  Whole Tale http://wholetale.org is a web-based, open-source platform for
reproducible research supporting the creation, sharing, execution, and
verification of "Tales" for the scientific research community. Tales are
executable research objects that capture the code, data, and environment along
with narrative and workflow information needed to re-create computational
results from scientific studies. Creating reproducible research objects that
enable reproducibility, transparency, and re-execution for computational
experiments requiring significant compute resources or utilizing massive data
is an especially challenging open problem. We describe opportunities,
challenges, and solutions to facilitating reproducibility for data- and
compute-intensive research, that we call "Tales at Scale," using the Whole Tale
computing platform. We highlight challenges and solutions in frontend
responsiveness needs, gaps in current middleware design and implementation,
network restrictions, containerization, and data access. Finally, we discuss
challenges in packaging computational experiment implementations for portable
data-intensive Tales and outline future work.
