Here are some test examples to illustrate the usage of CoreNEURON API with NEURON:
This is a simple, single cell, serial Python example demonstrating the use of CoreNEURON. We first run a simulation with NEURON and record the voltage and membrane currents. Then, the same model is executed with CoreNEURON, and we make sure the same results are achieved. Note that in order to run this example you must build these mod files with
nrnivmodl -coreneuron. You can run this example as:
nrnivmodl -coreneuron mod # first compile mod files nrniv -python test_direct.py # run via nrniv x86_64/special -python test_direct.py # run via special python test_direct.py # run via python
This is the same example as above (
test_direct.py) but written using HOC.
This is similar to
test_direct.pyabove, but it can be run with MPI where each MPI process creates a single cell and connects it with a cell on another rank. Each rank records spikes and compares them between NEURON execution and CoreNEURON execution. It also demonstrates usage of the mpi4py Python module and NEURON’s native MPI API.
You can run this MPI example in different ways:
mpiexec -n <num_process> python test_spikes.py mpi4py # using mpi4py mpiexec -n <num_process> x86_64/special -mpi -python test_spikes.py # neuron internal MPI
- Ring network test:
This is a ring network model of Ball-and-Stick neurons which can be scaled arbitrarily for testing and benchmarking purpose. You can use this as a reference for porting your model, see the README file for detailed instructions.
