Diagram of the implementation of the structural plasticity model in NEST. In (1) the number of synaptic elements is calculated depending on the electrical activity of the neuron. These calculations are optimized using MPI and OpenMP. In (2) the structural plasticity manager gathers the number of synaptic elements per neuron using MPI directives and in (3) creates or deletes synapses to update the connections between neurons using MPI and OpenMP.
