Auryn logo


Auryn is Simulator for recurrent spiking neural networks with synaptic plasticity. It comes with the GPLv3 (please see COPYING).

Quick start

Note, Auryn needs a C++ compiler, the boost libraries ( with MPI support installed. To download and compile the examples under Linux try:

sudo apt-get install cmake git build-essential libboost-all-dev
git clone && cd auryn/build/release
./ && make

Run a first network simulation

cd examples
./sim_coba_benchmark --dir .

will run the Vogels Abbott benchmark, a balanced network model with conductance based synapses. Spiking activity is written to files with the extension 'ras'.

If you have gnuplot installed, you can visualize the output of the simulation follows:

echo "set xlabel 'Time [s]'; plot [1:2] 'coba.0.e.ras' with dots lc rgb 'black'" | gnuplot -p

Spike raster plot

Here time in seconds is plotted on the x-asis and neuron id on the y-axis.

Install as a library

To install Auryn as a library run:

sudo make install

which will put it under /usr/local/ or for a local install

make DESTDIR=./your/dir/ install
