A Graphical Toolset for Performance-Oriented Design of Portable Parallel Software

. This paper describes a portable performance-oriented integrated toolset for parallel software development. This toolset is composed of a graphical design tool, a simulation tool, and a visualisation tool. The toolset helps the parallel programmer to choose between design alternatives based on their predicted performances. The graphical design tool helps users who are not familiar with parallel programming models (such as PVM) to automatically generate executable parallel code. The target parallel system models a virtual machine composed of a cluster of workstations interconnected by a local area network. The simulation model architecture is modular and extensible which allows the re-configuration of the platform. The model description and the validation experiments which have been conducted to assess the correctness and the accuracy of the model are also presented. 1 Introduction A major obstacle to the widespread adoption of parallel computing in industry is the difficulty in progr..
