YAWNS (yet another windowing network simulator), a parallel simulator designed to allow rapid development of various large-scale simulation models used in parallel simulation research, is described. YAWNS provides mechanisms for aggregating many logical processes (LPs) onto a single processors, for synchronizing those LPs and supporting their communications, and for controlling the execution of events. YAWNS is built around a synchronous synchronization protocol, and it clearly defines an interface with the LP processing routines. YAWNS demands that the LP programmer provide it with a small amount of readily accessible information. YAWNS is presently being implemented on an Intel iPSC/2, and it will serve as a basic testbed for experiments in parallel simulation.
