Abstract :
The impact of increased unreliability of network components on the performance of a cluster-based multiprocessor system (CBMS) is investigated. A generalized model which has been developed for computing the closed-form bandwidth expressions for fault-free as well as faulty systems is discussed. Performance curves are given which illustrate the degradation when unreliability is increased in terms of the number of cluster-network failures. The architecture of the CBMS along with background material for the analysis is described. A special case called private and favorite memory is discussed
