We present a new arrangement of directory bits called the segment directory to improve directory storage efficiency: a segment directory can point to several sharing processors wi...
Caches enhance the performance of multiprocessors by reducing network trac and average memory access latency. However, cache-based systems must address the problem of cache coher...
As multiprocessors are scaled beyond single bus systems, there is renewed interest in directory-based cache coherence schemes. These schemes rely on a directory to keep track of a...
—The number of CPUs in chip multiprocessors is growing at the Moore’s Law rate, due to continued technology advances. However, new technologies pose serious reliability challen...
