State Based Visualization of PVM Applications(9)

Abstract. Understanding the dynamic behavior of parallel programs is a critical issue both for debugging and for optimization. A visualization tool displaying an animated sequence of the global states the program runs through offers valuable support for th

state snapshot selected in the visualizer.This will be achieved by automatically restarting the application from the last available checkpoint prior to the selected snapshot and by using the deterministic execution controller to ensure that the selected state is reached even in the presence of nondeterminism due to message races.In this way debugging large programs with high execution times will be efficiently supported.
