Cache coherence directory eviction mechanisms are described for use in computer systems having a plurality of multiprocessor clusters. Interaction among the clusters is facilitated by a cache coherence controller in each cluster. A cache coherence directory is associated with each cache coherence controller identifying memory lines associated with the local cluster which are cached in remote clusters. An eviction manager is operable to designate one of the entries in the cache coherence directory to be evicted and maintain the designated entry in the cache coherence directory at least until a serialization point allows an eviction transaction corresponding to the designated entry to proceed.
