The fault tolerance of multiprocessor systems with multistage interconnection networks under multiple faults in the network is studied. The fault tolerance is analyzed with respect to the criterion of dynamic full access (DFA) property of the processors in the system. A characterization of multiple faults in the Omega network is introduced and used to develop simple tests for the DFA capability
