  4. Abstract:
  5. Current massively parallel systems are often composed of hundreds or thousand of components (such as routers, channels and connectors) that collectively possess failure rates higher than what arise in the ordinary systems. Therefore, these systems are required to he equipped with fault-tolerant mechanisms to ensure that the system will keep running in a degraded made until the failed component in repaired. Normally, the faulty components are coalesced into fault regions which may be classified into two major categories: convex and concave regions. In this paper, we propose the first general solution to calculate the probability of occurrences of common fault patterns in torus networks which includes both convex (□-shaped, □-shaped, □-shaped) and concave (L-shaped, T-shaped, +-shaped, H-shaped) regions. © 2006 IEEE
