[:N]] [R]`
  Calculates the K-th fibonacci number. M and N are a range of numbers of threads to be used. R is the number of times to repeat the calculation.
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 fibonacci number and the desired number of threads, e.g., `fibonacci 100 4`.
