This paper deals with the dependability evaluation of a Multipurpose, Multiprocessor System (MMS) under investigation by a system manufacturer. MMS is symmetric with a DSM and a CC-NUMA. As the system is scalable, we consider two architectures: a reference one composed of four nodes and an extended one with an additional spare node. A set of dependability and performability measures is evaluated for these architectures with two categories of application users, accepting different service degradation levels. Modeling is based on GSPN to which reward rates are added to evaluate performability measures. The originality of our approach is the clear separation between the architectural and the service concerns. The results allow us to quantify the influence of the main parameters and to compare the dependability of the systems under consideration. They can thus be used for supporting the manufacturer design choices as well as the potential user configuration choices.
