NEURON along with other systems simulators is increasingly being used to simulate neural systems where the complexity demands massive parallel implementations. NEURON's ParallelContext allows parallelizing models using MPI. However, when using NEURON models in a docker container, this parallelization does not work out-of-the-box. We propose an architecture for MPI parallelization of NEURON models using docker swarm. We integrate this on our NEUROiD platform and obtain almost 16x improvement in simulation time on our cluster. © 2020 IEEE.
