Behavioural and performance analysis is a fundamental problem in the development of parallel (and distributed) programs. To address this problem, models and supporting environments are required to enable designers to build and analyse their programs. The model we put forward in this paper combines graphical and textual representations of the program structure and uses discrete-event simulation for performance and behaviour predictions. A graphical environment supports our model, providing, amongst other features, a graphical editor, a simulation engine and a performance and behaviour visualisation tool. A number of case studies using this environment are also provided for illustration and validation of our model. Prediction errors observed in comparisons of real execution and simulation of case studies have accuracy to within 10%.
