DeHiFo-an advanced HPF debugging system

Debuggers are critical tools for software development. The design and implementation of a source-level debugging system that enables the HPF programmer to observe the behavior of the program at the level at which the program has been developed present unique challenges. The main requirement put on an HPF debugger is to observe and control the state of many processors, to summarize and present distributed information in a concise and clear way, in terms of the source program. To be practical, the debugger has to support interactive source-level debugging of large-scale applications on large machines. In this paper we define design goals for HPF debuggers and present an architecture of an advanced HPF debugging system DeHiFo, which addresses several challenges involved and provides significant contributions to existing debugging technology. An HPF debugger is a rather complex system. Its development requires a systematic cooperation between several partners. DeHiFo is an excellent example of cooperation and technology transfer among research teams working at different universities
