Ad Hoc Debugging Environment for Grid Applications

Debugging can help programmers to locate the reasons for incorrect program behaviors. The dynamic and heterogeneous characteristics of computational grids make it much harder to debug grid applications. In this paper, we give the definition the concept of ad hoc debugging environment, which uncover the nature of debugging behavior in computational grids. Besides solving some normal problems in tradition parallel debugging, such as user interface, application instrumentation, we first address the nondeterministic dynamic behavior of computing environment in grids during the debugging session. We evaluate the similarity between computing environments, in which the grid application can be re-executed for cyclic debugging.
