Data provenance, or data lineage, describes the life cycle of data. In scientific workflows on HPC systems, scientists often seek diverse provenance (e. g. , origins of data products, usage patterns of datasets). Unfortunately, existing provenance solutions cannot address the challenges due to their incompatible provenance models and/or system implementations. In this paper, we analyze four representative scientific workflows in collaboration with the domain scientists to identify concrete provenance needs. Based on the first-hand analysis, we propose a provenance framework called PROV-IO ^+, which includes an I/O-centric provenance model for describing scientific data and the associated I/O operations and environments precisely. Moreover, we build a prototype of PROV-IO ^+ to enable end-to-end provenance support on real HPC systems with little manual effort. The PROV-IO ^+ framework can support both containerized and non-containerized workflows on different HPC platforms with flexibility in selecting various classes of provenance. Our experiments with realistic workflows show that PROV-IO ^+ can address the provenance needs of the domain scientists effectively with reasonable performance (e. g. , less than 3. 5% tracking overhead for most experiments). Moreover, PROV-IO ^+ outperforms a state-of-the-art system (i. e. , ProvLake) in our experiments.
