Workflow provenance data have historically enabled critical capabilities towards RTAI. Provenance data derivation paths contribute to responsible workflows through transparency in tracking artifacts and resource consumption. Provenance data are well-known for their trustworthiness, helping explainability, reproducibility, and accountability. However, there are complex challenges to achieving RTAI, which are further complicated by the heterogeneous infrastructure in the computing continuum (Edge-Cloud-HPC) used to develop and deploy models. As a result, a significant research and development gap remains between workflow provenance data management and RTAI. In this paper, we present a vision of the pivotal role of workflow provenance in supporting RTAI and discuss related challenges. We present a schematic view of the relationship between RTAI and provenance, and highlight open research directions.} } @inproceedings{coletti_2024, author = {Mark Coletti and Renan Souza and Tyler J.

Integrated data analysis plays a crucial role in scientific discovery, especially in the current AI era, by enabling Responsible AI development, FAIR, Reproducibility, and User Steering. However, the heterogeneous nature of science poses challenges such as dealing with multiple supporting tools, cross-facility environments, and efficient HPC execution. Building on data observability, adapter system design, and provenance, we propose MIDA: an approach for lightweight runtime Multi-workflow Integrated Data Analysis. MIDA defines data observability strategies and adaptability methods for various parallel systems and machine learning tools. With observability, it intercepts the dataflows in the background without requiring instrumentation while integrating domain, provenance, and telemetry data at runtime into a unified database ready for user steering queries. We conduct experiments showing end-to-end multi-workflow analysis integrating data from Dask and MLFlow in a real distributed deep learning use case for materials science that runs on multiple environments with up to 276 GPUs in parallel. We show near-zero overhead running up to 100,000 tasks on 1,680 CPU cores on the Summit supercomputer.} } @inproceedings{rosendo2023provlight, title={{ProvLight}: Efficient Workflow Provenance Capture on the Edge-to-Cloud Continuum}, author={Rosendo, Daniel and Mattoso, Marta and Costan, Alexandru and Souza, Renan and Pina, D{\'e}bora and Valduriez, Patrick and Antoniu, Gabriel}, booktitle={IEEE International Conference on Cluster Computing}, doi={10.1109/CLUSTER52292.2023.00026}, url={https://www.computer.org/csdl/proceedings-article/cluster/2023/079200a221/1SfUrCnjgAM}, pdf={https://arxiv.org/pdf/2307.10658}, year={2023} } @inproceedings{cunha_2021_context, title={Context-aware Execution Migration Tool for Data Science Jupyter Notebooks on Hybrid Clouds}, author={Cunha, Renato LF and Real, Lucas V and Souza, Renan and Silva, Bruno and Netto, Marco AS}, booktitle={IEEE International Conference on e-Science}, year={2021}, doi={10.1109/eScience51609.2021.00013}, pdf={https://arxiv.org/pdf/2107.00187.pdf} } @inproceedings{azevedo_supporting_2021, title={Supporting Polystore Queries using Provenance in a Hyperknowledge Graph}, author={Azevedo, Leonardo and Souza, Renan and Soares, Elton and Thiago, Raphael and Oliveira, Anna and Moreno, Marcio}, booktitle={International Semantic Web Conference (ISWC)}, year={2021}, pages = {1--4}, pdf = {http://ceur-ws.org/Vol-2980/paper368.pdf} } @inproceedings{souza_2021_ctd_sbbd, title={User Steering Support in Large-scale Workflows}, author={Souza, Renan}, booktitle = {PhD Thesis Contest: Brazilian Symposium on Databases ({SBBD})}, year={2021}, pdf = {https://sol.sbc.org.br/index.php/sbbd_estendido/article/download/18185/18019} } @inproceedings{soares_2021_recommender, title={A Recommender for Choosing Data Systems based on Application Profiling and Benchmarking}, author={Soares, Elton and Souza, Renan and Thiago, Raphael and Machado, Marcelo and Azevedo, Leonardo}, booktitle={Brazilian Symposium on Databases ({SBBD})}, year={2021}, pages = {265-270}, pdf = https://sol.sbc.org.br/index.php/sbbd/article/download/17883/17717/} } @inproceedings{brandao2020cycle, title={Cycle Orchestrator: A Knowledge-Based Approach for Structuring Cyclic ML Pipelines in the O\&G Industry}, author={Brand{\~a}o, Rafael and Louren{\c{c}}o, Vitor and Machado, Marcelo and Azevedo, Leonardo and Cardoso, Marcelo and Souza, Renan and Lima, Guilherme and Cerqueira, Renato and Moreno, Marcio}, booktitle={International Semantic Web Conference (ISWC)}, year={2020} } @inproceedings{brandao2020knowledge, title={A Knowledge-Based Approach for Structuring Cyclic Workflows}, author={Brand{\~a}o, Rafael and Louren{\c{c}}o, Vitor and Machado, Marcelo and Azevedo, Leonardo and Cardoso, Marcelo and Souza, Renan and Lima, Guilherme and Cerqueira, Renato and Moreno, Marcio}, booktitle={International Semantic Web Conference (ISWC)}, year={2020} } @inproceedings{souza_runtime_2020, title = {Runtime Steering of Parallel CFD Simulations}, booktitle = {International Conference on Parallel Computational Fluid Dynamics}, author = {Souza, Renan and Camata, J. and Mattoso, Marta and Coutinho, Alvaro}, year = {2020} } @inproceedings{azevedo_experiencing_2020, title = {Experiencing {ProvLake} to Manage the Data Lineage of AI Workflows}, booktitle = {Innovation Summit on Information Systems (EISI) in Brazilian Symposium in Information Systems (SBSI)}, author = {Azevedo, Leonardo and Souza, Renan and Thiago, Raphael and Soares, Elton and Moreno, Marcio}, year = {2020} } @inproceedings{azevedo_federated_2020, title = {Modern Federated Databases: an Overview}, booktitle = {International Conference on Enterprise Information Systems (ICEIS)}, author = {Azevedo, Leonardo and Souza, Renan and Soares, Elton and Moreno, Marcio}, year = {2020} } @inproceedings{souza_aapg_2020, title = {Supporting the Training of Physics Informed Neural Networks for Seismic Inversion Using Provenance}, booktitle = {American Association of Petroleum Geologists Annual Convention and Exhibition ({AAPG})}, author = {Souza, Renan and Codas, A. and Nogueira Junior, J.

