After my short piece, “A hard road to reproducibility,” appeared in Science, I received several emails and Twitter mentions asking for more specific tips—both about tools and documents we use in the group to train the team about reproducibility. In answer to popular demand, then, I have collected here what we could call the “Barba-group... Continue »

The hard road to reproducibility

Science 07 Oct 2016 cover

by Lorena A. Barba Science 07 Oct 2016: Vol. 354, Issue 6308, pp. 142 DOI: 10.1126/science.354.6308.142 Early in my Ph.D. studies, my supervisor assigned me the task of running computer code written by a previous student who was graduated and gone. It was hell. I had to sort through many different versions of the code,... Continue »

Numba: Tell those C++ bullies to get lost

Reproducible and replicable CFD: it's harder than you think

Choosing an incorrect boundary condition with IBAMR resulted in spurious blockage of vortices at the outlet. Thanks to the support received in the code users' forum, this and other problems were resolved and we succeeded in replicating previous findings.

Reproducible and replicable CFD: it's harder than you think. Submitted: 13 May 2016. Preprint arXiv:1605.04339 Accepted: 13 Oct. 2016, Computing in Science and Engineering. Overview We do our best to accomplish reproducible research and have for years worked to improve our practices to achieve this goal. Barba made a pledge in 2012, the “Reproducibility PI Manifesto,” according... Continue »
