Integrated debugging and performance monitoring for parallel programs

Based on experiences with various debugging tools, the authors believe that the ideal tool represents several forms of integration: integration of scope from simple debugging to advanced performance monitoring; integration of techniques such as graphical and textual displays and real-time and postmortem analysis; connections between event monitoring and execution control; coordination of instrumentation in the parallel operating system with that in the tool; and a considered user interface throughout all components of the tool. Each of these forms of integration is briefly discussed
