CMS: An integrated simulation environment

A simulation environment is described which allows the execution of programs written for a Connection Machine (CM). The Connection Machine simulator (CMS) simulation environment provides several tools for empirical analysis of these parallel algorithms. It provides performance statistics on the simulated Connection Machine as it runs different user programs. The behavior of the simulated environment is governed by configuration parameters which can be altered to find the optimal Connection Machine configuration in which to run an algorithm. The CMS simulation environment runs on the Sun workstation and uses the windowing and mouse interfaces provided. Different windows allow the user to view different parts of the simulated Connection Machine at the same time. Also included is a discussion of the internals of the simulator and the reasoning behind the methods used
