Abstract: The paper presents a part of a larger project aiming at developing a performance-oriented parallel system design method based on Petri nets and actually used in industrial frameworks. As modularity and compositionality are crucial for reusability, former work proposed the process-box as a net-based construct for modeling concurrent applications such as Occam programs. The paper extends the approach by introducing the resource-box and showing how the two constructs are jointly used for modeling a simple architecture and its workload. The example also illustrates how the proposed approach enhances the effectiveness and reusability of GSPNs, the most popular Petri-net-based formalism for performance evaluation.
