A hypermedia distributed application for monitoring and fault-injection in embedded fault-tolerant parallel programs

We describe a distributed, multimedia application which is being developed in the framework of the ESPRIT-IV Project 21012 EFTOS (Embedded Fault-Tolerant Supercomputing). The application dynamically sets up a hierarchy of HTML pages reflecting the current status of an EFTOS compliant dependable application running on a Parsytec CC system. These pages are fed to a World Wide Web browser playing the role of a hypermedia monitor. The adopted approach allows the user to concentrate on the high level aspects of his/her application so to quickly assess the quality of its current fault tolerance design. This view of the system lends itself well for being coupled with a tool to interactively inject software faults in the user application; this tool is currently under development.
