A Practical Provenance Query Framework for Parallel and Distributed  
Scientific Scripting Applications

Abstract:
Provenance management systems for parallel and distributed scientific  
scripting applications enable the analysis of complex computational  
experiments in different conceptual dimensions. They allow for one to  
extract the precise lineage of data artifacts generated by the  
experiments in order to explain the processes used to generate them.  
In this work we present a data model geared towards scientific  
scripting applications, that enriches structural provenance data with  
information about the runtime behavior in high performance computing  
environments, and scientific application specific parameters. This  
provenance data model is implemented in a relational database. We  
survey provenance query patterns and present queries that match these  
patterns to correlate structural provenance, runtime data, and  
scientific parameters to provide useful information to the scientist.  
Finally, we abstract common provenance patterns into functions and  
stored procedures in the relational database in order to improve the  
provenance system's usability.

Bio:
Luiz Gadelha is currently a D.Sc. student at the Computer and Systems  
Engineering Program of the Federal University of Rio de Janeiro. His  
research is concerned with security, scalability, and expressiveness  
of provenance systems in e-Science. He is also a technologist at the  
National Laboratory for Scientific Computing, in Brazil.

Information: Lunch will be provided
