Auryn is a simulator for spiking neural networks with plastic synapses. It is free and open source software optimized to simulate spiking neural networks with plasticity. Some examples are Vogels et al., Science, 2011; Zenke et al., Nature Communications, 2015; and more.
As a spiking neural network simulator Auryn is complementary to other simulators such as NEST and Brian. Instead of focusing on large-scale simulations or ease of model development, Auryn's main focus lies on simulation speed to efficiently simulate small or medium sized network models with plasticity over extended periods of simulated time (hours to days). To that end, Auryn is optimized to run efficiently on shared memory machines and small clusters. Auryn is written in C++ and uses MPI for parallel execution. Moreover, it supports Intel's Xeon Phi architecture.
This wiki aims at providing examples and documentation for Auryn users and developers. To get started take a look at quick start and check out the Examples pages. Here you will also find most of the simulation code of published work. The best place for questions is the support forum.
