Abstract: This paper presents a cluster-based PMBK (CPMBK) multiprocessor system and analyses its performance of bandwidth. This interconnection network offers advantages such as more flexibility. Two situations are considered: (1), a processor is equally likely to address any one of the memory modules, (2), a processor has a few favourite memory modules. The results derived show that the cluster-based PMBK multiprocessor system performs well and is fairly close to a typical partial multiple bus system with K classes (PMBK) for high rates of favourite requests. The number of connections of this system is also evaluated and compared with those of other systems. It shows that the cluster-based PMBK system can reduce the network cost and complexity without significantly reducing the performance compared with those of crossbar, PPMB, PMBK and cluster-based crossbar systems.

Keywords: multiprocessor; effective memory bandwidth; interconnection network; performance analysis; hierarchy.
