devices.dynapse.mapper(graph: rockpool.graph.graph_base.GraphModule, in_place=False, clustering_method: str = 'greedy', n_cluster: Optional[int] = None, max_neuron_per_cluster: int = 256) Dict[str, float][source]

mapper maps a computational graph onto Dynap-SE2 architecture. Each neural core shares a parameter group in Dynap-SE2. Therefore neurons inside the same core operates with the same current setting. mapper function cluster parameters in groups and allocates an hardware posititon for neurons.

  • clustering_method (str, optional) – the clustering approach. "random" or "greedy", defaults to "greedy"

  • n_cluster (int, optional) – number of clusters. minimum number of clusters possible if None, defaults to None

  • max_neuron_per_cluster (int, optional) – maximum number of neurons allowed per cluster, defaults to NUM_NEURONS
