VisuaLinda: A Framework and a System for Visualizing Parallel Linda Programs

This paper describes a framework and a system for visualizing parallel Linda programs. The system is called VisuaLinda, which is a Linda server itself as well as a visualization tool. Since the visualization module is built-in the Linda server, programmers do not need to insert/delete additional sentences into/from their client programs in order to obtain visualization. This framework extremely reduces the programmers' work in debugging parallel programs and helps prevent the probe e ect, which is a main concern in monitoring parallel programs. Secondly, the VisuaLinda uses threedimensional space to display both the relation between Linda server and clients, and their execution. This framework allows us to display much larger number of processes than in 2D, to see two relations simultaneously, to improve the visibility of communication lines, and to see each process's state as well as an overview of the execution.
