Stanford DASH Architecture: Cluster Simulation Model

The Stanford DASH architecture was designed to prove the feasibility of building a scaleable high performance machine with multiple coherent caches and a single address space. There are currently two HASE simulation models of parts of the DASH architecture, one modelling a single node and one modelling a cluster of four nodes. These models are designed to demonstrate the cache coherency protocols used in the DASH. The Cluster model demonstrates the snoopy bus protocol.

The HASE DASH Cluster Architecture Website describes the DASH architecture and explains how the HASE Cluster model works.
