In this paper we study the ability of array-based networks to tolerate worst-case faults. We show that an N × N two-dimensional array can sustain N1-∈ worst-case faults for any fixed ∈ > 0, and still emulate T steps of a fully functioning N × N array in O(T + N) steps, i.e., with only constant slowdown. Previously, it was known only that an array could tolerate a constant number of faults with constant slowdown. We also show that if faulty nodes are allowed to communicate, but not compute, then an N-node one-dimensional array can tolerate logk N worst-case faults, for any constant k > 0, and still emulate a fault-free array with constant slowdown, and this bound is tight.
