Abstract: The Multi-Simulation Coordinator (MUSIC) is an INCF funded standard and library implementation that allows neuronal simulators or programs for stimulus generation, data analysis, or visualization to exchange data at run-time. To set up such a multi-simulation consisting of several simulators, the user has to specify the different parts of the network model in the native description or scripting languages of the respective simulators, and provide a configuration file that tells MUSIC what data has to be transported between which applications. This approach works well for connecting multiple already existing models written for different simulators. An example for using this is given in [1]. However, this approach requires the user to be familiar with the configuration languages of all simulators involved in the simulation. To alleviate this problem, we extended the application programming interface (API) of PyNN [2], to enable the simulator-independent specification of multi-simulator neuronal network models. In this contribution, we provide a detailed description of necessary changes to the existing software packages (i.e. NEST [3], NEURON [4] and PyNN) and the user experience for our prototype implementation of this API. The API allows the user to set up the network model using all of PyNN's high-level language constructs and abstracts away from the technical aspects of using the simulator's native MUSIC interfaces and setting up the multi-simulation.
