fractal-demo is a distributed fractal-calculator based on OpenCL, Qt 4 and CAF. Controll unit, calculation units and server/screen unit are distributed. OpenCL allows the usage of GPUs.

Since Qt is used as a GUI make sure cmake finds the Qt bin.
- CAF: CAF
- Qt: qt.nokia.com
- GCC >= 4.8
git clone https://github.com/actor-framework/fractal-demo.git
cd fractal-demo
./configure
make
Cmake needs to find qt. If it does not by default, add the qt bin directory to your PATH.
export PATH=<PATH_TO_SDK>/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
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:portthe location of published workers. - Server starts first and workers connect with
-H server_domain:portto 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.
Tested on OSX, and Linux.
