Simultaneous consideration of both performance and reliability issues is important in the choice of computer architectures for real-time aerospace applications.One of the requirements for such a fault-tolerant computer system is the characteristic of graceful degradation.A shared and replicated resources computing system represents such an architecture.In this paper, a combinatorial models used for the evaluation of the instruction execution rate of a degradable, replicated resources computing system such as a modular multi processor system. Next a method is presented to evaluate the computation reliability of such a system utilizing a reliability graph model and the instruction execution rate.Finally, this computation reliability measure, Which simultaneously describes both performance and reliability, is applied as a constraint in an architecture optimization model for such computing systems.
