This document describes a simulator for modeling execution of parallel programs on a mutliprocessor. The simulator executes a set of programs as if each were run on a separate processor, and compiles statistics for the entire run. a portion of the simulator, known as the "switch model", simulates the exchange of messages among the processors through an interconnection network. The simulator was developed to allow different types of interconnection hardware (e.g. packet switches, crossbars, etc.) to be modelled by simply "plugging in" the appropriate switch model. Applications are programmed as a set of communicating tasks (processes). The interface seen by the applications programmer is discussed, and in particular, the communications mechanism is described in detail. Examples are given. Finally, the implementation of Simon is described.
