gLite Job Provenance—a job‐centric view

Job Provenance (JP), part of the gLite Grid middleware, is a service that keeps long‐term trace on completed computations for further reference. It is a job‐centric service, keeping records about job life cycle, its environment, inputs/outputs, user parameters, and annotations. During the first provenance challenge, we explored the relation between a specific job‐centric Grid‐oriented provenance and a more general data provenance approach. The challenge represents a use case which emphasizes fields that were not priorities in the original JP design. However, we proved that the design is sufficiently general to cope with this mode of use. We also identified several areas where it is feasible to extend the current implementation.
