Monkeying around with nix for HPC systems which have no root access and NFS filesystems. Background Nix is not well known for being friendly to users without root access. This is typically made worse by the “exotic” filesystem attributes common to HPC networks (this also plagues hermes). An earlier post details how and why proot failed. The short pitch is simply: Figure 1: Does your HPC look like this?| rgoswami.me
Background My move away from the powerful, but unimaginatively named HPC clusters of IITK 1 brought me in close contact with the Lua based 2 lmod module system. Rather than fall into the rabbit hole of brew we will leverage the existing system to add our new libraries. Not finding any good collections of these composable environments, and having failed once before to install Nix as a user without admin access, I decided to start my own collection of Lmod recipies.| rgoswami.me
