Abstract. One way of dealing with transient faults that will affect the
interconnection network of future large-scale Chip Multiprocessor (CMP)
systems is by extending the cache coherence protocol. Fault tolerance at
the level of the cache coherence protocol has been proven to achieve very
low performance overhead in absence of faults while being able to support
very high fault rates. In this work, we compare two already proposed
