Design and performance of directory caches for scalable shared memory multiprocessors

The performance of directory cache using parallel applications from the SPLASH-2 suite is studied and various cache design parameters are investigated. The results indicate that the directory cache size requirements grow sub-linearly with the increase in the application's data set size including the performance advantage of multientry directory. In addition, the impact of the associativity of the directory caches on performance is less than that of the size and line size.
