GeoTrust: Improving Sharing and Reproducibility of Geoscience Applications

Dr. Tanu Malik

School of Computing - DePaul University 


A critical barrier to achieving the vision of cross-disciplinary science is that of scientific reproducibility - the ability to independently verify the work of other scientists.  A major obstacle to achieving scientific reproducibility is the lack of appropriate incentives for sharing code and data.  But, even when incentives for sharing code and data exist, it is extremely challenging to verify and validate modern science which is decidedly computational and data- intensive.

In this talk I will present the NSF EarthCube - funded GeoTrust project that will establish trust in scientific results by making them easy to share, reproduce and verify.  GeoTrust builds upon the novel concept of a 'scinuit', a self-contained package that includes all data elements associated with an instance (run) of a computational experiment, including input files, parameter files, the mode executable and any associated libraries, and all output files (results) produced.  It is developing and establishing a reproducible research framework consisting of client tools and hosted servers, which will automatically create and host sciunits of computational experiments and their associated scientific results.  Verifiable results will be associated with 'stamps of reproducibility', establishing community recognition of verified computational experiments.  The talk will describe the reproducible research framework in the context of geoscience use cases and community infrastructures.
