SUMMARY:Trustworthy Computational Evidence Through Transparency and Reprod
 ucibility
DESCRIPTION:Invited Talk\n\nTrustworthy Computational Evidence Through Tra
 nsparency and Reproducibility\n\nBarba\n\nMany high-performance computing 
 applications are of high consequence to society. Global climate modeling i
 s an historic example of this. In 2020, the societal issue of greatest con
 cern, the still-raging COVID-19 pandemic, saw a legion of computational sc
 ientists turn their endeavors to new research projects in this direction. 
 Applications of such high consequence highlight the requirement of buildin
 g trustworthy computational models. Emphasizing transparency and reproduci
 bility have helped us build more trust in computational findings. In the c
 ontext of supercomputing, however, we may ask: how do we trust results fro
 m computations that cannot be repeated? Access to supercomputers is limite
 d, allocations are finite and machines are decommissioned after a few year
 s. I had the distinction to serve as SC19 Reproducibility Chair, and contr
 ibute to the strengthening of this initiative for SC. I was also a member 
 of the National Academies study Committee on Replicability and Reproducibi
 lity in Science, which released its report last year. There, reproducibili
 ty is defined as "obtaining consistent computational results using the sam
 e input data, computational steps, methods, code and conditions of analysi
 s." We should ask how this can be ensured, certified even, without exercis
 ing the original digital artifacts. This is often the situation in HPC. It
  is compounded now with greater adoption of machine learning techniques, w
 hich can be opaque. The ACM in 2017 issued the Statement on Algorithmic Tr
 ansparency and Accountability, targeting algorithmic decision-making using
  data models. Among its seven principles, it calls for data provenance, au
 ditability, validation and testing. These principles can be applied not on
 ly to data models, but to HPC in general. In this talk, I want to discuss 
 the next steps for reproducibility: how we may adapt our practice to achie
 ve what I call <em>unimpeachable provenance</em>, and achieve full auditab
 ility and accountability of scientific evidence produced via computation.\
