Installation

You can easily install PythonPDEVS with the following command.

cd src
python setup.py install --user

Relationship with the original distribution

This is a fork from the last available/accessible official distribution from MSDL, University of Antwerp, from cca. 2026 April. Gradual improvements are ported back to this distribution. The list of changes can be reproduced from the closed issues.

Performance

For optimal performance results, we recommend the use of PyPy.

By default, PythonPDEVS is optimized for distributed simulation, therefore doing a lot of additional bookkeeping. For optimal performance in local simulations, we recommend the use of the minimal simulation kernel instead: just update all imports from

from pypdevs.simulator import Simulator
from pypdevs.DEVS import AtomicDEVS, CoupledDEVS

to

from pypdevs.minimal import Simulator
from pypdevs.minimal import AtomicDEVS, CoupledDEVS

Note that this disables many features.

Distributed simulation (optional)

To use distributed simulation capabilities, run the script install_mpi4py.sh to install the necessary MPI library and bindings.

Documentation

Detailed documentation of the installation and use of PythonPDEVS can be found in the PythonPDEVS documentation.
