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 Intel® Threading Building Blocks. Most of the computations are deliberately silly and not expected to show any speedup on multiprocessors.

System Requirements

For the most up to date system requirements, see the release notes.

Files
Fibonacci.cpp
Source code for example.
Makefile
Makefile for building the example.
Directories
msvs
Contains Microsoft* Visual Studio* workspace for building and running the example (Windows* systems only).
xcode
Contains Xcode* IDE workspace for building and running the example (macOS* systems only).

For information about the minimum supported version of IDE, see release notes.

Build instructions

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 instructions).
Run it with a small fibonacci number and the desired number of threads, e.g., fibonacci 100 4.
