Fast and Scalable Security Support for Directory-Based Distributed Shared Memory

Traditional Directory-based cache coherence protocol is far from optimal for large-scale cache coherent shared memory multiprocessors due to the increasing latency to access directories stored in DRAM memory. Instead of keeping directories in main ...

There are two important hurdles that restrict the scalability of directory-based shared-memory multiprocessors: the directory memory overhead and the long L2 miss latencies due to the indirection introduced by the accesses to directory information, ...

Directory-based cache coherence protocol is accepted as the common technique in large scale shared memory multiprocessors because of its scalability. Although it was extensively studied in the past, however, the memory overhead and long miss penalty ...
