Abstract :
The inherent fault tolerances of systems based on nonredundant multistage interconnection networks (MINs) is investigated. Graph models are used to describe the system, indicate faults, study their effects, and aid in mathematical formulation of these effects. Methodical terminology for defining functionality of two-sided-MIN-based multicomputer systems and specifying their fault tolerance of such systems is analyzed. The effects of a single faulty vertex and a single faulty edge are studied, and single fault tolerance, with respect to various definitions of system functionality, is evaluated. Multiple faults are analyzed. A practical example of the banyan network used in the Texas reconfigurable array computer (TRAC) and its fault tolerance capabilities are given
