Abstract
Graphical representations of a program execution (also called visualization) have been shown to be useful to understand the behavior of parallel programs. Visualization of an execution is generally done off-line, using an adequate trace generated during execution. However, during the debugging phase, such representations may turn out to be insufficient: use of a symbolic debugger may also be required. The goal of this paper is to show that execution replay is the basic component that must be used to integrate a symbolic debugger with a visualization tool. Such an integration allows a simultaneous use of both tools during an execution, leading to an ideal observation of the execution: low level observation thanks to the debugger, and high level observation thanks to the visualization. This new approach has been implemented for parallel programs running on an iPSC/2.
