Stanford DASH Architecture Simulation Models

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 HASE DASH Architecture Website describes the DASH architecture and explains how the HASE models work. It also has links to the WebHASE viewer applets and the JavaHASE simulation applets for the models.

The JavaHASE simulation applets for the DASH simulation models can be accessed from the HASE DASH Architecture Website or directly from here:

• Dash Node Model

• Dash Cluster Model

The pre-run simulations of the DASH Architecture available via WebHASE can be accessed from the HASE DASH Architecture Website or directly from here:

• The HASE Dash Node Model models a node of the DASH architecture.

• The HASE Dash Cluster Model models four nodes of the DASH architecture connected via a Cluster Bus.
