it was also my first thought on abstractions of abstractions, thanks for sharing :) could you elaborate a bit more on why HPC world is special when it comes to configuring the environment? I always feel it is a typical problem in software development, to separate operating system env from the application env. do you use spack / easybuild on your personal computer, for example if you need to install a package that is not part of the distribution? |

There isn’t anything particularly special about the HPC world other than the need for many different configurations of the same software for many different CPU and GPU architectures. You might want to have several versions of the same application installed at once, with different options or optimizations enabled. Spack enables that. Environments are one way to keep the different software stacks separate (though, like nix, spack uses a store model to keep installs in separate directories, as well).
