EDPEPPS - AN ENVIRONMENT FOR OPTIMAL PARALLEL SOFTWARE-DESIGN

This paper describes an environment for performance-oriented design of portable parallel software. The environment consists of a graphical d esign tool based on the PVM communication library for building paralle l algorithms, a state-of-the-art simulation engine and a visualisation tool for animation of program execution and visualisation of platform and network performance measures and statistics. The toolset is used to model a virtual machine composed of a cluster of workstations inter connected by a local area network. The simulation model used is modula r and its components are interchangeable which allows easy re-configur ation of the platform. The model is validated using experiments on the COMMS1 benchmark from the Parkbench suite, and a standard image proce ssing algorithm with maximum errors of 1% and 10% respectively.
