Requirements

• Linux Ubuntu >= 18.04
• Boost >= 1.67
• CUDA >= 9.2
• python >= 3.6
• GNU make >= 4.1
• gcc >= 7.3.0

Installation

1) install boost

• download the latest version from: http://www.boost.org/users/download/
• unzip tar.bz2 in $HOME/source:

tar xvjf ~/Downloads/boost*.tar.bz2 -C ~/source
cd ~/source/boost*
./bootstrap.sh
sudo ./b2 install

2) CUDA installation

(only required if you want to use GPU-accelerated code, otherwise skip to 3)

• get .run file(s) (possible patches) from cuda repository https://developer.nvidia.com/cuda-toolkit
• save both in ~/cuda

chmod u+x ~/cuda/*
sudo service lightdm stop
sudo ./cuda_*.run --silent --override --toolkit --samples

3) python installation

sudo apt-get install python3 python3-pip
sudo -H pip3 install --upgrade pip
sudo -H pip3 install jupyter numpy matplotlib

4) program

for the CPU version:

cd coupled_oscillators_solver
# adapt line 13 in the makefile for CPU or GPU version by commenting it
make

Usage

1) prepare and run simulation

• modify .ini file in ini directory to your liking
• run program via

./coupled_oscillators_solver.exe --ini ../ini/<nameOfIni>.ini

• for example:

./coupled_oscillators_solver.exe --ini ../ini/phase_global.ini

2) to run the visulization, enter on the commandline:

jupyter notebook

and navigate to the directory with the .ipynb file

• activate cells with shift+enter
• enter name and continue
