The traditional directory organization that maintains a full valid bit vector per directory entry is unsuitable for large-scale machines due to high storage overhead. This thesis proposes several alternate organizations. Limited pointers directories replace the bit vector with several pointers that indicate those caches containing the data. Although this scheme performs well across a wide range of workloads, its performance does not improve as the read/write ratio becomes very large. To address… CONTINUE READING
