Welcome to the jungle, a set of machines with no imposed rules that are fully
controlled and maintained by their users.

The configuration of all the machines is written in a centralized [git
repository][jungle] using the Nix language for NixOS. Changes in the
configuration of the machines are introduced by merge requests and pass a review
step before being deployed.

All jungle machines have access to the large list of packages (>120k) available
in [Nixpkgs][nixpkgs] and a custom set of [BSC packages][overlay] specifically
tailored to our needs for HPC machines. Users can install any packages on their
own or request them to be system-wide available for all users.

We have put a lot of effort to guarantee very good reproducibility properties in
the configuration of the machines and the software they use.

To enter the jungle machines follow the [instructions](access) to submit a
request.
