Winsim: A tool for performance evaluation of parallel and distributed systems

Abstract

A simulation system Winsim for modeling of parallel and distributed systems is presented. Winsim is based on a class of extended Petri nets, has a simple graphical user interface, high level programming language possibilities for complex data processing, enables simulation of systems consisting of a large number of processes, and provides fast simulation. The paper considers the basic features of the system, outlines its architecture, and gives an example of a simulation model of a distributed mutual exclusion algorithm developed and implemented in Winsim.
