GSPN models of concurrent architectures with mesh topology

Describes a GSPN-based approach to performance evaluation of parallel MIMD architectures with mesh interconnection schemes. The analysis considers regular computational structures in which data exchange and inter-process synchronization require communication only among processors that are physically connected. The effectiveness of the modeling technique for this class of architectures is shown through examples considering both the effect of the interaction policies among processes and the benefit of multitrasking on the global efficiency of the architecture
