Simulação Paralela de Redes de Petri
Abstract
Petri nets (PN) have been widely used to model novel computer systems. They can naturally represent important features of these systems, such as: concurrency, synchronization and blocking. Stochastic Petri Nets (SPN) add the notion of time to the original Petri net model. SPN is an appropriate model to represent performance of computer systems. However, in some cases, due to the combinatorial explosion of the state space of the model, an analytic solution of the Petri net becomes unfeasible. Thus, simulation appears as an alternative solution to solve large Petri net models. This article presents a way of using many processors in parallel to obtain a solution to RP models.
