Distributed computing based on Petri networks

Quantica

Distributed computing based on Petri networks (PNs)

What is quantica?

Quantica is an Python open-source framework for modeling distributed computing based on PNs theory.

Quantica is compatible with Python versions >= 3.8

How does it work ?

As explained in PN's theory, a network consists of places and transitions. Transitions are event-based conditions which allow the places to be enabled.

Custom code execution

Places are the basic units of custom code execution. The code execution in Places is determined by the presence of tokens. In Quantica whenever a QPlace (a place in PN theory) receives a token, it executes its relative task immediately.

How to create a QNet ?

A simple network constisting of a place and a transition is shown below

from quantica.core import QNet

net = QNet('MyQNet')
P0 = net.createPlace(init_tokens=1)
T0 = net.createTransition()
net.connect(P0, T0, weight=1)
