The Wisconsin Multicube: a new large-scale cache-coherent multiprocessor

The Wisconsin Multicube, a large-scale, shared-memory multiprocessor architecture that uses a snooping cache protocol over a grid of buses, is introduced. The authors describe its cache coherence protocol and discuss efficient synchronization primitive. Then they discuss a number of other important design issues and modeling results. They introduce the general Multicube topology and discuss the scalability of the Wisconsin Multicube. A formal description of the cache consistency protocol is also given.<
