摘要

Debugging can help programmers' to locate the reason for incorrect program behavior. Parallel programs' executions are much more complex than those of serial ones, which make it difficult to debug parallel programs. In contrast with traditional parallel and distributed computing environments, some new characteristics, such as largely heterogeneous and dynamic, security, and etc, appear in computational grids. These new features challenge debugging grid applications. In this paper, we design and implement a grid-enabled parallel debugging environment to simply debug grid applications. We present the concept of ad hoc computing environment in grids and the method by which this environment can be built automatically constrained to MPI-G2 application. Some capabilities, including user identification, automatic task submission, resource registering and collection can be accomplished easily through the portal. The debugging functionalities include consistent global state and race detection.
