Interoperability of Run-Time Tools
for Parallel and Distributed Programs

As a case study, we are looking at an environment, where a debugger, a program flow visualizer, a checkpointing system and a deterministic execution controller interoperate in order to support the efficient and comfortable debugging of programs with high execution times. Using this case study, the problems that arise when combining different run-tools are analyzed and classified. To solve these problems, a method for tool interaction and a supporting software infrastructure are developed. A model of the target system and the tools' accesses enables the systematic analysis and the elimination of conflicts during the data integration. The concept of mediators is used to support behavioral integration without creating mutual dependencies between the tools. The mediators are implemented by the already available monitoring system, which allows to dynamically link the necessary external interfaces into the tools.
