SUMMARY:Assessing Reproducibility: An Astrophysical Example of Computation
 al Uncertainty in the HPC Context
DESCRIPTION:Victoria Stodden and Matthew S. Krafczyk (University of Illino
 is)\n\nWe present an experiment using the Enzo simulation code on NCSA's B
 lue Waters system to highlight the importance of computational and numeric
 al uncertainty in scientific computing on HPC systems. We quantify the (su
 rprising) variability of outputs from 200 identical simulation runs. We ma
 ke two recommendations to improve the assessment of reproducibility of com
 putational results: the inclusion of computational variability measures in
  standard reporting practices; and modular software designs that permit lo
 calized assessments of the source of computational uncertainty.\n\nTag: Re
