DeHiFo-an advanced HPF debugging system

Debuggers are critical tools for the 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 presents 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 the user. To be practical, the debugger has to support interactive source-level debugging of large-scale applications on large machines. In this paper we deene design goals for the HPF debuggers and present an architecture of an advanced HPF debugging system DeHiFo, which addresses several challenges involved and provides signiicant contributions into the existing debugging technology. The 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 diierent universities.
