No, it's not. First of all, reproducible installations for HPC nodes is a solved problem (we have xCAT to boot, for example). However the biggest factor is the hardware we use on these nodes.

An HPC node contains an Infiniband interface, at least, and you generally use manufacturer provided OFED for optimal performance, which requires a supported kernel.

I wasn't talking about NixOS or GuixSD, or OS installation.

I was talking about tools that let you run ancient software on modern distros. With Nix and Guix you don't have to hold your whole OS back just to run 'ancient software'.

We use user mode containers for that. Mostly Apptainer. It supports MPI, GPU and other bells and whistles that we need.
