Hello! Some news to break the silence on this list… On the Guix-HPC blog, we announced last week what HPC practitioners and scientists interested in reproducible research may like from the new 1.2.0 release: https://hpc.guix.info/blog/2020/11/hpc-reproducible-research-in-guix-1.2.0/ A bit earlier, Konrad Hinsen wrote an article entitled “The four possibilities of reproducible scientific computations” that in my opinion very nicely summarizes requirements for a “reproducible computation” and their implications: https://blog.khinsen.net/posts/2020/11/20/the-four-possibilities-of-reproducible-scientific-computations/ It effectively rules out pre-built binaries (Docker images) as well as SaaSS (Binder), but it does so in a way that demonstrates how they fail some of the basic high-level criteria rather than entering a technical debate.