Despite being part of the same project, each team manages its own workflows, using specific execution environments and data processingtools. Analyzing the data processed by all workflows globally is a core task in a CSE project. However, this analysis is hard because the data generated by these workflows are not integrated. In addition, since these workflows may take a long time to execute, data analysis needs to be done at runtime to reduce cost and time of the CSE project. A typical solution in scientific data analysis is to capture and relate the data in a provenance database while the workflows run, thus allowing for data analysisat runtime. However, the main problem is that such data capture competes with the running workflows, adding significant overhead to their execution. To mitigate this problem, we introduce in this paper a system called ProvLake, which adopts design principles for providing efficientdistributed data capture from the workflows. While capturing the data, ProvLake logically integrates and ingests them into a provenance database ready for analyses at runtime. We validated ProvLake ina real use case in the O&G industry encompassing four workflows that process 5TB datasets for a deep learning classifier. Compared with Komadu, the closest solution that meets our goals, our approach enables runtime multiworkflow data analysis with much smaller overhead, such as 0.1\%.} } @inproceedings{souza_managing_2019, title = {Managing Data Traceability in the Data Lifecycle for Deep Learning Applied to Seismic Data}, url = {https://www.searchanddiscovery.com/abstracts/html/2019/ace2019/abstracts/1718.html}, booktitle = {American Association of Petroleum Geologists Annual Convention and Exhibition ({AAPG})}, author = {Souza, Renan and Brazil, Emilio Vital and Azevedo, Leonardo and Ferreira, Rodrigo and Chevitarese, Daniel and Soares, Elton and Thiago, Raphael and Nery, Marcelo and Torres, Viviane and Cerqueira, Renato}, year = {2019} } @inproceedings{souza_provenancedata_2019, title={Provenance Data in the Machine Learning Lifecycle in Computational Science and Engineering}, author={Souza, Renan and Azevedo, Leonardo and Lourenço, Vítor and Soares, Elton and Thiago, Raphael and Brandão, Rafael and Civitarese, Daniel and Vital Brazil, Emilio and Moreno, Marcio and Valduriez, Patrick and Mattoso, Marta and Cerqueira, Renato and A.

In Computational Science and Engineering (CSE), the complexity of the ML lifecycle comes from the large variety of data, scientists' expertise, tools, and workflows. If data are not tracked properly during the lifecycle, it becomes unfeasible to recreate a ML model from scratch or to explain to stakeholders how it was created. The main limitation of provenance tracking solutions is that they cannot cope with provenance capture and integration of domain and ML data processed in the multiple workflows in the lifecycle while keeping the provenance capture overhead low. To handle this problem, in this paper we contribute with a detailed characterization of provenance data in the ML lifecycle in CSE; a new provenance data representation, called PROV-ML, built on top of W3C PROV and ML Schema; and extensions to a system that tracks provenance from multiple workflows to address the characteristics of ML and CSE, and to allow for provenance queries with a standard vocabulary. We show a practical use in a real case in the Oil and Gas industry, along with its evaluation using 48 GPUs in parallel.} } @inproceedings{souza_towards_2018, location = {Rio de Janeiro, Brazil}, title = {Towards a human-in-the-loop library for tracking hyperparameter tuning in deep learning development}, pdf = {http://ceur-ws.org/Vol-2170/paper12.pdf}, eventtitle = {Latin American Data Science ({LaDaS}) workshop co-located with the Very Large Database ({VLDB}) conference}, pages = {84--87}, booktitle = {Latin American Data Science ({LaDaS}) workshop co-located with the Very Large Database ({VLDB}) conference}, author = {Souza, Renan and Neves, Liliane and Azeredo, Leonardo and Luiz, Ricardo and Tady, Elaine and Cavalin, Paulo and Mattoso, Marta}, year = {2018} } @inproceedings{Silva2018Capturing, title = {Capturing Provenance for Runtime Data Analysis in Computational Science and Engineering Applications}, isbn = {978-3-319-98379-0}, series = {Lecture Notes in Computer Science ({LNCS})}, pages = {183--187}, booktitle = {Provenance and Annotation of Data and Processes - International Provenance and Annotation Workshop (IPAW)}, publisher = {Springer International Publishing}, author = {Silva, Vítor and Souza, Renan and Camata, Jose and de Oliveira, Daniel and Valduriez, Patrick and Coutinho, Alvaro L.
