Bus based multiprocessor

WebJul 23, 2024 · They are realized as single bus-based multiprocessors called clusters. The Dash architecture also combines the snoopy cache protocol and the directory scheme. A snooping scheme ensures the consistency of caches inside the clusters, while the directory scheme maintains consistency across clusters.
