Abstract

Efficient interprocessor communication is a key parameter to achieve high performance in distributed memory multicomputer networks. Thus, modelling and analysing message communication latency is critical for optimizing the performance of interprocessor communications. To demonstrate how to achieve efficient (low latency) interprocessor communication, we have developed generalized stochastic Petri net (GSPN) routing models for congestion-prone communication patterns occurring in multicomputer networks. Under congestion-prone adjacent and non-adjacent node communication patterns, we use our developed GSPN routing models to study the effects of congestion (arising due to problems such as buffer overflow and traffic contention) on the message communication latency of multicomputer networks. This modelling has been carried out for mesh multicomputer networks employing the packet switching technique.
