Objectsim - The Conceptual Model Of A Generic Parallel & Distributed Computer Architecture Simulator.

This paper describes the design and implementation of OBJECTSIM. OBJECTSIM overcomes the narrow focus of previous architecture simulators by specifying a small number of generic simulation objects (and an associated hierarchy) that are capable of implementing a wide range of target systems. Target systems range from multi-stage interconnection networks (MINs) and ATM and BISDN networks, through to bus and network based multiprocessors. OBJECTSIM also provides trace, execution and stochastic driver mechanisms. To simulate large systems ( > 256 nodes ) OBJECTSIM uses a distributed object oriented simulation kernel. The combination of this kernel with the object hierarchy method makes OBJECTSIM a unique contribution to the field. OBJECTSIM runs on a network of SUN stations
