The simulation of a P system with current computers is a quite complex task. P systems are intrinsically non deterministic computational devices and therefore their computation trees are difficult to store and handle with one-processor (or bounded number of processors) computers. Nevertheless, there exists a first generation of simulators which can be successfully used for pedagogical purposes and also as assistant tools for researchers. This paper summarizes one of these simulators, presenting the state-of-the-art of the available software for simulating (different variants of) cell-like P systems.
