The Mermaid Architecture-workbench for Multicomputers

The large design space of modern computer architectures calls for performance modelling tools to facilitate the evaluation of different alternatives. In this paper, we present an overview of the Mermaid multicomputer simulation environment. This environment allows for the evaluation of a wide range of architectural design tradeoffs while delivering good simulation performance. To achieve this, simulation takes place at a level of abstract machine instructions rather than at the level of real instructions like many other simulation systems do. Moreover, a less detailed mode of simulation, which has some similarities with the commonly applied direct execution simulation technique, is also provided. So when accuracy is not the primary objective, this simulation mode can yield high simulation efficiency. Therefore, Mermaid makes both fast prototyping and accurate evaluation of multicomputer architectures feasible.
