fractal-demo

============

fractal-demo is a distributed fractal-calculator based on OpenCL, [Qt 4](http://qt.nokia.com/) and [CAF](https://github.com/actor-framework/actor-framework). Controll unit, calculation units and server/screen unit are distributed. OpenCL allows the usage of GPUs.

Dependencies

------------

Since Qt is used as a GUI make sure cmake finds the Qt bin.

* __CAF__: [CAF](https://github.com/actor-framework/actor-framework)

* __Qt__: [qt.nokia.com](http://qt.nokia.com/)

Compiler

--------

* GCC >= 4.8

Get the source

--------------

    git clone https://github.com/actor-framework/fractal-demo.git

    cd fractal-demo

Build the apps

--------------

    ./configure

    make

Cmake needs to find qt. If it does not by default, add the qt bin directory to your PATH.

    

    export PATH=/QtSDK/Desktop/Qt/4.8.1/gcc/bin/:$PATH

It is possibile to use OpenCL for the calculation. To do this you need to compile libcppa and

this project with the OpenCL option.

    ./configure --with-opencl

    make

Usage:

------

fractal-demo allows you two ways to make a connection between worker and server. 

* Workers are published first and than the server gets with `-n domain:port` the location of published workers.

* Server starts first and workers connect with `-H server_domain:port` to the server.

In this example the second point is shown.

To calculate, controll and server on one computer without openCL:

    # Terminal 1

    # start server and publish at port 7000

    .build/bin/fractal-demo -s -p 7000

    # Terminal 2

    # publish two workers (CPU) on port 7000 of your client.

    .build/bin/fractal-demo -w 2 -H localhost:7000

    

    # Terminal 3

    # start controller with server on localhost

    .build/bin/fractal-demo -c -H localhost

Note: Of course you can start everything in one terminal. To do this, append `&` to end of each command. If you want to quit them all you can just type: `killall fractal-cppa`.

In case you want to enable OpenCL, add the -o flag to client start.

    .build/bin/fractal-demo -w 2 -H localhost:7000 -o

As above-mentioned, fractal-demo is distributed. That means, you can split up each terminal on diffrent computer and add even more workers trough diffrent computer.
