摘要

Currently, directory-based cache coherence protocols are widely adopted in DSM systems. However, with the scaling of system size, directory-based protocols are also confronted with the problem of scalability. With the analysis of factors that affect the scalability of directory protocols, we propose a two-level directory organization solution based on directory cache in this paper. Simulation result shows that this directory organization can efficiently reduce storage space occupied by directory information to enable good scalability for the implementation of the protocol, with the performance of the system being considered.
