Abstract

Multiprocessor system models are extensively used in modelling transaction processing systems, nodes in communication networks, and flexible machine shops with groups of machines. Such systems clearly, are prone to break-downs. Even if cover is provided with some probability c, there will be rebooting and/or reconfiguration delays to resume operation following the break-down of a processor. In this paper, the performance modelling of a multiprocessor system, with identical processors, serving a stream of arriving jobs is considered. To account for delays due to reconfiguration and rebooting, such systems are modelled and solved for exact performability measures for both bounded and unbounded queuing systems. © ECMS, 2005.
