IVPrototype is an information visualization prototype for the visualization of both geometrical and non-geometrical data. Our goal is to provide a generic system that automatically generates data visualization and dynamically adapts the interface according to the data in order to control the amount of information displayed. The information is organized in one or several information groups, which aggregate semantically related information. Icons and coloured surfaces are the visual mappings provided. Other features of this prototype are: a data independent architecture; several filtering mechanisms; use of degree of interest functions; automatic selection of icons based on scale factor and semantic criteria.

MPVisualizer (Message Passing Visualizer) is a tool for the monitoring and debugging of message passing parallel applications with three components: the trace/replay mechanism, the graphical user interface and a central component, called visualization engine. The engine, which plays the main role during the replay phase, builds an object-oriented model of the application. Taking full advantage of inheritance and polymorphism the tool can be adapted to different message passing environments and different graphical environments, and easily reprogrammed to detect specific predicates. The engine is also prepared to recognize race conditions.
