PyNN (pronounced 'pine' ) is a Python package for simulator-independent specification of neuronal network models.
The API has two parts, a low-level, procedural API, similar to that in PyNEST (functions create(), connect(), set(), record(), record_v()), and a high-level, object-oriented API (classes Population and Projection, which have methods like set(), record(), setWeights(), etc.).
The low-level API is good for small networks, and perhaps gives more flexibility. The high-level API is good for hiding the details and the book-keeping, and is intended eventually to have a one-to-one mapping with NeuroML.
The other thing that is required to write a model once and run it on multiple simulators is standard cell models. PyNN translates standard cell-model names and parameter names into simulator-specific names, e.g. standard model IF_curr_alpha is iaf_neuron in NEST and StandardIF in NEURON, while SpikeSourcePoisson is a poisson_generator in NEST and a NetStim in NEURON. Only a few cell models have been implemented so far.
PyNN is a work in progress, but is already being used for several large-scale simulation projects. The current stable release of the API is 0.3, but we recommend using the latest version from the Subversion repository since it has many features not available in 0.3.
The code is released under the CeCILL licence.
